S-91273A405 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
• Precise alignment and reduced wear thanks to the 12mm shoulder with tight diameter tolerance (-0.04 to -0.01 mm).
• High-strength performance with a tensile strength of 70,000 psi and a shear strength of 35,000 psi for reliable load-bearing.
• Secure, non-slip fastening enabled by the knurled socket head and 3mm hex drive, even with gloved hands.
• Accurate and consistent mating ensured by the Class 5g6g metric thread with a 1mm coarse pitch.
• Excellent durability from a Rockwell B55 hardness, resisting deformation under stress.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant for safe use.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial applications. The 12mm shoulder length with its precise diameter tolerance acts as a reliable locating dowel, eliminating misalignment in assemblies and reducing wear on mating parts. Manufactured from 18-8 stainless steel, it offers excellent resistance to rust and corrosion, making it suitable for machinery, automation systems, and equipment exposed to moisture or chemicals. The combination of a knurled socket head and 3mm hex drive provides a secure grip for efficient installation and removal, even in confined spaces. Its Class 5g6g thread with a 1mm coarse pitch ensures quick assembly and a robust hold, delivering long-term reliability and reduced maintenance in demanding engineering environments.

Specification Summary & Compliance

This precision shoulder screw features an M6x1mm metric thread with a Class 5g6g tolerance for consistent fit. The shoulder diameter is held to a tight tolerance of -0.04 to -0.01 mm, and the shoulder length has a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial components.
