SK Hand Tools Tools and Equipment

A Century of American Craftsmanship

Few tool brands carry the weight of history that SK Hand Tools does. Founded in the early 1900s as the Sherman-Klove Company in Chicago, Illinois, SK's roots trace back to contract manufacturing and wartime munitions production during World War I. What began as a screw-machine products operation gradually evolved into one of the most respected names in professional hand tools — a journey spanning more than a century of American ingenuity and manufacturing pride.

The brand's identity as a dedicated tool maker took shape in the early 1930s, when the company inherited surplus socket wrench inventory from a defunct supplier and transformed it into the foundation of the S-K Tools line. From that pivot came a legacy of innovation that defined the professional tool market for generations. Among SK's most celebrated achievements is the patented fine-tooth round-head ratchet, developed by company engineer Theodore Rueb — a design so effective that it remains a benchmark in ratchet engineering to this day.

Built for the Professional Technician

SK's product philosophy has always centered on the working professional. Socket sets represent the heart of the SK lineup, with offerings spanning 1/4-inch through 3/4-inch drive in both SAE and metric configurations. SK's proprietary SuperKrome® finish — a high-polish chrome plating process — delivers exceptional corrosion resistance and a mirror-like appearance that holds up under the harshest shop conditions.

Beyond sockets, SK's wrench sets and combination wrenches are precision-forged for strength and durability, engineered to handle the kind of torque professional technicians apply day in and day out. For applications demanding exact fastener tension, the brand's torque wrenches bring the same standard of precision craftsmanship to critical tightening tasks. Completing the drive tool family, SK's ratchet wrenches allow mechanics to work efficiently in tight spaces, combining the access of an open-end wrench with the speed of a ratcheting mechanism.

Today, SK operates as part of GreatStar Industrial USA and boasts a catalog of over 3,000 products backed by a limited lifetime warranty. Whether you are a seasoned automotive technician or a serious DIY enthusiast, SK Hand Tools delivers the precision and durability that demanding work demands.
