S-94115A583 5/16"-18 x 1" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior vibration resistance with green nylon 6/6 plastic tip that maintains performance across a wide temperature range (-50° to 250° F)
• Exceptional holding power provided by Class 3A thread fit ensuring precise, secure fastening in demanding applications
• Enhanced durability from Black-Oxide Alloy Steel construction with Rockwell C28 hardness for long-lasting performance
• Easy installation and removal with 5/32" hex drive design that prevents slipping and allows for high torque application
• Reliable coarse thread engagement with UNC thread spacing for quick assembly and strong holding capability
• Surface protection from Black-Oxide coating that resists corrosion in industrial environments
• Component protection through soft nylon tip that prevents damage to mating surfaces while maintaining secure positioning

Professional Applications & Engineering Value

This 5/16"-18 UNC set screw delivers critical engineering solutions for industrial applications where vibration resistance and secure positioning are paramount. The Black-Oxide Alloy Steel construction combined with Rockwell C28 hardness ensures reliable performance in high-stress environments, while the headless design with hex drive allows for flush mounting in space-constrained applications. The green nylon 6/6 plastic tip effectively dampens vibrations and prevents loosening in machinery, automotive components, and power transmission systems. Engineered with Class 3A thread fit and coarse thread spacing, this set screw provides rapid installation and maximum clamping force, making it ideal for permanent positioning of gears, pulleys, and collars on shafts where reliability cannot be compromised.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit precision with UNC coarse thread spacing at 5/16"-18 thread size. Manufactured to ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use. The combination of Black-Oxide surface treatment on Alloy Steel with Rockwell C28 hardness provides optimal mechanical properties for demanding fastening applications.
