Customer Reviews (5.0 / 5 · 5 reviews)

Brian ★★★★★

These little screws fit perfectly into the mounting holes on my metal enclosure panels. The truss head sits flush and the stainless steel feels solid, no rust issues after a week in a damp garage.

Matthew ★★★★★

Lost a few trying to extract a stripped one from a tight panel, but once I added a drop of lube they drove perfectly. The truss head sits flush and the stainless steel feels solid for outdoor gear.

Jason ★★★★★

Exactly what I needed for mounting a small electronic enclosure. The 18/8 stainless steel gives me confidence they won't rust, and the threads cut cleanly without binding.
