Key Features & Benefits at a Glance
- Superior holding power with Class 5g6g thread fit ensuring reliable, vibration-resistant fastening in demanding applications.
- Exceptional durability provided by alloy steel construction and Rockwell C45 hardness, resisting wear and deformation under high stress.
- Precise installation and removal with a 1.5 mm hex drive, allowing for secure tool engagement in confined spaces.
- Optimized for coarse thread applications with a 0.5 mm pitch, enabling quicker assembly and strong grip in softer materials or where frequent adjustments are needed.
- Secure, non-slip fastening thanks to the cup tip design, which concentrates pressure and minimizes component surface damage.
- Guaranteed dimensional accuracy and interchangeability through compliance with DIN 916 and ISO 4029 standards.
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.
Professional Applications & Engineering Value
This M3 set screw is engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and precision equipment. Manufactured from high-strength alloy steel and heat-treated to a Rockwell C45 hardness, it resists loosening under vibration and heavy loads, a common failure point in dynamic environments. The headless design and hex drive allow for flush mounting and easy access in tight spaces, while the cup tip provides excellent bite into shafts and collars, preventing slippage. Its coarse metric thread with a 0.5 mm pitch ensures rapid installation and a robust hold, making it an ideal industrial set screw for permanent or semi-permanent positioning tasks.
Specification Summary & Compliance
This set screw features an M3 x 0.5 mm coarse thread with a Class 5g6g thread fit, ensuring precise dimensional tolerances for consistent performance. It is manufactured in accordance with the DIN 916 / ISO 4029 standard. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
