Customer Reviews (4.8 / 5 · 5 reviews)

Ryan T. ★★★★★

I needed a full thousand for a jig I’m building, and these #0-80 screws came perfectly deburred—no burrs to fight with. The short 5/16" length is ideal for thin panels, and the 18/8 stainless gives them a nice weight.

William ★★★★★

Finally, a #0-80 screw that doesn't strip when I torque it down for my jig assembly. The hex socket drive engages cleanly every time, and the 18/8 stainless finish looks professional.

Jason ★★★★★

These #0-80 screws are perfect for my hobby jigs, and the 18/8 stainless steel gives me confidence they won't rust over time. The hex socket drive makes installing them in tight spaces much easier than using a tiny flathead.
