• Superior thread fit with Class 6g tolerance guarantees consistent, high-quality engagement and reduces the risk of cross-threading.
• Easy installation and removal with a standard hex drive, providing a secure grip for efficient assembly and maintenance.
• Long-term durability and corrosion resistance from the high-strength alloy steel material, extending the service life of your assemblies.
• Guaranteed compliance and interchangeability by meeting DIN 915 and ISO 4028 standards, ensuring part reliability and global sourcing flexibility.

Professional Applications & Engineering Value

This M20x2.5mm metric set screw is engineered to solve critical challenges in industrial applications where components are subject to intense vibration and rotational forces. The alloy steel construction, hardened to Rockwell C45, provides the necessary strength to prevent loosening and maintain clamp load in heavy-duty machinery, automotive systems, and precision equipment. The extended tip and coarse thread design ensure deep, positive engagement with the mating part, effectively eliminating play and misalignment. As a headless screw with a hex drive, it offers a flush finish and easy access in confined spaces, making it an ideal precision set screw for permanent or semi-permanent fastening solutions that demand reliability and ease of service.

Specification Summary & Compliance

This set screw features a Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy and interchangeability. The extended tip has a length of 10.36 mm with a tolerance of -0.36mm to 0 and a diameter of 15 mm with a tolerance of -0.43mm to 0. It is manufactured in compliance with DIN 915 and ISO 4028 specifications and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
