S-90269A585 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life.
• Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi shear strength for reliable, high-stress applications.
• Precise alignment and location enabled by the smooth, standard shoulder with controlled diameter and length tolerances.
• Secure and efficient installation with a hex socket drive, preventing cam-out and allowing for high torque application in confined spaces.
• Enhanced durability and minimal reflectivity from the black oxide finish, providing added wear resistance and a professional appearance.
• Guaranteed dimensional accuracy with Class 5g6g thread fit and metric coarse threading (M5x0.8) for consistent performance.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant for use in regulated markets.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot point challenges in precision assemblies. The 316 stainless steel material provides excellent resistance to chemicals and saltwater corrosion, making it suitable for marine, chemical processing, and food industry equipment. The black oxide finish not only adds a layer of protection against abrasion but also reduces light reflection in sensitive optical or instrumentation setups. The defined shoulder length of 7mm acts as a precise spacer or pivot, eliminating the need for additional bushings and simplifying assembly in linkages, rotating shafts, and guide mechanisms. The hex socket drive ensures a secure fit during installation, preventing damage to the screw head and allowing for reliable maintenance in hard-to-reach areas, thereby reducing machine downtime and improving overall operational efficiency.

Specification Summary & Compliance

This metric shoulder screw conforms to standard M5x0.8 coarse thread specifications with a Class 5g6g thread fit for assured interchangeability. The shoulder diameter is manufactured to a tolerance of -0.072 to -0.01 mm, and the shoulder length to 0 to 0.25 mm, ensuring precise component location. The screw is produced from 316 stainless steel with a Rockwell B79 hardness and meets the requirements of RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its compliance for use in environmentally conscious and restricted substance-controlled applications.
