- High-strength performance with a tensile strength of 70,000 psi and Rockwell B55 hardness for reliable load-bearing applications.
- Secure and flush fastening with the low-profile socket head, saving space and preventing snagging.
- Consistent and reliable threading ensured by the Class 6g thread fit and coarse M8x1.25 pitch for easier assembly.
- Compliance with international standards including DIN 923, guaranteeing dimensional interchangeability and quality.
- Safe for regulated industries with full RoHS 3 and REACH compliance, meeting environmental and safety directives.
Professional Applications & Engineering Value
This M8x1.25 shoulder screw is engineered to solve critical alignment and wear challenges in precision industrial applications. The unthreaded 10mm shoulder diameter acts as a precise pivot, bearing surface, or locator for gears, linkages, and rotating assemblies, eliminating the need for separate spacers or bushings and reducing component count. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to rust and corrosion, ensuring long-term reliability in demanding conditions. The low-profile socket head offers a compact design for space-constrained applications while providing a positive drive. Combined with the Class 6g thread fit, it ensures vibration resistance and secure fastening, making it an indispensable component in machinery, automation, and electronic enclosures.
Specification Summary & Compliance
This precision shoulder screw adheres to the DIN 923 standard. Key dimensional specifications include an M8x1.25 coarse thread with a Class 6g tolerance, a shoulder diameter of 10 mm (tolerance: -0.036 to 0 mm), and a shoulder length of 10 mm (tolerance: 0.07 to 0.15 mm). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
