Customer Reviews (4.2 / 5 · 5 reviews)

George ★★★★★

Perfect for my CNC fixture plate, the flat head seats flush without any interference and the hex socket drive made install quick even in tight spots. Zinc plating seems durable so far, and the 12.9 hardness gives me confidence these won't strip out under heavy clamping loads.

Richard T. ★★★★★

Used a full 200-pack on a jig build and only one had any thread burr worth filing. The partial threading is exactly 20mm, which made depth stops predictable in the drill press.

Timothy P. ★★★★★

These are the right length for my jigs and fixtures, and the zinc plating keeps them from rusting in my shop. The hex socket drive seated perfectly with my Allen key, and the class 12.9 alloy steel feels plenty solid for the torque I put on them.
