Professional Applications & Engineering Value

This M5 set screw is engineered from zinc-plated alloy steel to address common industrial challenges like component slippage and corrosion in harsh environments. The 120° cone point ensures maximum grip by concentrating force on a small area, preventing loosening under vibration—ideal for securing pulleys, gears, and collars on shafts. With a Rockwell C45 hardness and coarse thread pitch, it resists wear and allows for rapid installation, reducing assembly time in production lines. The headless design and 2.5mm hex drive facilitate use in tight spaces, making it a reliable choice for precision machinery, automotive systems, and electronic enclosures where flush mounting is critical. Compliant with DIN 914/ISO 4027, it delivers consistent performance in metric applications, enhancing operational reliability.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 5g6g thread fit for accurate tolerance per ISO metrics, and a 0.8mm coarse pitch for efficient threading. It conforms to DIN 914 and ISO 4027 manufacturing specifications, ensuring reliability in industrial use. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility.
