Description

3/8-Inch Drive 12-Point Short Hand Socket, 20mm, 30mm Length

Brief Overview

This 20mm 12-point short hand socket is engineered for professionals who demand precision and reliability in confined working spaces. The compact 30mm length combined with the 3/8-inch square drive makes this socket ideal for automotive assembly, equipment maintenance, and tight-access fastening tasks. Part of a complete professional socket range from 8mm to 24mm, this individual socket delivers the durability and accuracy expected in high-rotation industrial environments. Pair with complementary socket sizes for a complete toolkit to maximize shop productivity.

Key Features

  • 12-Point Internal Profile: Twelve contact points engage fasteners with precision, reducing cam-out and fastener damage on tight or partially stripped bolt heads
  • 3/8-Inch Square Drive: Standard professional-grade connection compatible with all 3/8" ratchets, extensions, and drive tools
  • Compact 20mm Socket Size: Fits standard M20 hex fasteners—common in automotive and industrial assemblies
  • Short 30mm Body: Abbreviated length provides critical access to fasteners in confined engine bays, tight bolt clusters, and recessed mounting points
  • Knurled Grip Band: Textured center band improves finger control during hand-tightening and socket positioning
  • Chrome-Plated Finish: Corrosion-resistant coating extends tool life in humid and salt-exposure environments
  • Chamfered Opening Edge: Slightly beveled socket entry guides fasteners smoothly onto the 12-point profile, reducing installation time
