Snap-on is an American company that has been producing quality tools since 1920. Originally dismissed by mainstream tool distributors, the company began using independent salespeople, a tradition that continued. The company also relabelled Blue Point tools to supplement its line of available products. Given the popularity of Snap-on Tools, especially among mechanics, tools and tool boxes have become very collectable. The easiest way to track down the details of your Snap-on product is to use the Collecting Snap-on website, managed by Frank Murch.
Look on the back of your tool box and record the markings. This first stylised number or symbol is the year of manufacture. The next is a "K-series" number, including "K," "KT," "KR," or "KRA." This identifies the specific type and size of box. The final series of numbers is the product number.
Compare this to the date chart on the website Collecting Snap-on. Each model year after 1927 has its own special way of listing the year, using a stylised number or symbol.
Access the relevant catalogue on the website. Choose "Catalogs" then pick your year range from the drop-down menu and then the specific year.
Browse the catalogue to find your product. The model number should be listed starting with the "K." Most catalogues have a picture and description, including measurements.
Several online Snap-on forums provide information if you want to sell your toolbox.
Snap-on Tools often uses the same model number for products that were altered between manufacturing years. The date symbol is key.
