Key Features & Benefits at a Glance
- Superior vibration resistance thanks to Rockwell C45 hardness and cup point design that bites into surfaces for secure, long-term fastening
- High-strength alloy steel construction ensures excellent durability and load-bearing capacity in demanding industrial environments
- Precise Class 5g6g thread fit guarantees smooth installation and reliable engagement with mating components
- Coarse 0.7mm pitch thread enables faster assembly and reduced risk of cross-threading compared to fine-pitch alternatives
- Compact 2mm hex drive allows for easy installation in confined spaces with standard tools
- Headless, right-hand thread design provides a flush finish and is ideal for applications where protruding fastener heads are not permissible
- Compliance with DIN 916 and ISO 4029 standards ensures consistent quality, dimensional accuracy, and international interoperability
Professional Applications & Engineering Value
This M4 set screw is engineered to solve critical challenges in precision assembly and machinery. The alloy steel core, hardened to Rockwell C45, resists wear and deformation under cyclic loads, making it ideal for vibration-resistant applications like motor mounts, gear assemblies, and tooling fixtures. The cup point creates a firm bite into shafts and hubs, preventing axial movement without damaging the component. Its headless design and metric coarse thread (0.7mm pitch) facilitate quick, secure fastening in tight spaces, reducing assembly time while maintaining Class 5g6g thread fit accuracy. These features make it a reliable choice for OEMs and maintenance teams in automotive, aerospace, and industrial equipment sectors.
Specification Summary & Compliance
This metric set screw adheres to DIN 916 and ISO 4029 specifications, ensuring dimensional precision with a Class 5g6g thread fit for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for use in regulated industries without hazardous substances.
