Victoria ★★★★★

I'm building a small jig and these 1/4-28 hex heads grabbed perfectly with my socket wrench—no stripping. The yellow zinc finish feels durable and the full threading made adjusting depth a breeze.

Sebastian L. ★★★★★

I had to replace a stripped bolt on my milling machine, and these grade 5 screws fit perfectly without any wobble. The yellow zinc coating looks clean and should resist rust in the shop.

Timothy ★★★★★

These are exactly what I needed for a jig I’m building—the hex head grabs my socket wrench perfectly without stripping. The yellow zinc coating looks durable and should resist rust in my shop. A full 300-count package means I’ve got plenty left over for future projects.
