Customer Reviews (4.8 / 5 · 5 reviews)

Olivia S. ★★★★★

Installed these in a tight panel assembly where I couldn't access the back side, and the blind clinching feature saved me so much frustration. The stainless steel feels sturdy, and they hold the circuit board securely without any wobble.

Nicholas P. ★★★★★

The blind hole design made alignment on my panel a breeze—no need to worry about threads poking through the back. These stainless standoffs feel solid and hold my board securely without any wobble.

George G. ★★★★★

Installed these to secure a PCB in a tight enclosure, and the blind threads saved me from worrying about debris on the back side. Each standoff seated firmly with a standard press tool, and the 50-pack gives plenty of spares.
