P515-M06-F13-440 | فواصل يونيكورب #4-40 (100/عبوة)

The perfect height for keeping my PCB off the mounting surface, and the #4-40 threads engage smoothly without any binding. I’ve already used half the bag on a couple of projects and they hold firm.

The threads are crisp and consistent, making installation on my circuit board panel much smoother than with generic standoffs. They hold the board securely with no wobble at all.

Finally got around to mounting a small PCB with these and the #4-40 threads seated perfectly into the board holes without any galling. The 100-pack gives me plenty of spares for future panel spacing jobs, and they feel solidly machined for the price.
