Dating snap on sockets
Craftsman is a line of tools , lawn and garden equipment, and work wear. As with all Sears products, Craftsman tools were not manufactured by Sears during that company's ownership, but made under contract by various other companies. They were first sold in through the Sears catalog and in Sears retail stores. After the Sears-Kmart merger, the tools were also for sale in Kmart stores and through several other retailers. The Craftsman trademark was registered by Sears on May 20, Barrows' successor, Tom Dunlap, upgraded the quality of the tools and added chrome plating to them as America moved into the automobile age.

Snap-on History Timeline
Snap-On Wrench Date Codes. I have a set of Snap-On wrenches that I purchased new in That symbol on Doug's Dad's wrench is clearly I have some tubing wrenches that I am certain are original to the set with that symbol. Many of the wrenches and sockets I have do not exhibit the date symbols, but are from the original set. I think Doug's wrench could have been a replacement. I believe that wrench was replaced around due to the original being lost. I also have some other wrenches that were purchased as replacements for lost wrenches with the symbol. It was fun researching this and thanks for sharing.

Snap-On, Inc. To sell its products, Snap-On uses franchised truck drivers-nearly 4, of them-to purchase tools and equipment at wholesale prices and then market and deliver products directly to clients. Because Snap-On trucks are stocked with a wide variety of the firm's merchandise, customers are able to take delivery of many of their tools and equipment immediately upon purchase. Earnings growth proved less consistent. Many analysts became concerned about Snap-On's outlook in mid, when company officials revealed that third quarter earnings would be roughly 68 percent lower than in the third period of the previous year.
Snap-on Tools is one of the largest and best known makers of hand tools today. This article will look at the development of the company during the s, covering its first ten years of operations. The company's founding principle was the superiority of interchangeable socket tools over fixed or "tight" socket wrenches, and their first product was a modest collection of five drive handles and ten sockets.

1/2 Early Sockets
This application claims the benefit of U. Provisional Patent Application Ser. The present application relates generally to tools for driving fasteners, and in particular to sockets and drives for tools. A variety of wrenches and tools are commonly used to apply torque to a workpiece, such as a threaded fastener. The workpiece may be any number of different sizes and shapes and fitments. Accordingly, many tools include a driver adapted to mate with one or more different adapters, such as sockets, to engage and rotate the different workpieces.
Snap-on continued to improve its sockets throughout the s and beyond, although the pace of change wasn't as rapid as it had been in the s. In addition, numerous cosmetic changes were made to the socket styles, giving the sockets an updated appearance every few years. In addition to the improvements in socket construction, the number of applications for sockets expanded greatly, and Snap-on offered a much greater selection of sockets. Sockets were offered in shallow and deep styles, and with hex or double-hex and sometimes double-square broachings. The introduction of air-powered impact wrenches lead to a need for special impact-grade sockets, and the growing use of metric sizes required special sockets.
