Which TEKTON 1/2 Inch Drive Impact Socket Set Covers Your Jobs?

The TEKTON 1/2 Inch Drive Impact Socket Set, 21-Piece is the SAE option in this lineup. It contains 21 deep 6-point impact sockets from 5/16 to 1-1/2 inch, stepping in 1/32 and 1/16 inch increments at the small end, plus a carrying case. It is the only set here whose listing names the steel: 50BV30 chromium-vanadium or 4140 chromium-molybdenum depending on size, with a manganese phosphate coating against corrosion.

Every socket has both a laser-etched and a stamped size marking, radiused corners that push on the flats of the fastener instead of the corners, and a drive end that works with friction ring or detent pin anvils. The listing is inconsistent about depth: the title highlight and description say deep, while one feature line says the socket is a shallow length. The listed weight is 17.1 pounds, and the warranty is described as no time limits, no receipts.

This suits anyone working on older trucks, trailers, mowers or equipment with SAE hardware. If your vehicle is mostly metric, one of the metric sets below is the better starting point.

• 21 deep SAE sockets, 5/16 to 1-1/2 inch
• Cr-V or Cr-Mo steel with phosphate coating
• Laser and stamped size markings
• Carrying case included

The TEKTON 1/2 Inch Drive Impact Socket Set, 23-Piece is a shallow metric set with every size from 10 to 32 mm, no gaps, plus a storage case. Shallow sockets keep the overall length of the impact wrench and socket short, which helps when you are working in a crowded engine bay or wheel well.

It shares the dual size markings, full-length interior well, radiused corners and compatibility with both anvil types. The listing weight is 8.8 pounds, the lightest of the socket sets here. This listing does not state the warranty terms or steel alloy.

This is the everyday set for most modern vehicles, covering common caliper bracket, suspension and many lug nut sizes. It gives way to the 31-piece deep set when bolts sit on long studs, and to the 39-piece set when you need sizes under 10 mm or above 32 mm. If you already own a 3/8 drive impact socket set for smaller fasteners, this pairs neatly with it.

• 23 shallow sockets, 10 to 32 mm with no gaps
• Works with friction ring or detent pin anvils
• Laser and stamped size markings
• Storage case included

The TEKTON 1/2 Inch Drive Impact Socket Set, 31-Piece holds deep 6-point sockets from 8 to 38 mm, every millimeter included. Instead of a closed carrying case, the listing says it comes with socket rails and a tray, which suits a toolbox drawer or a wall-mounted setup.

Deep sockets reach nuts on long threaded studs, such as some lug nuts, U-bolts and suspension hardware, where a shallow socket would bottom out. The 36 to 38 mm range covers large axle and hub nuts. The same dual markings, radiused corners and dual-anvil compatibility apply, and the warranty is listed as no time limits, no receipts. At 24.2 pounds, it is the heaviest set here.

This is the pick for garage mechanics who want deep metric coverage in one purchase. If you prefer compact storage and shallow reach, the 23-piece set is smaller. If you want sizes past 38 mm, look at the 39-piece set.

• 31 deep sockets, 8 to 38 mm
• Socket rails and tray for storage
• Covers large axle nut sizes
• No time limit warranty per listing

The TEKTON 1/2 Inch Drive Impact Socket Set, 39-Piece has the widest metric range in this guide: every size from 8 to 44 mm, plus 46 and 50 mm. Those largest sizes are what you reach for on big hub nuts, farm equipment and heavy machinery.

The depth is unclear in the listing. The title highlight and item details call these shallow sockets, while one feature line and the description describe deep sockets. The listing also does not mention a storage case, unlike most sets here. The warranty is listed as no time limits, no receipts, and the listed weight is 23.9 pounds.

This suits people who want one set that covers nearly every metric fastener they will meet. If you do not work on anything larger than 32 mm, the 23-piece set is lighter and includes a case.

• 39 sockets, 8 to 44 mm plus 46 and 50 mm
• Friction ring or detent pin anvils
• Radiused corners resist round-off
• No storage case listed

The TEKTON 1/2 Inch Drive Hex Impact Bit Socket Set, 24-Piece is different from the rest: it drives hex (Allen) head fasteners instead of hex nuts and bolt heads. It includes 10 SAE hex bits from 1/4 to 3/4 inch and 14 metric hex bits from 6 to 19 mm, in a high-density polyethylene case that resists lubricants, fuels and solvents.

TEKTON uses a two-piece design here, so the bit and the socket body can use different steels and heat treatments. The listing says this makes the tool more durable than one-piece designs. The hex tips are machined to precise tolerances, and each piece carries laser and stamped size markings. The warranty is listed as no time limits, no receipts.

This suits anyone tackling caliper guide pins, drain plugs or axle bolts with hex sockets. It complements a regular socket set rather than replacing one. For our broader take on this range, see our TEKTON 1/2 impact socket set guide.

• 10 SAE and 14 metric hex bit sockets
• Two-piece bit and socket construction
• Solvent-resistant polyethylene case
• Laser and stamped size markings

The TEKTON 1/2 Inch Drive Impact Socket Set, 14-Piece contains only the large deep metric sizes, from 25 to 38 mm, with a storage case. It is designed to fill the top end of a collection rather than stand alone.

It keeps TEKTON’s dual size markings, radiused corners and dual-anvil compatibility. As with the 21-piece set, one feature line mentions a shallow overall length, while the title and highlight say deep. The listing weight is 18 pounds, and it does not state the warranty terms.

This suits someone who already owns the 23-piece shallow set and wants deep reach on axle and large suspension nuts. If you are starting from nothing, the 31-piece deep set covers these sizes and everything down to 8 mm.

• 14 deep sockets, 25 to 38 mm
• Storage case included
• Friction ring or detent pin anvils
• Radiused corners resist round-off
