Key Features & Benefits at a Glance
- Superior holding power thanks to the ball tip design that creates positive locking and prevents component slippage in demanding applications
- Exceptional durability and wear resistance provided by the alloy steel construction hardened to Rockwell C39
- Reliable and secure installation with the 6mm hex drive, offering high torque transmission and reducing the risk of tool slippage
- Wide compatibility and easy assembly with the M12 coarse (1.75mm pitch) thread conforming to Class 6g fit for standard metric components
- Optimized for high-vibration environments due to the headless, flush-mount design that maintains a secure, low-profile connection
- Safe for regulated industries as it is RoHS 3 compliant, meeting environmental standards for industrial use
- Precision-engineered tip with an 8.5mm diameter ball made from alloy steel for consistent, repeatable positioning
Professional Applications & Engineering Value
This M12 alloy steel set screw is engineered to solve critical challenges in industrial assembly and machinery. The ball tip ensures concentrated point contact, effectively securing pulleys, gears, and collars on shafts without damaging the mating surface. Its Class 6g thread fit and coarse 1.75mm pitch provide excellent engagement and resistance to loosening under dynamic loads and vibration, common in automotive, manufacturing, and heavy equipment. Manufactured from hardened alloy steel and featuring a 6mm hex drive, it delivers the strength needed for high-stress applications while allowing for easy installation and removal with standard tools, reducing maintenance downtime and improving operational reliability.
Specification Summary & Compliance
This set screw adheres to metric (M12 x 1.75mm) coarse threading standards with a Class 6g thread fit for precise dimensional accuracy. It is manufactured from alloy steel and hardened to Rockwell C39 for consistent performance. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(a) for lead as an alloying element in steel, ensuring it meets environmental regulations for industrial fasteners.
