Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical alignment and mechanical stress challenges in industrial assemblies. The 316 stainless steel material offers exceptional resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and outdoor equipment where moisture and chemicals are prevalent. The black oxide finish not only enhances aesthetic appeal but also adds a protective layer against abrasion and galling. The precisely machined 13mm shoulder length and controlled diameter tolerance ensure exact positioning in linkages, pivots, and rotating mechanisms, reducing wear on adjacent components. With a coarse thread and Class 5g6g fit, it provides robust holding power and vibration resistance in machinery, automotive, and automation systems, ensuring long-term reliability and reduced maintenance.

Specification Summary & Compliance

This shoulder screw features an M8x1.25mm metric coarse thread with a Class 5g6g thread fit for precise engagement. The shoulder diameter is 10mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 13mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. It complies with ISO 7379 for dimensional and mechanical requirements, and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental standards.
