Professional Applications & Engineering Value

This M4 thumb screw is engineered from 18-8 stainless steel to provide exceptional corrosion resistance and strength, solving common issues like fastener failure in humid or corrosive industrial settings. The knurled head offers a non-slip surface, enabling quick manual adjustments without tools, which is critical in maintenance panels, electronic enclosures, and machinery where frequent access is required. Its coarse metric thread (M4 x 0.7mm) and Class 6g thread fit ensure reliable engagement in metals and plastics, reducing cross-threading risks. The low-profile round head minimizes protrusion, making it ideal for compact designs in automotive, aerospace, and consumer electronics applications, while the partial threading allows for easier starts and secure holds.

Specification Summary & Compliance

This fastener features a metric M4 thread with 0.7mm pitch and Class 6g tolerance for precise fit, and is manufactured from 18-8 stainless steel with a tensile strength of 90,000 PSI. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in regulated industries worldwide.
