Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address common challenges in precision assembly, such as component misalignment and pivot point wear. The 316 Stainless Steel material provides excellent resistance to chemicals and moisture, making it suitable for industrial applications in food processing, marine, and chemical equipment. The 20mm shoulder length with controlled tolerances acts as a precise dowel, maintaining alignment while allowing for rotational movement in machinery, linkages, and jigs. The knurled head and hex socket drive facilitate secure handling and high-torque installation, reducing the risk of tool slippage. By integrating a coarse pitch metric thread and ISO 7379 specifications, this screw ensures quick, reliable fastening in high-vibration environments, enhancing overall assembly durability and maintenance efficiency.

Specification Summary & Compliance

This shoulder screw features an M8x1.25 coarse pitch metric thread with a Class 5g6g thread fit for standard clearance. The shoulder diameter is 10mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 20mm with a tolerance of 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in accordance with ISO 7379 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
