  • Regulatory peace of mind with full compliance to RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

Engineered for precision industrial assemblies, these M6 flat head screws deliver exceptional performance in machinery, enclosures, and equipment where flush mounting is critical. The 18-8 stainless steel provides excellent resistance to rust and chemical exposure, extending service life in harsh conditions. The combination of a hex drive and fully threaded Class 6g body ensures high tensile strength and reliable fastening under dynamic loads. The vented design is particularly valuable in pressurized systems or applications requiring drainage, preventing failure due to trapped media. This metric screw is a trusted solution for OEMs and maintenance teams seeking durable, compliant, and easy-to-install machine screws.

Specification Summary & Compliance

This screw meets metric coarse thread specifications (M6 x 1mm) with a Class 6g tolerance for consistent fit. It is fully threaded and features a standard flat head with 90° countersink. Manufacturing and material standards adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and suitability for regulated industries.
