Mustad Panelvit TSP Screw 4x20mm Black Reinforced Flat Head Deep Bit Socket

Product Overview

The Mustad Panelvit TSP 4x20 mm screw is a universal fastener for direct installation without pre-drilling, commonly used in woodwork, panel assembly, and mounting thin boards. Its black finish suits interior construction, furniture manufacturing, and paneling tasks, making it suitable for both residential and commercial applications where appearance and holding strength matter.
