Customer Reviews (4.8 / 5 · 5 reviews)

Ryan ★★★★★

Repairing a stripped thread on a machinery housing felt hopeless until I tried these inserts, and the 304 stainless steel holds up perfectly under repeated bolt tightening. The helical design bites into the aluminum cleanly, and the 100-pack means I’ve got spares for every future job.

Andrew ★★★★★

Used a few of these to repair stripped threads on an engine block, and the 304 stainless steel held up perfectly under torque. The 100-pack is great value for anyone doing general fastening work.

Elizabeth ★★★★★

Installing these was way smoother than the cheap brands I've used before—the 304 stainless steel feels solid and the threading caught perfectly on the first try. For a hundred-pack at this quality, it’s a no-brainer for any general fastening work.
