Hexagon socket set screws

Small-diameter hex socket set screws are typically vulnerable to stripping or cracking when tightened firmly with a hex key.

This can lead to installation issues, costly downtime, and difficult maintenance.Our hex socket set screws are engineered to eliminate these concerns. Manufactured with high-precision hex socket geometry and made from premium nickel-chromium-molybdenum steel (SNCM240), our screws undergo advanced heat treatment to achieve a hardness of HRC 50-53-while maintaining excellent toughness.

The result? Even when tightened to the extreme-up to the point where the hex key itself fractures-the hex socket remains intact. No stripping. No cracking. No deformation. An additional advantage:because the socket maintains its precise shape, if a hex key tip should break inside, simply bring a magnet close to the socket. The broken fragment will be magnetically attracted and can be easily removed. 

After black oxide treatment, our hex socket set screws are dried in a vacuum hot-air dryer to remove excess anti-corrosion oil.This means:No oil on workers' hands during assembly. Easy use in automated assembly systems. Excellent corrosion resistance. Clean, efficient, and reliable.
