• Optimized thread engagement due to the 3.2 mm partially threaded design, preventing over-tightening and simplifying alignment.
• Consistent performance and interchangeability guaranteed by compliance with ASTM A581 manufacturing standards.
• Safe for sensitive applications as it is fully RoHS 3 and REACH compliant, free from hazardous substances.
• Versatile right-hand threading for standard installation, compatible with a wide range of metric assemblies.

Professional Applications & Engineering Value

This M3 thumb screw is engineered to address common challenges in industrial assembly, such as the need for frequent access and reliable fastening without tools. The 18-8 stainless steel construction offers excellent resistance to oxidation and corrosion, making it ideal for captive panel screws in electronics, machinery enclosures, and instrumentation. The knurled head provides a non-slip surface, enabling operators to tighten or loosen the screw quickly, even with gloves on. Its partially threaded design and coarse metric thread ensure secure holding in pre-tapped holes, reducing the risk of cross-threading and improving assembly efficiency in high-vibration environments. This combination of material durability and user-friendly design delivers long-term engineering value by minimizing maintenance downtime and enhancing operational safety.

Specification Summary & Compliance

This thumb screw features a metric M3 x 0.5 mm coarse thread with a right-hand direction and a thread length of 3.2 mm. The head diameter is 6.5 mm with a knurled texture for improved grip. Manufactured in accordance with ASTM A581 specifications, it ensures dimensional accuracy and mechanical consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various industrial and electronic applications without environmental or health concerns.
