S-92905A051 M3 x 4 mm DIN 915, ISO 4028 Set Screws

Key Features & Benefits at a Glance

• Superior torque transmission thanks to the hex drive design, preventing tool slippage during installation
• Enhanced component retention with the extended tip that bites securely into materials for reliable, vibration-resistant fastening
• Exceptional durability and wear resistance provided by the alloy steel construction and Rockwell C45 hardness
• Reliable thread engagement ensured by the Class 6g thread fit and coarse pitch for quick assembly in demanding applications
• Broad industrial compatibility with its metric M3 x 0.5mm specification and compliance with DIN 915/ISO 4028 standards
• Safe for regulated environments as it is fully RoHS 3 and REACH compliant, meeting strict environmental directives
• Precision fit and function from tight tolerances on the extended tip dimensions, ensuring consistent performance

Professional Applications & Engineering Value

This M3 alloy steel set screw is engineered to address critical challenges in precision assemblies where space is limited and reliability is non-negotiable. The headless design with a hex drive allows for flush mounting in tight spaces while enabling high torque application without stripping. Its extended tip provides a concentrated point of contact, increasing grip and resistance to loosening under vibration—common in machinery, automotive, and electronics. Manufactured from high-strength alloy steel and hardened to Rockwell C45, it withstands repeated stress and harsh operational conditions. The coarse metric thread (0.5mm pitch) and Class 6g thread fit ensure quick, secure fastening in metals and engineered plastics, making it ideal for set screw applications requiring precise axial positioning and alignment.

Specification Summary & Compliance

This set screw features an M3 thread size with a 0.5mm coarse pitch and a Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy and interchangeability. The extended tip has a length of 1 mm (tolerance: -0.25mm to 0) and diameter of 2 mm (tolerance: -0.25mm to 0) for precise application. It is manufactured in accordance with DIN 915 and ISO 4028 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safety and sustainability in industrial use.
