OpenBeam isn’t useful for much other than to whack people with unless if you have the screws to use it with.

These are common M3 x 6mm Button Head Socket Cap Screw (M3x6 BHCS), which is part of the charm of OpenBeam. Standard hardware to make cool things!

Some people call’em screws, some bolts. Whatever it is, they make connecting things together easier!

Works great with their mating nuts.

Sold in bulk packs of 100.
