A 3/8 inch drive socket set is the one most people reach for first, because it covers most car, bike, and household jobs. This comparison puts one 3/8 inch drive mechanics set each from DEWALT, CRAFTSMAN, GEARWRENCH, and TEKTON side by side on piece count, ratchet, warranty, and price.
How We Chose
We picked four well known tool brands that sell 3/8 inch drive mechanics sets on Amazon. The sets are not identical: piece counts run from 46 to 61, and a higher count can include extension bars and adapters rather than more sockets, so the cheaper sets are not necessarily missing sizes you need. Specs come from each brand’s own product page, and the DEWALT, CRAFTSMAN and GEARWRENCH pages also give the warranty for these models. The TEKTON product page names the set and gives its piece count and ratchet, but its warranty comes from TEKTON’s brand-wide warranty page, which does not name the set. Warranty terms come from the manufacturer’s own website where it names the model or product line, then from the Amazon listing, and we say so where neither gave a length. This is a researched comparison, not a hands-on test, so we make no claims about ratchet feel or long term durability beyond what each listing says. Prices are Amazon prices checked in September 2026 and can change.

Check Price on Amazon →Our Take
If you want a solid set for the least money, the DEWALT is the pick at $39.99 with 50 pieces. If you want the most pieces, the CRAFTSMAN gives you 61 for $69.98. The GEARWRENCH and TEKTON cost more. The GEARWRENCH has the smallest ratchet swing arc, 3 degrees, and the TEKTON has a quick-release ratchet and a no-time-limit warranty, though it also has the fewest pieces. We did not test any of them, so this is based on what the listings and manufacturer pages say.
Frequently Asked Questions
What does 3/8 inch drive mean?
It is the size of the square drive on the ratchet and inside the sockets. 3/8 inch is the common middle size for automotive and general repair work, and all four sets here are 3/8 inch drive.
Do I need both SAE and metric sockets?
SAE (inch) sizes fit most older American equipment and household fasteners, and metric sizes fit most modern cars and imports. The DEWALT and GEARWRENCH listings show both, the TEKTON lists inch and metric sockets, and the CRAFTSMAN listing did not state sizes in the fields we checked.
What is a 6-point socket?
A 6-point socket grips the flats of a bolt head and is less likely to round it off than a 12-point socket. The DEWALT, GEARWRENCH, and TEKTON listings say 6-point, and the CRAFTSMAN listing did not state it in the fields we checked.
Does ratchet tooth count matter?
More teeth means a smaller swing arc, which helps in tight spaces. The DEWALT and CRAFTSMAN list 72 teeth with a 5 degree arc, the TEKTON lists 90 teeth with a 4 degree arc, and the GEARWRENCH 120XP has two 60-tooth pawls for 120 positions and a 3 degree arc.
