Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction and black oxide finish, ideal for harsh industrial environments.
- Precise component alignment ensured by the 20mm shoulder with controlled diameter tolerance for stable assembly fit.
- High load-bearing capacity with 70,000 psi tensile strength and 45,000 psi minimum shear strength for demanding applications.
- Secure, tool-friendly installation via the 5mm hex socket drive and knurled 16mm head, preventing slippage during tightening.
- Reliable thread engagement with Class 5g6g fit and M6x1mm coarse pitch, enabling quick assembly and vibration resistance.
- Enhanced durability from Rockwell B83 hardness, maintaining structural integrity under repeated stress.
- Global compliance assurance meeting ISO 7379 standards and RoHS 3/REACH regulations for safe, international use.
Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 20mm shoulder length provides a stable bearing surface for rotating parts like gears and pulleys, reducing eccentric movement and extending component life. Manufactured from 18-8 stainless steel with a black oxide finish, it resists oxidation and chemical exposure in automotive, machinery, and electronics sectors. The knurled head enhances grip for manual adjustments, while the hex socket drive ensures high torque application without stripping. Ideal for jigs, pivots, and linkages, this screw delivers consistent performance where corrosion resistance and dimensional accuracy are paramount.
Specification Summary & Compliance
The screw adheres to ISO 7379 for dimensional consistency, with Class 5g6g thread fit ensuring precise tolerance. Shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, guaranteeing reliable fit in assemblies. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
