S-92905A601 M3 x 3 mm DIN 915, ISO 4028 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Rockwell C45 hardness alloy steel construction, resisting deformation under high stress
• Precise and secure fastening ensured by the extended 1mm tip for deeper engagement and reduced loosening
• Reliable coarse thread (0.5mm pitch) provides faster installation and superior performance in softer materials
• Hex drive compatibility allows for high-torque application with standard tools, preventing cam-out
• Guaranteed dimensional accuracy with Class 6g thread fit for consistent, vibration-resistant assemblies
• Headless, space-saving design enables flush mounting in confined applications without protruding components
• Full regulatory compliance with RoHS 3 and REACH, ensuring safety and suitability for global markets

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision assemblies where space is limited and vibration resistance is paramount. The alloy steel construction, hardened to Rockwell C45, provides the necessary strength to prevent stripping and maintain clamp load in demanding applications such as securing gears, pulleys, and collars on shafts. The extended tip and coarse metric thread work in tandem to create a deeper, more reliable bite into the component, significantly reducing the risk of slippage or loosening under dynamic loads. Its headless design and compact 3mm length make it an ideal solution for machinery, automotive, and electronic equipment where a flush finish is required. Complying with DIN 915 / ISO 4028 standards, it delivers consistent quality and interchangeability for engineers and OEMs.

Specification Summary & Compliance

This metric set screw features an M3 x 0.5mm coarse right-hand thread with a Class 6g thread fit tolerance, ensuring precise engagement. The extended tip has a diameter of 2 mm with a tolerance of -0.25mm to 0 and a length of 1 mm with a tolerance of -0.25mm to 0. 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) regulations.
