Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
- Precise alignment and smooth rotation thanks to the 12mm shoulder diameter with tight tolerance of -0.072 to -0.01 mm
- High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing applications
- Secure, slip-resistant installation enabled by the 6mm hex socket drive and knurled head for enhanced grip during tightening
- Accurate and consistent threading with Class 5g6g thread fit and M8x1.25 coarse pitch for quick assembly and vibration resistance
- Durable, long-lasting operation backed by Rockwell B79 hardness and compliance with RoHS 3 and REACH environmental standards
- Versatile industrial compatibility with metric threading and standard socket head profile for broad application use
Professional Applications & Engineering Value
This M8 shoulder screw in 316 stainless steel is engineered to address critical industrial challenges, such as misalignment and corrosion-induced failure. The 10mm shoulder length with controlled tolerance ensures precise component spacing and reduces wear by acting as a pivot or bearing surface. Its hex socket drive and knurled head provide secure torque application, minimizing tool slippage in confined spaces. With a coarse thread pitch and Class 5g6g fit, it offers rapid assembly and maintains integrity under dynamic loads, making it ideal for machinery, automotive, and marine applications where corrosion resistance and reliability are paramount.
Specification Summary & Compliance
The screw adheres to metric threading standards with M8x1.25 coarse pitch and Class 5g6g thread fit for consistent engagement. Shoulder dimensions include a diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm, ensuring precise alignment. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally safe and regulated industrial use.
