Hazel H. ★★★★★

Finally got around to replacing some old bolts on a piece of shop equipment, and these 316 stainless screws threaded in smooth with no binding. The 1"-8 size and partial threading was exactly what I needed for a snug fit against the flange.

Sebastian X. ★★★★★

The partially threaded design made lining up the frame assembly much easier than fully threaded bolts I’ve used before.

Richard ★★★★★

Used these for a heavy equipment frame repair and the 316 stainless held up perfectly against the salt spray. The 1"-8 threads cut cleanly into the tapped holes with no binding. Exactly as described for the price.
