S-90269A717 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.
• Enhanced durability and strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance under high stress.
• Secure and non-slip installation thanks to the knurled head texture, providing excellent grip during manual or tool-assisted tightening.
• Precise alignment and spacing enabled by the integral shoulder with controlled diameter and length tolerances.
• Broad compatibility and easy assembly with a standard M8x1.25 coarse metric thread and Class 5g6g fit for consistent engagement.
• Convenient hex drive operation using a standard 5mm hex key for efficient installation and removal in confined spaces.
• Confident regulatory compliance meeting ISO 7379 specifications, RoHS 3, and REACH for use in regulated and international markets.

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 exceptional resistance to corrosion from chemicals, moisture, and salt spray, making it suitable for marine, chemical processing, and food machinery. The black oxide finish adds a layer of protection against galling and reduces light reflection. The precision-machined shoulder ensures accurate component positioning, eliminating the need for separate spacers or bushings, which reduces assembly time and potential failure points. Combined with the coarse thread pitch and Class 5g6g thread fit, it offers robust fastening in materials where fine threads might be prone to stripping, ensuring reliable performance in high-vibration environments like automation equipment and precision instruments.

Specification Summary & Compliance

This shoulder screw features an M8x1.25 mm coarse metric thread with a Class 5g6g thread fit, ensuring precise and reliable engagement. The shoulder diameter is 10 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 8 mm with a tolerance of 0 to 0.25 mm, providing high dimensional accuracy for alignment. It is manufactured in compliance with ISO 7379 specifications and is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety standards for global industrial use.
