Customer Reviews (4.6 / 5 · 5 reviews)

Stella ★★★★★

Threads are clean and fully cut, so they grabbed perfectly into my jig plate without any galling. The zinc coating looks even and should hold up fine in the shop. These will definitely be my go-to for tooling builds now.

Ella ★★★★★

The hex socket drive on these fit my torque wrench perfectly, and the zinc plating looks clean and durable on my tooling setup. For M20 hardware, the 40mm length was exactly what the precision assembly needed.

Thomas ★★★★★

Used these on a jig I was building, and the hex socket drive made installation quick with an Allen key. The zinc plating seems durable so far, and the 25-pack is great value for the price.
