kwb 372330 1/2 inch Drive 30 mm Hex Socket, Chrome Vanadium Steel

Professional mechanics and serious DIYers reaching for a 30 mm fastener on a 1/2-inch drive tool will find this socket gets the job done. The kwb 372330 is a standard-length, 6-point socket made from chrome vanadium steel with a polished chrome finish that resists corrosion and wipes clean after use. It fits any 1/2-inch square drive ratchet, breaker bar, extension, or torque wrench, and its DIN 3124 compliance means it meets the dimensional and strength expectations for manual socket use.

Key specifications

• Drive size: 1/2 inch
• Socket size: 30 mm
• Socket type: Hex (6-point)
• Material: Chrome vanadium steel (CrV)
• Finish: Polished chrome plated
• Overall length: 42 mm
• Standard: DIN 3124
• Application: Manual use

Why choose it

The 6-point design grips the flats of a hex fastener rather than the corners, reducing the chance of rounding off stubborn nuts and bolts. Chrome vanadium steel provides the strength needed for high-torque applications, and the polished chrome surface protects against rust in workshop or garage environments.

Ideal use cases

• Loosening and tightening 30 mm nuts and bolts
• Use with 1/2-inch drive ratchets, extensions, and torque wrenches
• Automotive, machinery, and general mechanical work

Good to know

This socket is intended for manual use only; do not use with impact wrenches unless the tool manufacturer permits it. The 42 mm overall length provides good access in most standard applications.
