Professional Applications & Engineering Value

This zinc-plated cast iron thumb screw delivers exceptional value in applications requiring frequent manual adjustments, such as access panels, machinery guards, and electronic enclosures. The wing head design provides superior grip for hand-tightening operations, eliminating tool dependency while the coarse metric thread (M4 x 0.7 mm) ensures rapid engagement even in blind installations. The cast iron core with protective zinc plating offers optimal balance between mechanical strength and corrosion resistance, addressing common issues of fastener degradation in industrial environments. With full threading along its 40 mm length, this DIN 316 compliant component maintains consistent clamping force across varying material thicknesses, making it ideal for prototyping, maintenance, and production applications where tool-free accessibility is paramount.

Specification Summary & Compliance

This thumb screw features Class 6g thread tolerance per metric standards with M4 x 0.7 mm coarse pitch right-hand threading. Manufacturing complies with DIN 316 specifications for dimensional accuracy, including 8 mm head diameter (-2mm to 0 tolerance) and 40 mm fully threaded length. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, ensuring safe use across regulated industries.
