Avery ★★★★★

The binding head sits flush on my panel without cracking, and the slotted drive is easy to torque with a standard driver. Two thousand of these in nylon will outlast any plastic clip I’ve used before.

Miles X. ★★★★★

Honestly, I wasn't sure about nylon for my electronics enclosures, but these #4-40s are rigid enough and the binding head seats nicely without cracking the plastic. A full 2000-count pack means I'll be set for years. The slotted drive is easy to work with and I didn't strip a single one.

Robert M. ★★★★★

These nylon screws worked perfectly for fastening a small plexiglass panel inside a display case. The binding head sits flush and the slotted drive was easy to tighten without stripping the nylon.
