Key Features & Benefits at a Glance
- Superior holding power with a 120° cone point that bites into materials for secure, vibration-resistant fastening
- Exceptional durability from alloy steel construction and Rockwell C45 hardness, resisting wear and deformation under heavy loads
- Precise thread engagement with Class 5g6g fit and coarse 1.25mm pitch for quick installation and reliable performance in high-stress applications
- Easy installation and removal using a standard 4mm hex key, ideal for confined spaces due to the headless design
- Broad industrial compatibility meeting DIN 914 and ISO 4027 standards, ensuring interchangeability and quality assurance
- Environmental compliance with RoHS 3 and REACH regulations, making it safe for use in regulated industries and export markets
- Right-hand coarse threading provides strong holding in softer materials and faster assembly compared to fine threads
Professional Applications & Engineering Value
This M8 set screw is engineered to solve critical fastening challenges in industrial settings where slippage and loosening under vibration are major concerns. The alloy steel construction and Rockwell C45 hardness ensure it maintains clamping force in high-torque applications, while the 120° cone point creates a permanent indentation for maximum grip on shafts, collars, and gears. Its headless design and 4mm hex drive allow for flush mounting in space-constrained assemblies, making it ideal for machinery, automotive components, and precision equipment. The coarse metric thread with Class 5g6g tolerance ensures quick, accurate installation, reducing assembly time and improving production efficiency in industrial set screw applications.
Specification Summary & Compliance
This set screw features M8 x 1.25mm coarse metric thread with Class 5g6g fit for precise dimensional accuracy. It complies with DIN 914 and ISO 4027 manufacturing standards, ensuring consistent quality and performance. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for global industrial use.
