Key Features & Benefits at a Glance
- Superior corrosion resistance with Black-Oxide coating, extending service life in harsh industrial environments.
- High-strength alloy steel construction with Rockwell C45 hardness ensures reliable, long-term holding power without deformation.
- Precise Class 3A thread fit provides tighter tolerances for secure fastening and reduced risk of loosening under vibration.
- Headless hex drive design (5/64") allows for flush installation in confined spaces, improving assembly aesthetics and safety.
- Cup tip configuration offers excellent grip on shafts and components, minimizing slippage and ensuring accurate positioning.
- Fine thread spacing (UNF) delivers enhanced adjustment control and resistance to vibrational loosening in dynamic applications.
- Compliance with ASME B18.3, RoHS 3, and REACH guarantees consistent quality, environmental safety, and regulatory acceptance.
Professional Applications & Engineering Value
This 8-36 UNF Class 3A set screw is engineered to address common industrial challenges such as component slippage, corrosion-induced failure, and space constraints. Made from high-strength alloy steel and treated with a Black-Oxide surface finish, it resists rust and wear in demanding settings like machinery, automotive assemblies, and precision instruments. The headless hex drive and fine thread spacing enable secure, flush mounting in tight areas, while the cup tip design ensures firm contact on shafts or gears, reducing maintenance needs and enhancing operational reliability. Ideal for applications requiring repeated adjustments and high vibrational resistance, this screw provides lasting performance in industrial set screw systems.
Specification Summary & Compliance
This set screw features a Class 3A thread fit for precise dimensional accuracy, adhering to UNF fine thread standards with specifications meeting ASME B18.3 (ASTM F912). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and regulatory acceptance in global markets.
