S-91273A801 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• Enhanced durability and wear resistance provided by the black oxide finish and Rockwell B55 hardness.
• Superior mechanical strength with 70,000 psi tensile and 35,000 psi shear strength for heavy-duty applications.
• Precise alignment and secure fit due to the standard shoulder with tight diameter tolerance of -0.04 to -0.01 mm.
• Easy installation and removal using a standard 3 mm hex key, facilitated by the knurled head for better grip.
• Reliable thread performance with Class 5g6g fit and M6x1 mm coarse pitch for quick assembly and vibration resistance.
• Compliance with environmental regulations, including RoHS 3 and REACH, ensuring safe and sustainable use.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for machinery, automotive, and electronics where exposure to moisture or chemicals is a concern. The black oxide finish not only enhances aesthetics but also reduces friction and galling during assembly. With a precision shoulder diameter of 6 mm and tight tolerances, it ensures accurate positioning of parts like gears and pulleys, minimizing downtime. The hex socket head and knurled texture allow for secure tool engagement, speeding up maintenance in high-volume production lines. Its right-hand metric thread with coarse pitch provides robust holding power in dynamic loads, supporting efficient and reliable operations.

Specification Summary & Compliance

This shoulder screw features an M6x1 mm metric thread with Class 5g6g fit for precise tolerance, ensuring consistent performance. The shoulder diameter is maintained at 6 mm with a tolerance of -0.04 to -0.01 mm, and the shoulder length is 4 mm with a tolerance of 0 to 0.25 mm, adhering to standard industrial specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious applications without hazardous substances.
