Key Features & Benefits at a Glance
- Superior holding power with Class 6g thread fit ensuring precise, reliable engagement in demanding applications.
- Exceptional durability and wear resistance provided by the alloy steel construction and Rockwell B67 hardness rating.
- Secure and flush mounting thanks to the headless design and flat tip, preventing component interference.
- Simplified installation and adjustment using a standard flat-blade screwdriver with the slotted drive style.
- Optimized for coarse threading (0.45mm pitch) in Metric M2.5 size, enabling faster assembly and robust performance in softer materials.
- Guaranteed quality and interchangeability through compliance with DIN 551 and ISO 4766 international standards.
- Safe for use in regulated industries as it is fully RoHS 3 and REACH compliant, containing no hazardous substances.
Professional Applications & Engineering Value
This M2.5 x 0.45mm x 4mm alloy steel set screw is engineered to solve critical fastening challenges in precision assemblies. Its headless design and flat tip are ideal for applications where a protruding fastener head is not permissible, such as in compact machinery, optical devices, and precision instruments. The coarse pitch metric thread and Class 6g fit provide excellent resistance to vibrational loosening, making it a reliable choice for motors, gears, and pulleys. Manufactured from high-grade alloy steel and heat-treated to a Rockwell B67 hardness, it delivers the necessary strength and shear resistance for permanent or semi-permanent set applications, ensuring your components remain securely locked in position under dynamic loads.
Specification Summary & Compliance
This slotted headless set screw features a Metric M2.5 thread with a 0.45mm coarse pitch and a Class 6g tolerance for standard fit. It has a total length of 4mm with a flat tip. The manufacturing and quality are strictly controlled to meet DIN 551 and ISO 4766 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
