Customer Reviews (4.8 / 5 · 5 reviews)

Chloe M. ★★★★★

I tightened these onto a milling fixture and the black oxide finish survived a spray of coolant without a single rust spot. The hex socket drive gave me solid torque without stripping.

Leo ★★★★★

The nylon patch is a lifesaver—these held tight on my milling fixture through a full shift without a single one backing out. The black oxide finish also gave them a clean, uniform look straight out of the pack.

Sophia ★★★★★

Used these for a jig I was building and the nylon patch is a nice bonus — holds tight without any liquid threadlocker. The black oxide finish looks clean and should resist rust well in my shop.
