Finally got these to replace some worn bolts on my milling machine jig, and the hex socket drive engages perfectly without any stripping. They're solid alloy steel and the pack of 200 is more than enough for multiple setups.

Driving these into hardened steel for a jig, the hex socket drive grabbed perfectly without any cam-out. All 200 pieces have clean threads and consistent depth, so I didn't have to sort out any duds. Exactly what I needed for precision assembly work.

I needed a solid batch of fasteners for a jig build, and the alloy steel in these screws gives me confidence they won't strip under torque. The hex socket drive engages my Allen key with zero wobble, making assembly quick and frustration-free.
