Customer Reviews (5.0 / 5 · 5 reviews)

Aurora ★★★★★

Every single one of these came out of the box with a clean, uniform black oxide finish and threads that spun smoothly into my fixture plates without any binding. I’ve already used about half the pack on a couple of tooling jigs and they’re holding torque perfectly under repeated disassembly.

Lucy ★★★★★

I needed a solid batch for jig repairs, and these M8 button heads fit perfectly with no stripped threads. The Class 10.9 alloy steel feels tough out of the package.

Samuel ★★★★★

The hex socket drive made it easy to install these in tight spaces on my welding fixture. The black oxide finish seems durable so far, and the full threading held strongly in the tapped holes. Exactly what I needed for a clean, secure assembly.
