Nicholas ★★★★★

Exactly the right size for replacing a stripped screw on my bench top machine, and the socket head made installation with an Allen key simple. It fit perfectly into the M4x12 threading without any wobble.

Jacob ★★★★★

Got these as the exact part for my lathe's cross slide and they threaded in cleanly with no wobble. The socket head lets me get a hex wrench in tight spots, which is a lifesaver when you're working behind the chuck.

Andrew E. ★★★★★

Perfect fit for my SC4 lathe’s cross slide; the 12mm length threaded smoothly into the existing hole without any binding. Much better than the generic hardware I tried before.
