Professional Applications & Engineering Value
This socket head shoulder screw delivers critical engineering solutions where precise rotational alignment and axial positioning are paramount. The 8" shoulder length acts as a sturdy shaft for pulleys, gears, and linkages, eliminating the need for additional bushings. Manufactured from 18-8 Stainless Steel, it resists oxidation and chemical exposure in manufacturing, automation, and outdoor equipment. The 3/8"-16 UNC coarse thread and Class 3A thread fit ensure rapid assembly with high clamp force retention, while the knurled head and hex socket drive prevent tool slippage during high-torque installation. Ideal for machinery, conveyor systems, and precision fixtures, this fastener reduces maintenance downtime and enhances assembly integrity.
Specification Summary & Compliance
This shoulder screw maintains tight dimensional control with a shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". Threads conform to UNC coarse thread standards with Class 3A fit for superior engagement. The product is manufactured in accordance with ASME B18.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
