Professional Applications & Engineering Value
This M6 low truss head slotted screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress loads. The 18-8 stainless steel material, combined with a passivated finish, offers exceptional resistance to rust and chemicals, making it ideal for outdoor, marine, or chemical processing equipment. The low, wide truss head distributes clamping force over a larger area, reducing the risk of surface damage on softer materials like plastics or composites. With a coarse thread pitch and Class 6g thread fit, it ensures quick assembly and reliable performance in high-vibration environments such as machinery, automotive assemblies, and electrical enclosures. Fully threaded for maximum retention, this metric fastener provides consistent, secure connections in critical applications.
Specification Summary & Compliance
This screw features M6 x 1mm coarse pitch threading with a Class 6g tolerance for precise fit, and is fully threaded along its 20mm length. It meets standard metric threading specifications and is manufactured from 18-8 Stainless Steel with a passivated finish. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in environmentally conscious industries.
