Professional Applications & Engineering Value
This M4 x 0.7mm x 8mm hex headless set screw delivers exceptional engineering value in precision assembly applications. The 18-8 stainless steel construction provides excellent corrosion resistance for harsh environments, while the Class 6g thread fit ensures consistent engagement and reliable clamping force. The vented design with 1.2mm diameter allows for pressure equalization in sealed systems or facilitates lubrication in moving components. The headless configuration with cup tip creates positive locking action on shafts and axles, preventing component slippage in machinery, automotive, and electronic assemblies. The 2mm hex drive offers secure tool engagement, reducing the risk of fastener damage during installation and maintenance cycles.
Specification Summary & Compliance
This metric set screw features M4 x 0.7mm coarse pitch threads with Class 6g tolerance per ISO standards, ensuring precise fit and reliable performance. The 8mm length provides optimal engagement depth for most industrial applications. Manufactured from 18-8 stainless steel with right-hand thread direction and cup tip configuration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in global manufacturing operations.
