Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision equipment. The 316 Stainless Steel material provides exceptional resistance to corrosion from chemicals, moisture, and salt spray, extending service life in demanding environments. The 19mm shoulder length with precise tolerances ensures accurate positioning of moving parts like gears, pulleys, and bearings, reducing wear and preventing misalignment. The coarse metric thread (M8x1.25) and Class 5g6g thread fit facilitate quick, secure fastening even in high-vibration settings, while the knurled socket head with hex drive allows for high-torque installation without slippage. This combination makes it a reliable choice for applications requiring robust performance and dimensional stability.
Specification Summary & Compliance
This shoulder screw features an M8 x 1.25mm coarse metric thread with Class 5g6g tolerance for precise fit. The shoulder diameter is 10mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 19mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. 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.
