- High-strength performance with 70,000 psi tensile strength and 45,000 psi shear strength for demanding applications.
- Easy installation and removal using a standard 6mm hex drive and knurled head for improved grip.
- Reliable thread engagement with Class 5g6g thread fit and coarse M8x1.25 pitch for quick assembly.
- Compliance with international standards including ISO 7379, RoHS 3, and REACH for quality assurance.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address common industrial challenges such as component misalignment and vibration-induced loosening. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for machinery, automotive, and electronics assembly where environmental factors are a concern. The black oxide finish not only adds an extra layer of protection but also reduces friction during installation. With a knurled socket head and hex drive, it ensures secure tool engagement, minimizing slippage in high-torque scenarios. The precise shoulder diameter and length allow for accurate pivoting and spacing in rotating parts, reducing wear and maintenance costs. Ideal for use in jigs, fixtures, and linkages, this screw delivers consistent performance under high shear and tensile loads, enhancing overall system reliability.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit with M8x1.25 coarse pitch, ensuring reliable fastening in metric applications. Dimensions include a shoulder diameter of 12 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 6 mm (tolerance: 0 to 0.25 mm) for precise engineering fits. It complies with ISO 7379 manufacturing standards and is verified to be RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety regulations for industrial use.
