S-95289A679 5/8"-11 x 2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Class 3A thread fit ensuring tight, secure fastening in demanding applications
• Superior corrosion resistance through black oxide coating on alloy steel, extending service life in harsh environments
• Enhanced tip engagement with extended 0.328" tip design providing deeper penetration and superior grip on shafts and components
• High-strength performance backed by Rockwell C45 hardness rating for reliable operation under heavy loads
• Easy installation and removal with 5/16" hex drive allowing efficient torque application in confined spaces
• Industry-standard compatibility through UNC coarse threading (5/8"-11) ensuring broad interchangeability
• 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 critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The black oxide alloy steel construction provides excellent corrosion protection while maintaining the Rockwell C45 hardness needed for high-stress environments. The extended tip design (0.328" length) ensures maximum contact surface area, preventing component slippage in machinery, pulleys, and coupling applications. As a headless set screw with 5/16" hex drive, it offers flush mounting capabilities ideal for rotating assemblies where protruding fasteners would cause interference. The Class 3A thread fit with coarse UNC threading provides superior holding power compared to standard fasteners, making it particularly valuable in heavy equipment, manufacturing machinery, and automotive applications where reliability cannot be compromised.

Specification Summary & Compliance

This set screw features precision Class 3A thread fit with 5/8"-11 UNC coarse threads and right-hand direction. Critical dimensions include 2" length with extended tip measuring 0.328" length (-0.005" to 0" tolerance) and 0.468" diameter (-0.012" to 0" tolerance). Manufactured to ASME B18.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both performance reliability and regulatory adherence for industrial applications.
