Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty equipment. The Class 3A thread fit and coarse 10-24 UNC thread provide secure fastening in high-vibration environments, reducing the risk of loosening. The knurled socket head with hex drive ensures easy installation and removal, even in confined spaces. Its corrosion-resistant properties make it suitable for marine, chemical processing, and food industry applications where moisture and chemicals are present. The precision shoulder acts as a reliable pivot or spacer in assemblies, maintaining alignment and reducing wear on moving parts.
Specification Summary & Compliance
