Jacob M. ★★★★★

I needed a small batch for a jig I’m building, and these M2s fit the precision assembly specs perfectly. The hex drive seats flush, and the 400-count package leaves plenty for spares.

Adam W. ★★★★★

The black oxide finish on these little screws is holding up great during my jig assembly work. Nice that the hex drive lets me torque them precisely without stripping.

George ★★★★★

I needed exactly these M2-0.4 x 4mm screws for a small jig I'm building, and the 400-piece pack means I won't run out anytime soon. The hex socket drive makes them easy to install even in tight spaces.
