S-90269A572 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 Stainless Steel construction and protective Black Oxide finish.
• High mechanical strength and durability with a tensile strength of 70,000 psi and a shear strength of 35,000 psi for reliable performance under load.
• Precise location and smooth rotation for components with a smooth, accurately machined 40mm shoulder and a standard shoulder fit.
• Secure and tamper-resistant fastening enabled by the internal hex socket drive, requiring a 3mm hex key for installation.
• Accurate and reliable thread engagement ensured by the M5x0.8 coarse metric thread with a Class 5g6g fit tolerance.
• Consistent quality and material integrity guaranteed by a Rockwell B79 hardness rating.
• Compliance with international environmental regulations, being RoHS 3 and REACH compliant for global supply chain integration.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to solve critical alignment and pivot-point challenges in demanding industrial assemblies. The 316 Stainless Steel material provides exceptional resistance to corrosion from chemicals, saltwater, and other aggressive agents, making it ideal for food processing, marine, and chemical plant equipment. The precision-machined 40mm shoulder acts as a built-in spacer or pivot, eliminating the need for separate bushings and reducing assembly parts count. The Black Oxide finish not only enhances corrosion protection but also reduces galling and friction. Combined with the Class 5g6g thread fit and hex socket drive, this fastener delivers reliable, repeatable performance in machinery, automation systems, and precision instruments where dimensional accuracy and long-term durability are paramount.

Specification Summary & Compliance

This precision shoulder screw features an M5x0.8 coarse metric thread with a Class 5g6g tolerance for a secure fit. The shoulder diameter is 6 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 40 mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. The fastener is manufactured from 316 Stainless Steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
