A go-through screwdriver (also known as a strike-cap or demo screwdriver) is a heavy-duty hand tool engineered for driving stuck or stubborn fasteners and taking light impacts from a hammer. Constructed with a solid, continuous steel shaft that extends all the way through the handle to a steel striking cap at the end, it safely transfers impact force directly to the tip without damaging the handle. Key design features include a precision-machined, hardened black magnetic tip for optimal engagement with screw heads, a hex bolster near the base of the handle that allows a wrench to be applied for extra turning torque, and a high-visibility orange ergonomic handle with a lanyard hole for convenient tool storage. It is ideal for tough automotive, industrial, and mechanical applications.
