Alexander W. ★★★★★

Needed a precise fastener for a small jig project, and the partially threaded design gave me just the grip I needed without bottoming out. Fit perfectly in my hex driver, and the 18/8 stainless should hold up well in my shop.

Grace ★★★★★

The threading on these #4-40s is clean and consistent across all 600 pieces, which saved me a ton of time at the bench. I’ve already used them in a couple of precision jigs and the hex socket drive bites perfectly with my Allen key.

Eli ★★★★★

I needed a solid batch of 18/8 stainless screws for a jig I’m building, and these #4-40 x 1-3/4" partially threaded ones fit perfectly without stripping.
