Professional Applications & Engineering Value

This M4 thumb screw delivers exceptional value in electronic enclosures, control panels, and industrial equipment where frequent access is required. The combination of powder-coated aluminum head and 400 series stainless steel construction addresses common challenges of corrosion resistance and mechanical durability. The knurled texture provides positive grip even with gloved hands, while the coarse metric thread (M4 x 0.7mm) ensures rapid installation without cross-threading risks. Engineered specifically for panel mounting applications with 6.4mm hole diameter compatibility, this captive panel screw maintains secure fastening across thousands of maintenance cycles, reducing downtime and replacement costs in demanding industrial environments.

Specification Summary & Compliance

This metric thumb screw features precision M4 x 0.7mm coarse threads with standard right-hand thread direction and ISO-compliant dimensions. The 13mm head diameter with 11.3mm height provides optimal torque application, while the Phillips No. 2 drive offers alternative installation methods. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial applications. The screw is specifically engineered for outer panels with 0.5mm to 1mm thickness and 6.4mm hole diameter requirements.
