S-90269A567 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 and 35,000 psi shear strength for reliable performance under high stress.
• Precise location and smooth rotation enabled by the 110mm long, finely toleranced shoulder with a smooth head texture.
• Secure and flush installation using the internal hex socket drive, providing a clean profile and high torque capability.
• Consistent and reliable thread engagement ensured by the Class 5g6g thread fit for metric coarse (M5 x 0.8mm) threads.
• Enhanced durability and minimal light reflection from the black oxide finish, which also adds a layer of corrosion protection.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and global market acceptance.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to provide a robust and precise pivot, axle, or spacer in demanding assemblies. The 316 stainless steel material offers excellent resistance to chemicals and corrosion, making it suitable for marine, chemical processing, and food-grade equipment. The long 110mm shoulder acts as a precision-machined dowel, ensuring accurate alignment of moving parts like gears, bearings, and linkages, which reduces wear and prevents binding. The black oxide finish on the socket head provides a low-glare surface and added corrosion resistance, while the hex drive allows for high tightening torque in confined spaces. This combination solves critical issues of part misalignment, corrosion-induced failure, and assembly inefficiency in industrial automation, machinery, and precision equipment.

Specification Summary & Compliance

This precision metric shoulder screw features an M5 x 0.8mm coarse thread with a Class 5g6g thread fit, ensuring standard compatibility and reliable engagement. The shoulder diameter is 6 mm with a tight tolerance of -0.072 to -0.01 mm, and the shoulder length is 110 mm with a tolerance of 0 to 0.25 mm, guaranteeing high dimensional accuracy for precise applications. The screw is manufactured from 316 Stainless Steel with a Rockwell B79 hardness and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, confirming its suitability for regulated and environmentally conscious industries.
