Sofia C. ★★★★★

The partial threading made all the difference on a heavy-duty bracket I was bolting together—no wasted space in the threads. The yellow zinc finish looks clean and hasn’t shown any rust even after a few days in my damp garage.

Henry ★★★★★

Worked perfectly for a jig I was building—the hex head grabbed my socket without slipping, and the yellow zinc finish looks clean.

Claire N. ★★★★★

The partial threading makes these hex head cap screws a solid choice for clamping applications where you need the threaded portion to stop at a specific depth. Hardened to Grade 5 with the yellow zinc coating, they've held up well against mild rust in my shop environment.
