S-91273A794 M5 Shoulder Screws

Key Features & Benefits at a Glance

• High corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional mechanical strength with 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing performance
• Precision alignment and spacing ensured by the 10mm shoulder with controlled diameter tolerance for consistent assembly fit
• Secure, non-slip installation provided by the knurled socket head and 2.5mm hex drive, reducing tool slippage
• Enhanced durability and wear resistance from the black oxide finish, offering added protection against abrasion
• Accurate thread engagement with Class 5g6g fit and M5x0.8 coarse thread, minimizing cross-threading risks
• Broad regulatory compliance with RoHS 3 and REACH standards, ensuring safe use in various industries

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and rotational stability challenges in precision assemblies. The 10mm shoulder length acts as a precise locating dowel, maintaining component spacing in machinery, automotive, and electronic enclosures without additional bushings. Made from 18-8 stainless steel with a black oxide finish, it resists corrosion in humid or chemically exposed settings, while the Rockwell B55 hardness ensures the socket head and threads withstand repeated disassembly. The Class 5g6g thread fit and coarse M5x0.8 thread facilitate quick installation in high-vibration applications, reducing assembly time and improving production efficiency for industrial shoulder bolts used in pivots, gears, and linkages.

Specification Summary & Compliance

This metric shoulder bolt features a M5x0.8 coarse thread with Class 5g6g thread fit and a shoulder diameter tolerance of -0.04 to -0.01 mm for precise alignment. Manufacturing adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and material restrictions are met for global industrial use.
