S-93339A257 M12 x 18 mm Set Screws

Key Features & Benefits at a Glance

• Superior holding power thanks to the ball tip design that creates secure, concentrated contact points
• Exceptional durability and wear resistance from Rockwell C39 hardness, extending service life in demanding applications
• Reliable, coarse thread engagement with Class 6g fit for faster assembly and vibration resistance
• Streamlined installation in confined spaces using the 6mm hex drive and headless design
• High-strength performance from alloy steel construction for heavy-duty fastening requirements
• Broad industrial compatibility with right-hand metric threading (M12 x 1.75mm)
• Environmentally responsible manufacturing with RoHS 3 compliance for regulated industries

Professional Applications & Engineering Value

This M12 set screw is engineered to solve critical industrial fastening challenges where space is limited and vibration is a concern. The headless design and 6mm hex drive allow for installation in tight assemblies, while the ball tip concentrates force for superior grip on shafts and collars, preventing slippage. Manufactured from hardened alloy steel to Rockwell C39, it withstands high stress and repetitive loads in machinery, automotive, and manufacturing equipment. The coarse 1.75mm pitch and Class 6g thread fit ensure quick, secure engagement, reducing assembly time and maintenance needs in production environments.

Specification Summary & Compliance

This metric set screw features M12 x 1.75mm coarse threading with Class 6g tolerance for precision fit. It is manufactured from alloy steel, hardened to Rockwell C39, and complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as an alloying element in steel.
