Metric Precision Hex Socket Shoulder Bolts

Product Description

Precision Shoulder Bolts (Shoulder Screws) Manufactured from high-grade alloy steel and finished with precision grinding processes, our shoulder bolts feature a shoulder diameter tolerance maintained within the h7 class. This ensures exceptional axial positioning accuracy and superior surface smoothness. The internal hex socket head supports high-torque fastening, while the precision-ground shoulder acts as a reliable axle or locating pin, delivering a dual function of secure fastening and precise guidance.

Industry Applications

Widely utilized in precision stamping dies, semiconductor packaging equipment, automated robotic arms, and medical instruments. It is specifically engineered for linkage mechanisms requiring frequent reciprocating motion, tight oscillation clearance, and stringent repeatability. These bolts are essential base components for achieving high-precision assembly in modern smart manufacturing.
