Professional Applications & Engineering Value
This M6 left-hand thread metric screw is engineered to address critical challenges in machinery, automotive, and assembly lines where reverse-thread mechanisms prevent loosening from counter-clockwise motion. The 18-8 Stainless Steel material provides excellent resistance to rust and chemicals, reducing maintenance in humid or corrosive settings. Its rounded button head and 4mm hex drive allow for tight, low-clearance installations without protruding edges, minimizing snag risks. The fully threaded design and Class 6g thread fit ensure consistent clamping force, making it a reliable choice for high-vibration equipment, left-hand assembly jigs, and precision industrial fastening that demands durability and compliance.
Specification Summary & Compliance
This screw adheres to metric thread standards with M6x1mm coarse thread, Class 6g tolerance for precise fit, and a length of 20mm. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications requiring strict regulatory adherence.
