Customer Reviews (4.4 / 5 · 5 reviews)

Jason S. ★★★★★

The hex heads on these screws grabbed my socket perfectly without any slippage, making installation quick. The yellow zinc coating looks consistent and seems durable for my shop equipment. Exactly the length I needed for a machinery guard.

Samuel ★★★★★

The threads grabbed clean and the yellow zinc finish looks solid under the shop lights, no rust spots after a week of outdoor use on my trailer hitch. These 3/4-10s are hefty enough that I didn't snap one torquing them down with a breaker bar.

Andrew ★★★★★

The partially threaded design made these hex head cap screws perfect for a machinery alignment job where I needed grip without full threading. The grade 5 steel feels solid and the yellow zinc finish looks clean. Exactly what I needed for a reliable industrial fastening.
