CASOMAN 3/8-Inch Drive Socket Sets, Small to Master

The CASOMAN 3 8″ Drive Impact Socket Set, model CS041, is the CASOMAN 49 piece socket set and our top all-rounder. It covers SAE 5/16 to 3/4 inch in deep and shallow 6-point sockets and metric 8 to 22 mm, all from drop-forged, heat-treated 50BV30 chrome vanadium steel with a black phosphate finish. Sockets have chamfered openings, laser-etched high-contrast markings and hard-stamped sizes.

The accessories make this set practical: 3-inch and 6-inch impact extensions, a 3/8-inch universal joint and a 1/2-inch to 3/8-inch reducer, all in a blow-molded case. The sockets also fit traditional ratchets. It weighs 4,160 g and carries a standard limited lifetime warranty per the listing. This is the set to buy if you work on older cars, bikes and home projects that mix fastener standards. If you only touch metric bolts, the 27-piece set is lighter. For longer reach, see our guide to 3/8 extension bars.

• SAE 5/16-3/4 in and metric 8-22 mm, deep and shallow
• 50BV30 Cr-V with black phosphate finish
• 3 in and 6 in extensions, U-joint and reducer
• Blow-molded carrying case

The CASOMAN 27 Pieces 3 8-Inch Drive Impact Socket Set includes 26 deep and shallow metric sockets from 7 to 19 mm, plus an impact drill socket adapter. It uses 50BV30 chrome vanadium steel with a black phosphate finish and a 6-point flank drive design that grips on the flats to prevent rounding.

The drill adapter lets you run sockets on an impact driver, handy for furniture builds, desk frames and quick jobs on metric bikes or cars. Sizes are laser etched and hard stamped, and the set comes in a blow-molded case with a limited lifetime warranty. The spec table lists a piece count of 1, which conflicts with the 27-piece title. There are no SAE sizes or extensions, so choose the 49-piece set if you need them.

• 13 deep and 13 shallow metric sockets, 7-19 mm
• Impact drill socket adapter
• 6-point flank drive

The CASOMAN 14PCS 3 8″ Drive 6 Pt. Mid-Length Socket Set covers metric 6 to 19 mm in a mid-length height, between shallow and deep. It is chrome vanadium steel with a mirror chrome finish, 6-point design, and laser-etched and roll-stamped markings. It weighs 880 g.

Mid-length sockets reach recessed bolts where shallow sockets fall short but deep sockets are too long for the space. Unlike most sets here, this listing does not describe the sockets as impact rated, and mirror chrome is typical of hand-tool sockets, so use them with a ratchet rather than an impact wrench. The listing does not mention a case. It suits a hand-tool drawer as a companion to a shallow or deep set.

The CASOMAN 13 Pieces 3 8-Inch Drive Impact Socket Set, model CS259, is the smallest set: 13 shallow metric sockets from 7 to 19 mm. It is drop-forged, heat-treated chrome vanadium with a black phosphate finish and a 6-point flank drive design, and it comes in a heavy-duty blow-molded case at 700 g.

This CASOMAN 13 piece metric set covers the sizes most common on modern cars, bikes and flat-pack furniture. Warranty wording conflicts: a feature bullet says standard limited lifetime, while the spec table says one year. Pick it as a starter set; add the 27-piece set if you need deep sockets.

• Shallow metric 7-19 mm
• Drop-forged Cr-V, black phosphate
• Blow-molded case

The CASOMAN 104 PCS 3 8″ Drive Master Impact Socket and Flex Socket Set, model CS542, is the most complete metric set. It includes 17 6-point and 17 12-point shallow sockets from 6 to 22 mm, 18 6-point deep sockets from 6 to 24 mm, 14 12-point deep sockets from 6 to 19 mm, 14 mid-length and 14 stubby sockets from 6 to 19 mm, and 10 flex sockets.

Four heights plus flex sockets mean you can reach almost any metric fastener, from a stubby in a tight engine bay to a flex socket at an angle. It is drop-forged Cr-V with a mirror finish and die-stamped markings, and weighs 7,860 g. It is metric only, so pair it with the 87-piece set if you need SAE. For more on angled access, see our guide to wobble sockets.

• 104 pieces, 6-point and 12-point
• Deep, mid-length, shallow and stubby heights
• 10 flex sockets

The CASOMAN 87PCS 3 8″ Drive Master Impact Socket Set, model CS105, is the SAE and metric master set. It uses impact-grade Cr-Mo steel, 6-point hex sockets, and includes standard and deep sockets, swivel sockets, star and inverted star sockets, an impact universal joint and extension bars, in a blow-molded case.

Swivel sockets let you run an impact wrench or impact driver on bolts at awkward angles, and star sockets handle the star-pattern fasteners found on many modern vehicles. The listing does not give full size ranges, so check the case layout before buying. Warranty wording again conflicts between limited lifetime and one year. This is the CASOMAN 87 piece master set for anyone who works on both SAE and metric vehicles with impact tools.
