Customer Reviews (4.6 / 5 · 5 reviews)

Elizabeth L. ★★★★★

These clinch nuts seated perfectly flush in the sheet metal panel I was working on, and the steel threads felt solid when I tested them with a #4-40 screw. The 100-pack was exactly what I needed for the job.

Miles ★★★★★

Pressed them into some 16-gauge steel brackets with an arbor press and they seated flush without any distortion. The threads were clean and the #4-40 screws spun in smoothly every time. Exactly what I needed for a hundred fastening points.

Steven ★★★★★

The hex shape on these clinch nuts makes them easy to insert into sheet metal, and they held firmly when I torqued down a #4-40 screw. I used up the whole bag on a control panel project and every single one seated perfectly without spinning.
