Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring tight, vibration-resistant connections in precision assemblies
- Enhanced corrosion resistance from the black-oxide finish, extending service life in demanding industrial environments
- High-strength durability with Rockwell C45 hardened alloy steel, resisting wear and deformation under load
- Secure, deep-gripping engagement thanks to the 90° cone point design that bites into materials for reliable positioning
- Easy installation in confined spaces using the compact 0.050" hex drive and headless design
- Precise fine thread spacing (UNF) for smoother adjustment and better load distribution in fine-pitch applications
- Broad regulatory compliance meeting ASME B18.3, RoHS 3, and REACH for safe, globally accepted use
Professional Applications & Engineering Value
This 4-48 UNF set screw is engineered to address critical challenges in precision machinery, electronics, and automotive assemblies where space is limited and vibration loosening is a concern. The black-oxide alloy steel construction provides a protective layer against rust and wear, while the Rockwell C45 hardness ensures the screw maintains its form under repetitive stress. The 90° cone point aggressively engages with shafts or collars, preventing slippage in high-torque applications. Its fine thread spacing and Class 3A thread fit allow for exact adjustments in sensitive equipment, reducing the risk of thread stripping. Ideal for securing gears, pulleys, and knobs, this headless set screw delivers reliable performance in OEM and maintenance settings where precision and durability are paramount.
Specification Summary & Compliance
This set screw adheres to UNF thread standards with a Class 3A thread fit for high precision and tight tolerances. It meets ASME B18.3 specifications (ASTM F912) for dimensional consistency and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use worldwide.
