Samuel X. ★★★★★

Pulled these out of the box and the hex socket drive seated perfectly on my Allen key—no wobble at all. The alloy steel feels dense and solid, and all 100 threads were clean with zero burrs on the first pass. My jig’s holding together exactly as it should.

Eli ★★★★★

Exactly the right length for my fixture plates, and the alloy steel takes a beating without rounding out the hex socket. Threads were clean right out of the box, no chasing needed on any of the hundred.

Jason ★★★★☆

Needed a batch of flat head socket screws for a jig I’m building, and these alloy steel ones feel solid in hand. The hex drive seated cleanly without stripping, though I wish the countersink angle was listed on the package. Still, for precision assemblies, they’ve been exactly what I needed.
