CASOMAN 3/8" Drive Impact Socket Set — 49-Piece SAE & Metric, 6-Point Cr-V with Blow-Molded Case

CASOMAN 3/8" Drive Impact Socket Set is a 49-piece, heavy-duty Cr-V toolkit with 6-point deep and shallow sockets in SAE and metric sizes, built for impact tools and long-term workshop use.

This compact, complete set groups common fractional and metric sockets with impact-rated accessories inside a blow-molded carry case so you can tackle automotive, industrial, and DIY fastening jobs without hunting for the right size. Every component is made from drop-forged chrome vanadium steel and finished for corrosion resistance, while high-contrast size markings speed identification in low light.

What sizes are included and will they cover most repairs?

The set blends shallow and deep sockets across both SAE and metric ranges to handle nuts and bolts found on cars, lawn equipment, and machinery. Sizes span 5/16" to 3/4" (SAE) and 8 mm to 22 mm (metric), with duplicates in deep and shallow profiles for flexibility around studs and recessed fasteners.

• SAE shallow + deep: 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4"
• Metric shallow + deep: 8–19 mm, plus 21 and 22 mm
• Includes 3" and 6" extensions, universal joint, reducer, and 3/8"–1/4" adapter

How durable are these sockets for impact use?

Each socket is made from heat-treated chrome vanadium steel (50BV30) and finished with a black phosphate coating that resists corrosion and surface wear typical of impact use. The 6-point geometry reduces rounding on fasteners and keeps contact concentrated on flats rather than corners.

• Drop-forged and heat-treated Cr-V steel for high strength
• Black phosphate finish for rust resistance and longevity
• 6-point design minimizes slipping and fastener damage

What accessories come with the set and how do they improve workflow?

In addition to a broad socket selection, this kit supplies common impact accessories: two extension bars, a universal joint for awkward angles, and a reducer/adapter for cross-drive compatibility. These extras let you reach deep or recessed fasteners and switch between driver sizes without leaving the workspace.

• 3" and 6" impact-rated extensions for deeper reach
• 3/8" universal joint to access offset bolts
• 1/2" to 3/8" reducer and 3/8"–1/4" adapter for driver flexibility

How is the set organized and transported?

All pieces are arranged in a blow-molded plastic case sized for portability and tidy storage. The molded cavities prevent tools from shifting, making inventory quick and protecting sockets from knocks during transport.

• Heavy-duty blow-molded case with dedicated slots for each piece
• Compact footprint fits workshop shelves or a vehicle trunk
• High-contrast laser etching and hard-stamped size labels for fast identification

Who this is for: The CASOMAN 3/8" Drive 49-Piece Impact Socket Set is aimed at mechanics, maintenance technicians, and serious DIYers who need a reliable, impact-rated socket assortment in both SAE and metric sizes. If you use impact wrenches or routinely work on vehicles, engines, or heavy equipment, this set supplies the sizes and accessories to handle most common fastening tasks with durability and clear size markings for faster job turnaround.
