Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M8 metric screws with Black-Oxide 18-8 Stainless Steel construction deliver exceptional corrosion resistance in challenging environments including manufacturing equipment, automotive assemblies, and outdoor structures. The hex drive design ensures secure torque transmission during installation, while the coarse thread pitch (1.25mm) provides superior performance in materials where fine threads might strip or fail. The rounded head style creates a low-profile finish that reduces the risk of snagging in moving machinery. With full threading along the 20mm length, these screws distribute clamping force evenly, making them ideal for applications requiring consistent pressure distribution and vibration resistance in mechanical assemblies and structural frameworks.
Specification Summary & Compliance
This M8 x 1.25mm x 20mm screw features Class 6g thread tolerance per metric standards, ensuring precise fit and reliable performance. Manufactured to meet ISO 7380 specifications for dimensional accuracy and mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted hazardous substances for safe industrial use worldwide.
