A go-through screwdriver (also known as a strike-cap or demo screwdriver) is a heavy-duty hand tool engineered for driving stuck, rusted, or stubborn fasteners and enduring direct hammer impacts. Built with a continuous steel shank that passes completely through the handle to a solid metal striking cap at the top, it transfers striking force directly to the fastener tip without shattering the handle. Key design features include a precision-machined Phillips tip for a firm grip in cross-recessed screw heads, an integrated hex bolster at the shaft base that allows a wrench to be applied for extra leverage, and an ergonomic high-visibility orange handle complete with a hanging hole for convenient storage. It is an essential tool for demanding automotive, industrial, and heavy machinery repairs.
