Customer Reviews (4.8 / 5 · 5 reviews)

Adam ★★★★★

The partially threaded design made alignment in my jig much easier, and the black oxide finish looks sharp against the steel. These 140mm screws seated cleanly with the hex drive, no stripping even torqued down hard. Solid choice for machinery work.

Michael ★★★★★

These screws are perfect for my jig fixture build, the partial threading gave me just the right grip depth. The black oxide finish feels nicely durable and hasn't chipped during installation.

Daniel A. ★★★★★

The hex socket drive seated perfectly on my torque wrench, and the black oxide finish looks sharp on my jig setup. Partially threaded 140mm length gave me just the right grip for a heavy machinery bracket. These are holding up great so far.
