How to Identify Snap-on Tool Boxes

by Tanya Gulliver

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 re-labeled 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 collectible. 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 stylized 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 stylized number or symbol.


Access the relevant catalog on the website. Choose "Catalogs" then pick your year range from the drop-down menu and then the specific year.


Browse the catalog to find your product. The model number should be listed starting with the "K." Most catalogs have a picture and description, including measurements.
