Customer Reviews (4.8 / 5 · 5 reviews)

Sophia ★★★★★

The black oxide finish on these bolts has held up perfectly against oil and chips in my milling machine setup. The hex socket engaged cleanly with my Allen wrench, no wobble or stripping at all.

Sophia ★★★★★

Installed these in a jig for a production run and the hex socket drive engaged perfectly every time with no stripping. The fully threaded length gave me plenty of grip for the heavy load, and the black oxide finish looks clean and professional.

Richard ★★★★★

Started replacing some standard bolts on my shop jig and these hex socket drives made installation so much easier. The black oxide finish looks great and they fit perfectly at 3/8-24 x 3 inches.
