• Compliance with major industry standards including ASME B18.2.1, RoHS 3, and REACH

Professional Applications & Engineering Value

This 5/8"-11 UNC Hex Head Screw in 316 Stainless Steel is engineered to solve critical fastening challenges in corrosive and high-stress environments. Its coarse thread (UNC) and partial threading provide excellent grip and reduce the risk of thread stripping in softer materials or when repeated disassembly is required. The external hex drive allows for high-torque application, making it ideal for heavy-duty industrial applications such as construction, marine equipment, chemical processing plants, and offshore structures where corrosion-resistant fasteners are non-negotiable. The combination of high tensile strength and material integrity ensures a reliable, long-lasting connection that minimizes maintenance and replacement costs.

Specification Summary & Compliance

This screw features a Class 2A thread fit for consistent assembly and a 2" length with a minimum thread length of 1 1/2". It is manufactured to meet ASME B18.2.1 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated markets.
