S-92313A433 5/8"-11 x 1 1/2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction
• Exceptional holding power ensured by the Class 3A precision thread fit for minimal backlash
• High-torque installation capability with the 5/16" hex drive, preventing tool slippage
• Enhanced durability and wear resistance from the Rockwell B80 hardness rating
• Reliable, non-slip fastening with the cup point tip that bites into the mating surface
• Simplified assembly in coarse-thread applications with the 5/8"-11 UNC thread form
• Broad industrial compliance meeting ASME B18.3, RoHS 3, and REACH standards

Professional Applications & Engineering Value

This 316 stainless steel set screw is engineered to solve critical challenges in corrosive and high-stress environments. The Class 3A thread fit provides a precise, secure connection that resists vibration-induced loosening in machinery, automotive, and marine components. Its headless, hex drive design allows for flush mounting in confined spaces while enabling high torque application. The coarse UNC threads facilitate quick assembly and disassembly, reducing maintenance downtime. The cup point tip creates a permanent dimple in the shaft, ensuring superior resistance to rotational forces. This combination of corrosion-resistant material and precision engineering delivers long-term reliability in demanding applications where failure is not an option.

Specification Summary & Compliance

This set screw maintains Class 3A thread tolerance per UNC standards with a 5/8"-11 coarse thread configuration. Manufacturing conforms to ASME B18.3 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial applications.
