Nicholas Y. ★★★★★

Perfect for mounting lightweight panels in tight spots where I don't want metal fasteners to corrode. The nylon material is non-conductive, which saved me from shorting a circuit board. They thread smoothly into standard #4-40 tapped holes.

Benjamin ★★★★★

Finally got around to mounting a PCB panel and these nylon screws were exactly what I needed—the flat 100° head sits flush in a countersink so nothing snags. The slotted drive is a bit fiddly with a screwdriver but once seated they hold tight without any conductivity worries.

Thomas ★★★★★

I needed non-conductive fasteners for a circuit board mount, and these nylon screws work perfectly. The slotted drive made installation easy with a standard screwdriver, and the 100° flat head sits flush without any wobble.
