Christopher ★★★★★

I bought these for a jig I was building, and the hex socket drive made installation much easier than a standard slotted screw. The black oxide finish looks great and seems durable for workshop use.

Joseph ★★★★★

The nylon pellet in these is the unsung hero—it locks the thread tight without needing any threadlocker, and the black oxide finish has held up great through three days of assembly work. They seat flush in my tooling plates with zero wobble, and the hex socket drives cleanly every time.

Jason Y. ★★★★★

The black oxide finish on these screws has held up really well through several assembly and disassembly cycles in my shop, no rust or wear so far. The nylon pellet locking feature is a nice touch too, they stay put even under vibration.
