Customer Reviews (4.6 / 5 · 5 reviews)

Richard ★★★★★

Used these to mount a controller board in a tight enclosure, and the 5/16" length was just right for the job. The aluminum material feels sturdy enough for the weight, and the hex shape made installation simple with a standard wrench.

Owen W. ★★★★★

Had to replace a batch of nylon standoffs that kept stripping, and these #4-40 x 5/16" aluminum ones threaded on clean without any burrs. The 400-count box is a solid deal when you're building a few boards at once, and they hold panels snug without wobble.

Amelia ★★★★★

The aluminum feels sturdy, and these threaded perfectly into my PCB mounting holes without any binding. A full pack of 400 means I won't run out for a while.
