Stella B. ★★★★★

Took a chance on a full box of these for a big assembly run and they didn’t disappoint—the 304 stainless holds up without any corrosion worries. Each insert threads in cleanly, no binding on the tap, and the 1000 count means I’m set for months. Solid purchase for general fastening work.

Matthew M. ★★★★★

Ordered a box of 1000 for a repair run at the shop and the 304 stainless steel feels solid, no burrs on the threads straight out of the pack. They seated cleanly into the tapped holes without any binding, which saved me a good chunk of time. Exactly what I needed for general assembly work.

Timothy D. ★★★★★

These things are built like a tank, the 304 stainless steel feels seriously solid for general assembly work. Having a full thousand of them means I won’t be running out for a long time, and they thread in cleanly without any snags.
