Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in demanding industrial environments.
- Exceptional holding power ensured by Class 3A thread fit, providing precise, vibration-resistant fastening for critical assemblies.
- High-strength durability with Rockwell C45 hardness, resisting wear and deformation under heavy loads.
- Secure, flush installation thanks to the headless hex drive design, ideal for confined spaces and rotating components.
- Easy, tool-friendly engagement with a 5/64" hex drive and coarse UNC threads, speeding up assembly and reducing installation errors.
- Gentle surface contact from the oval tip, minimizing damage to shafts and components while maintaining firm positioning.
- Global compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for reliable, safe use in regulated industries.
Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to address common industrial challenges like component slippage and vibration-induced loosening. The black-oxide alloy steel construction provides a robust barrier against rust and wear, while the Class 3A thread fit and coarse thread spacing ensure tight, reliable clamping in machinery, automotive, and electronics assemblies. Its headless design with a 5/64" hex drive allows for unobtrusive installation in tight spaces, and the oval tip distributes pressure evenly to prevent marring of precision parts. Ideal for securing gears, pulleys, and collars, this screw delivers consistent performance where high-strength and vibration resistance are critical.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including UNC thread type, 8-32 thread size, and Class 3A thread fit for superior accuracy. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe, sustainable use in global markets.
