S-90269A713 M8 ISO 7379 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 minimum shear strength for reliable performance under high stress.
• Precision alignment and spacing ensured by the 50mm shoulder with tight length tolerance (±0.25mm), reducing component wear.
• Secure, non-slip installation provided by the knurled head and 5mm hex socket drive, allowing for high torque application.
• Consistent thread engagement with Class 5g6g fit and M8x1.25 coarse thread for quick assembly and vibration resistance.
• Enhanced durability and minimal light reflection from the black oxide finish, which also adds a layer of corrosion protection.
• Global compliance and reliability meeting ISO 7379 standards and being RoHS 3 & REACH compliant for use in regulated industries.

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical alignment and pivot point requirements in demanding industrial applications. The 316 stainless steel material provides excellent resistance to chemicals and saltwater, preventing failure in corrosive settings. The precision 50mm shoulder length with minimal tolerance acts as a reliable axle or spacer, maintaining exact part positioning in assemblies like machinery linkages, rotating fixtures, and conveyor systems. The black oxide finish not only enhances corrosion resistance but also reduces galling. Combined with the hex socket drive and knurled head, it ensures secure fastening in high-vibration environments, making it a vital component for automation, packaging equipment, and precision engineering projects where durability and dimensional accuracy are paramount.

Specification Summary & Compliance

This shoulder screw features an M8x1.25 metric coarse thread with a Class 5g6g thread fit for standard industrial use. The shoulder diameter is 10 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 50 mm with a 0 to 0.25 mm tolerance, ensuring high precision. It is manufactured to meet ISO 7379 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
