Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 5-44 UNF Class 3A set screw delivers exceptional performance in machinery, automotive, and precision equipment. The Black-Oxide Alloy Steel material provides a durable barrier against rust and oxidation, crucial for maintaining integrity in humid or corrosive conditions. Its cup tip design concentrates force on a small contact area, preventing rotational slip and ensuring components remain securely positioned. With a fine thread spacing and right-hand thread direction, it offers superior resistance to vibrational loosening, making it ideal for high-stress assemblies. The 1/16" hex drive enables efficient installation even in tight spaces, reducing assembly time while meeting strict ASME B18.3 and ASTM F912 specifications for reliability.

Specification Summary & Compliance

This set screw adheres to Class 3A thread fit tolerances for precise engagement, manufactured in accordance with ASME B18.3 and ASTM F912 standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The product features a UNF thread type with fine spacing, a 1/4" length, and Rockwell C45 hardness for consistent performance in industrial fastening applications.
