Key Features & Benefits at a Glance
- Superior vibration resistance with 90° cone point that bites into mating surfaces for secure, permanent positioning
- Exceptional durability and wear resistance provided by alloy steel construction and Rockwell C45 hardness
- Reliable installation and removal with 2mm hex drive that prevents tool slippage and head stripping
- Optimal thread engagement with Class 5g6g thread fit ensuring consistent clamping force in coarse thread applications
- Wide industrial compatibility through compliance with both DIN 914 and ISO 4027 international standards
- Secure material contact from the cone point design that creates positive locking action on shafts and components
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications
Professional Applications & Engineering Value
This M4 set screw delivers critical holding power in demanding mechanical assemblies where vibration resistance and permanent positioning are essential. The alloy steel construction with Rockwell C45 hardness provides the necessary strength to withstand operational stresses without deformation. The 90° cone point design solves common loosening issues by creating a precise indentation in mating components, ensuring positive locking on shafts, collars, and pulleys. With coarse thread spacing and Class 5g6g thread fit, installation is efficient while maintaining consistent clamping force. The 2mm hex drive accommodates standard tools for reliable servicing in confined spaces typical of headless set screw applications across machinery, automotive, and precision equipment manufacturing.
Specification Summary & Compliance
This metric set screw features M4 x 0.7mm thread specifications with Class 5g6g thread fit tolerance per ISO standards. Manufacturing complies with DIN 914 ISO 4027 specifications for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
