There's a reason lag bolts aren't sold in bulk and are expensive. It's because the average consumer doesn't need them in bulk so it would not be profitable to try and sell them that way. If you're building a porch and are attaching the frame to the house you only need 8 or so lag bolts, not a box of 100. Because they don't sell them in bulk they mark up the prices to make up the difference so they can still turn a profit. Ebay is probably your best bet in this case, good luck

Or even a bolt and screw merchant.

In socal we have enough industry that there are specialized 'screw and bolt' hardware vendors that that is all they sell, and will sell to consumers for no real deal, you just need to walk in and place an order.

My local Ace hardware has them in singles and in boxes. I don't know if you have them in the south.

To buy a lot of them you really should go to a specialist merchant. There will be companies that specialise in screw fixings.

I get lag bolts at Fleet Farm. They sell them in bulk priced by the pound (maybe ~$1.40/lb last I saw, though I think that was a sale). So some hardware stores do sell them in bulk, but Fleet Farm is only in the northern midwest. If you don't find a local place or somewhere cheap online, you might call a Fleet Farm and see if they'll ship you some.

Farm and Fleet, Tractor Supply, Rural King and Ace Hardware all sell lag bolts in bulk and those are just 4 stores in my immediate area. Go to smaller stores, big box stores usually don't sell anything in bulk.

And yes, they're expensive everywhere. The manufacturing method is more expensive than it is for bolts and the expense is passed on to the consumer.

TSC, Grainger or Fastenal

10" lag bolts will ass-rape you on cost. If you can then switch to bolts and nuts using something like a carriage bolt. I think it will save you money.

>grainger, cheap
Convenient not cheap

Fastenal? We do get bulk boxes of 1/4" lags, I'll check from who.

Thanks everyone im reading your replies.

But busy to give a proper response.

I had a website that I could download them, but it was always buffering.

You would absolutely be better served to get a wood auger and just carriage bolt with loctite. What will end up happening sooner or later with lag bolts is they will rust inside the wood and eventually pop out from pressure. Carriage bolts will rust and become more like a solid piece of metal outside the wood. How pumped are your grandkids gonna be when they can say grandpa built a fucking indestructible bridge

>>1019811

>Carriage with lock tite

It will rust the same as a lag bolt

>pop out with pressure

No, they "pop out" because they have rusted and the threads are totally dead. Technically they fall out. Which carriage bolts also do.

If he were to go carriage he should use them as intended and get them long enough to go straight through with enough out on the other side to get a nut and washer on.

But with that he can go with a regular hex bolt because carriage bolts are to be used where you don't want things/people snagging on the heads of a lag bolt, hex bolt or other fastener

10" are going to rape you no matter what.

>>1019851

My point is carriage bolt will hold together forever and there will be no trip hazard on the bridge surface. The carriage bolt cannot fall out because of the head shape, but the nut could shear threads and fail with massive over strain. With lag bolts you have a trip hazard, since it relies on threads for all it's hold when the threads rust it fails instead of just becoming solid. Also threads inside a nut sealed with loctite will almost never let go without incredible pressure. If I'm being honest though I tend to over build everything I do

>carriage bolts will hold together forever

So what kind of super metal are your carriage bolts are made of while the ones I have used to put together a bench 2 years ago have turned into dust and have been sheering at the head.

>>1019574
I used over 150 of them on a modest gazebo and shed for hinge plates or rafter connections,and nearly got sucked into Homo Depot and bs

>>1019924
Were they galvanized?

>>1019924
Stainless would last past the point where the wood turns to dust. But if OP doesn't like the price of regular fasteners, I doubt he'll be interested in stainless ones.

>>1019811
Hot dipped lags will not rust in your lifetime even in treated wood.

>>1019574
This, there is a bolt and supply store near me that sells nothing but bolts, fasteners, and safety equipment.

If you want cheap maybe you can find threaded rod cheaper. Keep in mind you will need a washer and nut for each side(2 nuts, 2 washers, one piece of rod). Downside is you'll need to cut every piece.

For durability galvanized carriage bolts will go a long way. If you have the budget for it titebond iii on joints for pieces you'll never have to remove before you tighten down the bolt will last a good amount of time. So I wouldn't glue the walking surfaces down, those will need to be replaced before the rest of the bridge, hopefully.

The way I'd do it, site unseen.

Sonotube
Cement meant for use around water(not my trade, I'd ask my buddies who it professionally for advice)
Pressure treated wood rated for ground contact
All galvanized hardware
Epoxy based wood sealer

Basically same way i'd build a deck.

If the distance between the 2 tops of the embankment is rather large i'd wait for a dry season when the creeks at its lowest point, rent an auger machine, temporarily dam the creek, and then place 2 pieces of sonitube several feet deep and setting proud several feet as well and fill them with concrete. I'd implant a 4x4 bracket into the concrete. I'd ask the concrete guys if I should reinforce it as well. Concrete will set underwater, I'd only be concerned with damming the creek to make sure the tube lasts longer enough for the concrete to at least set

I'd rather not do that though, only if absolutely necessary.

>>1020184
Otherwise I'd just set up sonotube near the 4 corners of the bridge and do the same thing with with with the 4x4 bracket. Probably somewhere down the embankment. I'd make trusses at both sides that meet towards the middle of the bridge to take some of the load. I would use 2 carriage bolts at every joint I could to resist movement. Then just create a level surface to place boards across for walking. If the bridge is more than 4 feet wide I'd do a support down the center as well. As for railing I would space it evenly between any point where cross bracing starts to spread the load out more evenly. I could maybe spend 9001 hours in MS paint if you're interested in what I'm talking about, I know I'm doing a shit job explaining it.

But afterwards I'd treat the whole thing with one of those UV and water resistant epoxy sealers that are commonly used for decking, the strongest one I can find, and preferably one that doesn't require the old finish to be removed before reapplying so in 10-15 years you can just wash the bridge down and throw a new coat on. Probably won't even need to, but it's preventive maintainece.

But that's just how I'd do it, I'm sure you have your own plan already. I was just having fun thinking about what I'd do in that situation.

at prices 20% higher than everywhere else because they're convenient, they're for contractors who pass the cost on directly, and they don't want to see one box to Joe Blow, they want to sell a skid to a contractor.

Bolt Depot! We use them at work all the time.
www.boltdepot.com

>>1020084
They are open to the public.

>>1019982

They were. I am.not sure what grade but they were but the treated yellow pine that was getting eaten by termites outlasted them

>>1019924
Zinc plated pot metal isn't galvanized steel retard, galvanized lag screws don't magically last longer than galvanized carriage bolts.

>>1020399

Exactly and my point was that galvanized carriage bolt will not last longer than a glavanized lag bolt.

Do you guys really not use stainless bolts for outdoor shit? I use 316 for anything that could ever get wet

>what grade
Do you mean "what grade" of zinc plating? Because there are different kinds of zinc plating, and that's a different process from hot-dip galvanization, which is what "galvanized" refers to. Zinc plating is cheaper than but inferior to galvanization for corrosion resistance. Galvanized fasteners have a dull silvery-grey look, while zinc plated fasteners are shiny silver, blue, or yellow.

>>1019563
Home Depot is always cheaper for building materials than Lowe's. Not by much though. Usually can get a contractor's pack.

>>1019924
I have SEEN carriage bolts that were installed on a grader in 1956 only need a thread chase and heat to be removed. This is because they were put together with an adhesive like loctite, which sealed out the air. I'm not saying steel lasts infinitely, I'm saying you can build something out of metal so that it holds for a long time. I mean, you could pilot a hole for lag bolts, fill it with acoustic sealant, and maybe they would last 100 years if the wood doesn't move too much. You probably should have painted the clean bolts on your shitty bench

>>1020026
That's not true.
http://www.deckmagazine.com/decking/fighting-fastener-corrosion.aspx
The simple fact is steel will corrode in treated wood, more so in this day and age due to new treatment methods. It is more effective and economical to rely on a sealed nut and thread, than on course threads and friction in treated wood.

>>1020461

They were hot dipped then.

>>1020427
This. The cost of the stainless hardware is trivial compared to the wood cost. Why not just spend the extra little bit?

>>1019563
SPAX

that is all

>>1020461
The yellow is cadmium you dumb fuck

>>1020875
NHB but they have "yellow" zinc finish. I do not know what the yellow color comes from, but it is not cadmium.

I don't think you can even buy cadmium plated steel in big box stores these days, they're trying to phase it out as much as possible.

>>1020875
>>1020876
Yellow-plated fasteners these days are typically chromate over zinc.

>>1020549
Dude I would go so far as to say hot dipped lags can reasonably be expected to last five decades+ in marine applications

They just don rust

>>1021146

As someone who lives on the seafront and works on the sea I would go so far to say that you are full of shit that hot dipped anything will start to rust within the year in the most sedate marine environment and show spots in a month in a harsher environment.

Now if you were to paint them and paint them every six months then you are alright but for the cost of paint you were better off just using stainless anyway or let it rust if you don't care.

We care because we are in tourism and tourists hate seeing rust.
