Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical alignment and durability challenges in industrial fastening. The Class 3A UNF fine thread provides superior clamping force and vibration resistance, ideal for precision equipment like robotic arms, conveyor systems, and pivoting mechanisms. The black oxide finish adds a protective layer against rust and wear, while the knurled socket head ensures firm grip during installation, reducing slippage in high-torque scenarios. With a 3/4" shoulder diameter and precise tolerances, it maintains exact positioning in bearings and linkages, minimizing play and extending component life in demanding applications.
Specification Summary & Compliance
This shoulder screw adheres to UNF thread standards with Class 3A fit for high precision. Shoulder dimensions include a diameter of 3/4" (tolerance: -0.004" to -0.002") and length of 7/16" (tolerance: -0.005" to 0.005"), ensuring consistent performance. It is manufactured from alloy steel hardened to Rockwell C32 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and environmentally responsible use.
