Customer Reviews (4.8 / 5 · 5 reviews)

Thomas ★★★★★

The Phillips heads grip the driver beautifully—no camming out even when I’m zipping them into tight spots. Pan washer heads really do spread the load, and with 2,000 in a package, I’ll have these for a decade.

Eli X. ★★★★★

Finally got these in for a project requiring precise load distribution, and the pan washer head really makes installation smoother than fiddling with separate washers. The 18-8 stainless feels sturdy enough for outdoor use, and having 2000 pieces means I won't run out anytime soon.

Abigail ★★★★★

Switched to these from plain #4-40 washers and separate screws—the pre-assembled head saves a ton of time on panel assembly. The 18-8 stainless feels solid, and having a full 2000-count box means I won't run out mid-project.
