Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 140,000 psi tensile strength and 84,000 psi shear strength for reliable performance in demanding applications.
- Superior corrosion resistance due to the black oxide finish, extending service life in harsh industrial environments.
- Precision-engineered shoulder with tight diameter and length tolerances for accurate alignment and spacing in assemblies.
- High hardness rating of Rockwell C32 ensures excellent wear resistance and durability under repetitive use.
- Secure and efficient installation with a knurled socket head and 4 mm hex drive, preventing cam-out and enabling high torque application.
- Wide compatibility with Class 5g6g coarse threads (M6x1mm) for easy assembly and interchangeability in metric systems.
- Compliance with international standards including ISO 7379, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This M6 shoulder screw is engineered to address critical alignment and spacing challenges in precision machinery. The alloy steel construction, combined with a black oxide finish, provides robust resistance to wear and corrosion, making it ideal for automotive, aerospace, and heavy equipment applications. The precisely machined shoulder (8 mm diameter, 25 mm length) acts as a pivot or axle, ensuring components remain accurately positioned without additional bushings. Its coarse thread and right-hand thread direction facilitate quick assembly, while the hex drive and knurled head offer secure gripping during high-torque installation. By meeting ISO 7379 specifications, it guarantees dimensional consistency and reliability, reducing downtime and maintenance costs in industrial settings.
Specification Summary & Compliance
This shoulder screw adheres to precise dimensional standards, including a Class 5g6g thread fit for consistent engagement and a shoulder diameter tolerance of -0.072 to -0.01 mm. It conforms to ISO 7379 for metric shoulder fasteners and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
