Professional Applications & Engineering Value

This M4 thumb screw delivers critical value in electronic enclosures, control panels, and industrial equipment where frequent access is required. The powder-coated aluminum head combines lightweight properties with excellent abrasion resistance, while the 400 series stainless steel body prevents galvanic corrosion and maintains thread integrity. The coarse metric thread (0.7mm pitch) ensures rapid installation and reliable engagement in sheet metal panels, eliminating cross-threading issues common in high-volume assembly environments. With its knurled texture and Phillips drive option, technicians can achieve secure fastening without specialized tools, reducing maintenance downtime in telecommunications, automotive, and machinery applications.

Specification Summary & Compliance

This captive panel screw features metric M4 x 0.7mm coarse threads with standard right-hand direction, manufactured to precise dimensional tolerances for consistent performance. The assembly combines a 13mm diameter knurled head with 7.2mm overall length, engineered for panels with 6.4mm hole diameter and 1.6-2.5mm thickness range. Compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restriction of hazardous substances for global industrial applications.
