Professional Applications & Engineering Value

These M4 thumb screws with knurled head design solve critical assembly challenges in industrial settings where frequent adjustments and tool-free access are essential. The 18-8 stainless steel construction provides exceptional corrosion resistance, making them ideal for electronics enclosures, machinery access panels, and laboratory equipment exposed to moisture or chemicals. The coarse metric threading (M4 x 0.7 mm) ensures rapid installation and removal cycles, while the raised round head profile with deep knurling offers positive grip even with gloved hands. Engineered for applications requiring repeated access, these fully threaded thumb screws maintain consistent performance in vibration-prone environments, reducing maintenance downtime and improving operational efficiency across manufacturing, automation, and electronic assembly sectors.

Specification Summary & Compliance

This metric thumb screw features precise M4 x 0.7 mm coarse threading with Class 6g thread fit tolerance for reliable engagement. Manufacturing complies with DIN 464 specifications ensuring dimensional accuracy and performance consistency. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances. The right-hand thread direction and fully threaded design provide maximum thread contact length of 16 mm, while the 16 mm head diameter with 3.5 mm height offers optimal torque application surface.
