Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 18-8 Stainless Steel material provides excellent corrosion resistance, while the Black Oxide finish adds an extra layer of protection against wear and galling. The precision-machined shoulder (8mm length, 10mm diameter) acts as a pivot or bearing surface, eliminating misalignment in assemblies like machinery linkages, rotating parts, and precision instruments. The knurled socket head ensures a firm grip during installation, reducing tool slippage. With its coarse thread pitch and Class 5g6g thread fit, it offers reliable fastening in high-vibration environments, making it ideal for automotive, packaging equipment, and automated systems where precision shoulder bolts are essential for operational integrity.
Specification Summary & Compliance
This shoulder screw features an M8x1.25mm coarse metric thread with Class 5g6g tolerance for consistent fit. The shoulder diameter is controlled to -0.072/-0.01 mm tolerance, and shoulder length to 0/+0.25 mm, ensuring precise alignment. Manufactured to ISO 7379 specifications, it is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial components.
