Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications.
- Superior wear and corrosion resistance thanks to the Black-Oxide finish on Alloy Steel and a Rockwell C45 hardness rating.
- Secure and tamper-resistant installation enabled by the headless design and 5/64" hex drive, ideal for confined spaces.
- Reliable engagement and minimal component damage from the cup point tip, which bites into the shaft for a positive grip.
- Broad compatibility and easy assembly with standard 8-32 UNC coarse threads and right-hand direction.
- Guaranteed quality and material integrity as it meets the stringent dimensional and material specifications of ASME B18.3.
- Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental standards.
Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to solve critical challenges in industrial assembly and machinery. The Black-Oxide Alloy Steel construction provides a durable barrier against rust and wear, extending the component's life in harsh environments. The headless design and hex drive allow for installation in tight spaces where a protruding head is not feasible, making it ideal for securing collars, gears, and pulleys onto shafts. The cup point creates a concentrated contact area, digging into the shaft material to prevent slippage and resist loosening under high vibrational loads. This combination of Class 3A thread fit and robust material ensures a reliable, permanent set that maintains alignment and torque in precision equipment, automotive systems, and heavy machinery.
Specification Summary & Compliance
This set screw features a precise 8-32 UNC coarse thread with a Class 3A fit for superior dimensional accuracy and engagement. It is manufactured in compliance with the ASME B18.3 standard, ensuring consistent quality and performance. The product is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental regulations for hazardous substances.
