Key Features & Benefits at a Glance
- Superior holding power from alloy steel construction with Rockwell C45 hardness for reliable, vibration-resistant fastening in demanding applications
- Precise thread engagement with Class 5g6g fit and coarse M5x0.8mm threads ensures quick assembly and consistent clamping force
- Space-saving headless design allows for flush mounting in confined spaces where protruding fastener heads are not feasible
- Secure installation and removal facilitated by the 2.5mm hex drive, providing excellent torque transmission and reducing tool slippage
- Enhanced grip on shaft components due to the cup tip design, which bites into materials for superior anti-loosening performance
- Guaranteed dimensional consistency and interchangeability through compliance with DIN 916 and ISO 4029 international standards
- Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives
Professional Applications & Engineering Value
This M5 set screw delivers critical engineering value in applications requiring secure axial positioning of components on shafts and hubs. Manufactured from alloy steel and heat-treated to Rockwell C45 hardness, it resists wear and maintains clamping force under vibration and dynamic loads. The right-hand coarse thread (M5x0.8mm) with Class 5g6g tolerance ensures rapid installation and reliable performance in industrial machinery, automotive assemblies, and precision equipment. The hex drive and headless design are ideal for set screw applications where space is limited and a flush surface is required. The cup tip provides concentrated contact pressure, preventing slippage in high-torque environments and solving common loosening issues in rotating assemblies.
Specification Summary & Compliance
This metric set screw features M5x0.8mm coarse threads with a Class 5g6g thread fit, ensuring dimensional accuracy per DIN 916 and ISO 4029 standards. The screw has a length of 5mm, a 2.5mm hex drive, and a cup tip. It is manufactured from alloy steel and hardened to Rockwell C45. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
