Overview
CASOMAN packs a master impact socket set with fifty pieces for quarter inch drive tools. A corrosion-resistant black phosphate finish covers the chrome vanadium steel, and the square drive end is standard.
Impact rated steel survives the hammering of an impact driver, which thin chrome sockets may not. The set size covers many fasteners. The listing never says which sizes, metric or inch, are included.
Who it's for
Auto hobbyists and industrial maintenance users with a quarter inch impact driver will get a wide range of small sockets. Anyone working on large nuts needs a bigger drive size.
Pros and cons
- Impact rated chrome vanadium steel
- Black phosphate finish resists corrosion
- Many pieces in one set
- Standard square drive end
- Socket sizes not itemized
- Measurement standard not stated
- Small drive size limits torque
- Case style not described
Performance notes
Impact sockets have thicker walls than hand sockets, so they absorb hammering without cracking. The black phosphate finish resists rust but wears at edges. A quarter inch drive limits the torque that can be applied.

Frequently asked questions
How should I care for the CASOMAN CS057 set?
Wipe the sockets dry after use and store them in their case. The black phosphate finish resists rust but can wear at the edges.
Can the CASOMAN CS057 sockets be used with a hand ratchet?
They have a square drive end and are impact rated, so they should fit a matching drive tool, but the listing recommends an impact driver.
