Emma V. ★★★★★

Installed a bunch of these into some mild steel brackets for a repair job and they cut clean threads every time without spinning. The 100-count pack is great value for keeping on hand, and the imperial sizing matched my existing hardware perfectly.

Brian ★★★★★

Had a stripped hole in an aluminum bracket and these mil-spec inserts saved the repair. The imperial sizing matched my tap perfectly, and the 100-count box means I've got plenty left for future jobs.

Zoe ★★★★★

These things are stupidly easy to install, and having a hundred in one box means I never have to ration them for a project again. The imperial sizing is spot on, which saved me from having to re-tap any holes.
