The Proto PRO5316H Torqueplus™ Deep Socket features a 1/2 in drive and 1/2 in 6-point opening, designed to reach fasteners in recessed or hard-to-access locations with ease. The Torqueplus™ design drives on the flat of the fastener rather than the corner, reducing fastener rounding and improving torque transfer for professional-grade performance.
Built for industrial, MRO, and heavy-duty applications, this deep socket is ideal for mechanics, maintenance technicians, and tradespeople who demand reliable, long-lasting hand tools from a trusted professional brand.
