S-92311A791 5/8"-11 x 5/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments
• Maximum holding power through the cup point tip design that bites into surfaces for secure, permanent fastening
• Precise thread engagement with Class 3A fit ensuring reliable, vibration-resistant connections in demanding applications
• Enhanced durability from Rockwell B80 hardness, providing excellent wear resistance and long service life
• Easy installation and removal using the 5/16" hex drive, allowing high torque application without head protrusion
• Industry-standard compatibility with UNC coarse threads (5/8"-11) for seamless integration into existing assemblies
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

This 5/8"-11 UNC set screw delivers exceptional engineering value in industrial settings where vibration resistance and permanent positioning are critical. The 18-8 Stainless Steel material provides inherent corrosion resistance, eliminating failure points in moist or chemical-exposed environments. The cup point tip creates concentrated pressure that digs into shaft surfaces, preventing slippage under heavy rotational forces. Combined with the Class 3A thread fit and coarse thread spacing, this hex headless design maintains precise component alignment in machinery, power transmission systems, and manufacturing equipment where reliability is non-negotiable. The right-hand thread direction and 5/16" hex drive ensure compatibility with standard tools while the headless configuration allows flush mounting in space-constrained applications.

Specification Summary & Compliance

This set screw features 5/8"-11 UNC coarse threads with Class 3A thread fit for precision engagement and 0.625" thread diameter. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance standards. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for hazardous substance restrictions.
