Key Features & Benefits at a Glance
- Superior holding power with a cup point design that bites into materials for a secure, non-slip connection.
- Exceptional strength and durability provided by alloy steel construction and a Rockwell C45 hardness rating.
- Reliable and precise fit ensured by the Class 5g6g thread tolerance for consistent performance in demanding applications.
- Easy and secure installation with a hex drive style, allowing for high torque application in confined, headless designs.
- Broad industrial compatibility with a standard M2x0.4 mm coarse thread, making it a versatile metric fastener.
- Long-term operational safety with compliance to RoHS 3 and REACH environmental regulations.
- Guaranteed dimensional consistency by conforming to the internationally recognized DIN 916 and ISO 4029 standards.
Professional Applications & Engineering Value
This M2 set screw is engineered to solve critical challenges in precision assembly. The alloy steel material, heat-treated to a Rockwell C45 hardness, provides the necessary strength to resist shear forces and vibrational loosening. The cup point is specifically designed to concentrate pressure and create a permanent indentation in the shaft, preventing axial movement and ensuring the assembled components remain securely aligned. This makes it an indispensable industrial fastener for applications in precision machinery, automotive subsystems, and electronic enclosures where space is limited and a headless screw design is required. Its right-hand coarse thread and hex drive facilitate quick and robust installation, delivering reliable fastening solutions that maintain integrity over the product's lifecycle.
Specification Summary & Compliance
This set screw features an M2 x 0.4 mm coarse metric thread with a Class 5g6g thread fit, ensuring high dimensional accuracy and interchangeability. It is manufactured in compliance with the DIN 916 / ISO 4029 specifications, guaranteeing consistent quality and performance. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety standards for industrial components.
