Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers exceptional engineering value in precision mechanical systems where corrosion resistance and dimensional accuracy are critical. The 2" shoulder length with tight diameter tolerance provides precise bearing surfaces for rotating components, eliminating the need for separate spacers in machinery assemblies. The Class 3A UNC thread fit ensures reliable fastening in high-vibration industrial equipment, while the knurled socket head with 1/4" hex drive facilitates secure installation in confined spaces. Engineered to ASME B18.3 standards, these shoulder screws are ideal for precision manufacturing equipment, conveyor systems, and automated machinery where corrosion-resistant fasteners must maintain dimensional stability under continuous operational stress.
Specification Summary & Compliance
This precision shoulder screw features 3/8"-16 UNC coarse threads with Class 3A fit for superior thread engagement. The shoulder maintains tight dimensional control with diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". Manufactured to ASME B18.3 specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring both mechanical precision and regulatory acceptance for industrial applications worldwide.
