Customer Reviews (5.0 / 5 · 5 reviews)

Sebastian ★★★★★

The partial threading on these 1"-8 cap screws made installation into my equipment frame much easier than fully threaded bolts. They gripped tight with a socket wrench and the yellow zinc finish looks clean.

Brian ★★★★★

These are solidly built Grade 5 bolts—the yellow zinc coating looks even and clean, and the partial threading grabbed perfectly when I torqued them down with a socket. The 4-1/2" length was exactly right for the flange I was joining.

Henry U. ★★★★★

Used these to bolt down a heavy press in the shop—the Grade 5 yellow zinc held up perfectly under torque without stripping. The hex head gave my socket a solid bite, even in a tight spot.
