S-91410A855 3/4"-10 x 5" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with coarse UNC threads and Class 2A fit ensures reliable, vibration-resistant fastening in demanding applications
• Exceptional durability from Rockwell B80 hardened steel construction resists wear and deformation under heavy loads
• Easy installation and removal with external square drive design providing maximum torque transfer without stripping
• Secure component positioning through cup tip design that creates positive engagement and prevents slippage
• Industry-standard compatibility with ASME B18.6.2 specifications guarantees precise dimensional accuracy and performance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Optimal length selection with 5" dimension providing ample engagement for thick assemblies and structural components

Professional Applications & Engineering Value

This 3/4"-10 UNC Square Head Set Screw delivers critical engineering solutions for industrial machinery, heavy equipment, and structural assemblies where vibration resistance and permanent positioning are paramount. The steel construction with Rockwell B80 hardness ensures the screw maintains its clamping force under extreme operational stresses, while the coarse thread spacing provides rapid installation and superior holding power in soft materials or where frequent disassembly isn't required. The external square drive enables high-torque application without cam-out issues, and the cup tip design creates positive indentation in mating surfaces, preventing rotational slippage in pulley systems, gear hubs, and coupling applications. This combination of features addresses common industrial challenges of component creep, alignment maintenance, and fastener integrity in high-vibration environments.

Specification Summary & Compliance

This set screw maintains Class 2A thread fit tolerance for consistent engagement and meets ASME B18.6.2 specifications for dimensional accuracy and performance standards. The UNC coarse thread (3/4"-10) with right-hand direction follows established industrial threading conventions. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and regulatory acceptance for industrial applications worldwide.
