Customer Reviews (5.0 / 5 · 5 reviews)

Jacob ★★★★★

Came out of the box with a nice even black oxide finish and the nylon pellet held tight when I set them into my jig. Sockets were clean, no burrs on the threads, and all 100 matched up perfectly.

Kevin ★★★★★

These are exactly what I needed for a jig I’m building, and the black oxide finish looks clean and professional. The hex socket drive made installation straightforward with my Allen key, and they hold tight.

Jason ★★★★★

The nylon pellet locking feature really impressed me—holds tight even after removing and reinstalling them a few times on my jig build. The black oxide finish also gives them a nice, consistent look against the tool steel.
