Customer Reviews (4.2 / 5 · 5 reviews)

Adam J. ★★★★★

The threading is clean and consistent across all 100 pieces, so my standoffs screwed on without any cross-threading hassle. They're light but feel solid enough for holding a panel in place.

Chloe ★★★★★

The threads cut cleanly on all 100 pieces with no burrs, and the aluminum feels solid enough for mounting a small PCB without worrying about flex. I appreciate that the half-inch length gives just the right amount of clearance. Shipping was quick, so I'm set for a while.

Abigail K. ★★★★☆

Used these to mount a small PCB panel and the aluminum finish looks clean against the board. All 100 arrived with uniform threads, though I wish the packaging had a tighter seal for long-term storage.
