I'm trying to find some M7 Allen head bolts, but I'm having a hard time finding exactly what I need because I'm not too familiar with the terminology of fasteners. I'm looking for an Allen head bolt where the head tapers in towards the threads, but all I'm finding are bolts like pic related where the head tapers away from the threads. I want something with the same amount of taper and the same sized head, like if you took these bolts and flipped the heads upside down.
Would anyone know the name of a bolt like that or where I could find them?
go to a fastenal store with the bolt you broke.
They probably won't be able to match the exact bolt head shape but they can get you close. If you're using it in a low clearance space you may need to drill it out a bit.

You want an M7 CSSC (countersunk cap screw)

Thanks. The head of the bolt and the taper is a bit more thin than I'd like, but I don't know if it's going to get much better than that. Might go by a hardware store to pick some up and see how they work.
This is a picture of the original bolt that I'm trying to get a similar fit to. It's used to hold a center cap onto a wheel. The bolt is a special one made by the wheel manufacturer, but you need a special tool for it. That's why I'm trying to find an Allen head.

M7 is terribly hard to find over at my area. Your area might differ. The brake calipers on old mercedes are bolted together with M7 bolts. Fuck it was hard to find them when I fixed the calipers!
