Professional Applications & Engineering Value

This M3 metric screw is engineered to address common industrial fastening challenges, such as material fatigue and loosening under dynamic loads. The zinc-plated steel construction provides a protective barrier against moisture and chemicals, extending service life in machinery, automotive assemblies, and electronic enclosures. With a rounded cheese head and slotted drive, it offers a low-profile solution for spaces with clearance constraints while allowing straightforward manual or automated installation. The partially threaded design and Class 6g thread fit ensure precise clamping force distribution, reducing the risk of strip-out and enhancing connection reliability in repetitive or high-vibration settings. Ideal for industrial applications requiring metric hardware that balances strength, compliance, and ease of use.

Specification Summary & Compliance

This screw adheres to DIN 920 specifications, with precise dimensions including a 4 mm head diameter, 16 mm length, and 9 mm minimum thread length. Threading follows Metric M3 x 0.5 mm coarse pitch with Class 6g tolerance for consistent fit. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence in global supply chains.
