How to identify snap-on tool boxes
Snap-on tool boxes are a collectable and useful item. (tool-set image by AGITA LEIMANE from

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.

Skill level:


  1. 1

    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.

  2. 2

    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.

  3. 3

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

  4. 4

    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.

Tips and warnings

  • 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.
