Key Features & Benefits at a Glance
- Superior holding power with a 90° cone point design that bites into materials for secure, vibration-resistant fastening
- Exceptional durability from alloy steel construction with Rockwell C45 hardness, resisting wear and deformation under load
- Reliable coarse threading (0.5mm pitch) for quick installation and reduced cross-threading risk in industrial applications
- Precise Class 5g6g thread fit ensuring consistent engagement and optimal clamping force in assemblies
- Compact hex drive (1.5mm) allows easy access and tightening in confined spaces with standard tools
- Headless, right-hand design provides flush mounting and standard directional installation for streamlined operations
- Full regulatory compliance with RoHS 3 and REACH, meeting international environmental and safety standards
Professional Applications & Engineering Value
This M3 set screw delivers critical performance in precision assemblies where space is limited and vibration resistance is paramount. Manufactured from alloy steel and heat-treated to Rockwell C45, it maintains structural integrity under repetitive stress, preventing loosening in machinery, motor mounts, and automation equipment. The 90° cone point concentrates pressure on a small surface area, creating a firm grip on shafts and collars without damaging components. With its coarse metric thread and Class 5g6g tolerance, it ensures rapid installation and consistent clamp load, reducing assembly time while meeting DIN 914 and ISO 4027 specifications for reliable industrial fastening.
Specification Summary & Compliance
This set screw features M3 x 0.5mm coarse metric threading with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The 8mm length and 1.5mm hex drive provide precise application control. It is manufactured in compliance with DIN 914 and ISO 4027 specifications, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements for environmental safety and restricted substances.
