Professional Applications & Engineering Value
This M8 shoulder screw with 1.25mm coarse thread pitch is engineered from alloy steel to address critical industrial challenges, such as misalignment and component wear in machinery assemblies. The black oxide finish provides a protective layer against rust and corrosion, making it ideal for automotive, aerospace, and manufacturing equipment where exposure to moisture and chemicals is common. Its shoulder diameter of 10 mm and precise thread length of 13 mm allow for accurate positioning and pivoting in linkages, bearings, and rotating parts, reducing downtime and maintenance costs. By combining high tensile strength and ISO 7379 standards, this fastener ensures long-term reliability in high-stress applications, enhancing overall assembly efficiency and safety.
Specification Summary & Compliance
This shoulder screw features a metric thread size M8x1.25mm with Class 5g6g thread fit for precise tolerance, ensuring consistent performance in coarse-thread applications. The shoulder diameter tolerance ranges from -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, adhering to strict manufacturing specifications. It complies with ISO 7379 for dimensional standards, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) for chemical safety, providing assurance for quality and regulatory requirements in industrial use.
