The hole of small diameter hex socket set screws can all too easily crack when the screw is being tightened. Our hex socket set screws are made of Ni-Cr-Mo Steel (JIS SNCM240). Furthermore, the manufacture is high-precision.

Click here for more information of Ni-Cr-Mo Steel.

Through heat treatment, we have made the hardness to be high on Rockwell Scale C (HRC50 - 53) as well as coferring high durability. The hexagonal hole is as tough as you can handle, and if your hexagonal bar spanner gets stuck during overtightening because the handle snaps (see the diagram below), it can be removed by magnet, because the hexagonal hole of our hex socket set screws does not deform.

For rustproofing, our hex socket set screws are surface treated with a black oxide finish and then dried with a hot air vacuum dryer. These screws will thus be suitable for automated assembly because they need not be oiled; at the very least your assembly workers need not get oily hands.
