Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers exceptional engineering value in precision assembly applications where alignment and corrosion resistance are critical. The 1/2" shoulder diameter provides accurate component positioning in machinery, automotive, and aerospace assemblies, while the Class 3A thread fit ensures secure fastening in high-vibration environments. The UNC coarse threads facilitate quick assembly and disassembly, reducing maintenance downtime. With its knurled head texture and hex socket drive, technicians can apply proper torque without slippage, making it ideal for confined spaces in industrial equipment, robotics, and manufacturing fixtures where reliability and precision are paramount.
Specification Summary & Compliance
This shoulder screw features precision 3/8"-16 UNC threads with Class 3A fit for superior thread engagement. The shoulder maintains tight dimensional control with 1/2" diameter (-0.004" to -0.002" tolerance) and 1" length (-0.005" to 0.005" tolerance). Manufactured to ASME B18.3 specifications with material hardness of Rockwell B79. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
