Key Features & Benefits at a Glance
- Superior alignment precision with a 4mm shoulder diameter and precise fit for reduced component wear and extended equipment life
- Exceptional durability from Alloy Steel construction and Rockwell B75 hardness, resisting deformation under high-stress conditions
- Reliable coarse threading with 0.5mm pitch and Class 6g fit for faster assembly and secure fastening in industrial applications
- Optimized for confined spaces due to its headless, slotted drive design, allowing installation where clearance is limited
- Guaranteed dimensional consistency meeting DIN 927 standards, ensuring interchangeability and reducing production downtime
- Environmental compliance assurance with RoHS 3 and REACH adherence, supporting sustainable and safe manufacturing practices
- Right-hand thread direction for intuitive installation and compatibility with standard assembly processes
Professional Applications & Engineering Value
This M3 shoulder screw is engineered to solve critical alignment challenges in precision assemblies. The Alloy Steel material and Rockwell B75 hardness provide robust resistance to shear forces and wear, making it ideal for machinery linkages, automotive jigs, and electronic enclosures where exact component positioning is paramount. The 4mm shoulder diameter with precise tolerances acts as a reliable pivot or spacer, eliminating misalignment and reducing vibration-induced failures. With its coarse metric thread and slotted drive, it ensures quick, secure fastening even in high-vibration environments, enhancing assembly efficiency and product reliability for B2B industrial users.
Specification Summary & Compliance
This precision shoulder screw features a Class 6g thread fit per ISO standards, with shoulder diameter tolerance of -0.03mm to 0mm and length tolerance of -0.48mm to 0mm for consistent performance. It conforms to DIN 927 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industry acceptance.
