Customer Reviews (4.8 / 5 · 5 reviews)

David ★★★★★

The red nylon patch on these screws is a nice touch—holds them securely in place without needing a separate locking compound. They fit perfectly into the precision assembly I’m working on, and the hex drive made installation smooth.

Sebastian ★★★★★

I needed a reliable fastener for a jig I’m building, and the hex socket drive made these much easier to tighten in tight spots than a slotted screw. The 18/8 stainless steel also feels sturdy and corrosion-resistant right out of the box.

Ellie D. ★★★★★

The red patch locking compound on these #4-40 screws saves me from having to apply thread locker on each one during assembly, which is a huge time saver. They fit perfectly in our jigs and the 18/8 stainless seems like it'll hold up well.
