S-94361A522 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional Strength & Durability: Made from high-strength alloy steel with a Rockwell C32 hardness and 140,000 psi tensile strength, ensuring reliable performance under high stress and load.
• Corrosion-Resistant Black Oxide Finish: Provides a protective layer that resists rust and oxidation, extending the screw's service life in demanding industrial environments.
• Precision Shoulder for Accurate Positioning: The 6mm diameter and 10mm length shoulder ensures precise component alignment and acts as a pivot or bearing surface, reducing wear on assembled parts.
• Secure & Efficient Hex Socket Drive: The 3mm hex drive allows for high-torque installation with standard tools, providing a secure, flush fit and preventing cam-out for reliable fastening.
• Coarse Thread for Quick Assembly: The M5x0.8mm coarse thread enables faster installation and is less prone to cross-threading, improving assembly efficiency in production lines.
• Industry-Standard Thread Fit: Class 5g6g thread tolerance ensures consistent, reliable engagement with mating components, providing a secure fit and vibration resistance.
• Compliant with Global Regulations: Meets RoHS 3 and REACH compliance standards, making it suitable for use in regulated industries and international markets.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot-point challenges in industrial machinery and precision assemblies. The alloy steel construction and black oxide finish provide the necessary durability and corrosion resistance for harsh operational environments, from automotive jigs to conveyor systems. The precision-machined shoulder (6mm diameter, 10mm length) acts as a dependable datum for rotating parts like gears and pulleys, eliminating misalignment and reducing eccentric loads that cause premature failure. Paired with the hex socket head and coarse metric thread, it ensures quick, high-clamp-force installation, making it ideal for applications requiring repeatable disassembly and reassembly without compromising thread integrity or positional accuracy.

Specification Summary & Compliance

This shoulder screw features an M5x0.8mm coarse metric thread with a Class 5g6g tolerance for precise fit. The shoulder diameter tolerance is -0.072 to -0.01 mm and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured to industry standards for socket head shoulder screws and is compliant with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006).
