Customer Reviews (4.6 / 5 · 5 reviews)

Violet U. ★★★★★

Threaded right up to the shoulder without any binding, even on a tight fit with a socket, and the zinc plating still looks clean after a week of outdoor use. Solid grip for heavy equipment assembly.

Hannah ★★★★★

The hex head on these cap screws grabs perfectly with a socket, and the zinc plating looks clean and even across all 200. I’m halfway through assembling a press frame, and every thread has engaged smoothly without any binding.

Joseph ★★★★★

The partially threaded design made installation into my equipment frame much easier than fully threaded bolts would have. These grade 8 bolts feel solid and the zinc plating looks clean. A great value for a bulk pack.
