SK PROFESSIONAL TOOLS
SK PROFESSIONAL TOOLS, founded in 1921 in Chicago, Illinois, is a manufacturer of hand tools for industrial and professional use. The brand is known for its sockets, wrenches, and extensions, produced primarily from chrome vanadium steel with a chrome finish for corrosion resistance. Product families include SAE and metric hand sockets in 1/4", 3/8", and 1/2" drive sizes, available in 6-point and 12-point configurations, standard and deep lengths. The line also includes combination wrenches, flex and wobble socket extensions, and related accessories. Tools are designed to meet ANSI and ASME specifications for torque and durability, with typical hardness ratings of HRC 48-52 on drive ends. 3G Electric supplies over 1,000 SKUs from SK PROFESSIONAL TOOLS, covering socket sets, individual sockets, extensions, and wrenches. The inventory includes both SAE and metric sizes, with socket sizes ranging from 7/32" to 7/8" and 20 mm to 32 mm. All items are finished in chrome for surface hardness and rust protection. 3G Electric supports global procurement with logistics coordination, enabling plant engineers and maintenance managers to source replacement tools for assembly lines, repair bays, and field service operations. The catalog includes standard and deep sockets for fastener access in confined spaces, as well as flex extensions for angled applications. No special coatings or insulation are offered on standard products; tools are intended for manual use on fasteners within rated torque ranges. The brand's long production history and focus on industrial-grade tooling make it a reference for maintenance and repair tasks requiring repeatable fit and finish.
