The Snap-on 144TMPB 1/4 Drive Socket Set includes a variety of sockets in both standard, SAE, and metric measurements. The set features a chrome surface finish and a 6 point drive type, making it durable and reliable for automotive use. If I’m understanding the history of the Snap-On brand’s logo correctly, this set was manufactured pre-1995, making it over 30 years old! This set, this old, in this exceptional condition is incredibly rare (IMHO, it belongs in a museum). As you can see in the 4th photo of this listing, there is a TREMENDOUS difference in the quality of craftsmanship and manufacturing standards between this set and the “same” set currently being produced by Snap-On (the photo shows the 10mm deep socket from this set on the left, and the “same” 10mm deep socket that was produced within the last 5 years). If you want a high-quality, Genuine Snap-On product, this is the set for you.
