Grace O. ★★★★★

The nylon pellet tips hold firmly without marring the surface, and the alloy steel body feels sturdy during installation. Perfect for securing a small jig fixture on my drill press table.

Samuel N. ★★★★★

The hex socket drive made adjusting these in a tight spot on my milling fixture much easier than a standard slotted screw. I appreciate how the nylon pellet cup point holds without marring the surface, and the alloy steel feels sturdy for the price.

Sofia ★★★★★

Installed these in a small jig where standard hex heads would have been too tall. The cup point sits perfectly flush, and the nylon patch on the threads holds fast without any extra Loctite.
