Customer Reviews (4.6 / 5 · 5 reviews)

Henry E. ★★★★★

The black oxide finish on these screws resists rust perfectly in my humid basement workshop, and the hex socket drives cleanly without stripping even under torque. Threads are sharp and consistent through the whole pack, saving me from wasted time sorting duds.

Chloe A. ★★★★★

Used a handful of these in a tiny jig I machined last weekend, and the #3-48 thread fit cleanly into pre-tapped holes without any binding. The socket drive grabbed firmly with a hex key, and the thermal black oxide finish looks consistent across the whole pack of 100.

Zoe ★★★★★

The black oxide coating on these screws is much more consistent than I’ve seen on other packs, so they look clean in my tooling fixture. Each one seated perfectly with a hex driver, and at 100 pieces this pack will last me through several small assembly jobs.
