S-93339A239 M12 x 27 mm Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power from Rockwell C39 hardened alloy steel construction, resisting wear and deformation under heavy loads
• Precise and secure positioning with the ball tip design, minimizing surface damage and providing positive engagement
• High-strength fastening for demanding applications thanks to the robust M12 coarse thread (1.75mm pitch) and Class 6g thread fit for reliable assembly
• Streamlined installation and removal using a standard 6mm hex key, ideal for confined spaces due to its headless design
• Superior corrosion resistance and material integrity from the hardened alloy steel, ensuring long-term performance
• Compliance with major environmental regulations, being RoHS 3 compliant for use in regulated industries
• Versatile right-hand thread for standard industrial assembly processes, ensuring broad compatibility

Professional Applications & Engineering Value

This M12 set screw is engineered to solve critical challenges in industrial machinery, automotive components, and precision equipment where vibration resistance and positional security are paramount. The alloy steel material, hardened to Rockwell C39, provides the necessary shear strength and durability to prevent loosening under dynamic loads. The ball tip offers a significant engineering advantage by concentrating force on a small area, creating a precise dimple for secure location without the risk of slippage that can occur with flat or cup points. This design is particularly valuable in shaft collars, gears, and pulleys, ensuring components remain in exact alignment. The coarse thread (1.75mm pitch) allows for faster installation and greater holding power in softer materials or where high vibration is present, making this hex headless screw a reliable, heavy-duty fastening solution.

Specification Summary & Compliance

This metric set screw conforms to a Class 6g thread fit for precise dimensional accuracy and assembly consistency. The manufacturing adheres to standard metric thread specifications for the M12x1.75mm coarse thread profile. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead as an alloying element in steel, ensuring it meets stringent environmental regulations for industrial use.
