Description

3/4-Inch Drive 6-Point Socket, 27mm

Overview

This 27mm 6-point socket is engineered for professional mechanics and industrial technicians who demand precision and durability in their socket collection. The 6-point geometry provides superior grip on hex fasteners, minimizing cam-out and fastener rounding—critical advantages when working with stubborn or damaged bolts. As a core size for automotive and industrial applications, the 27mm socket pairs seamlessly with larger-capacity sockets for heavy-duty work and smaller precision sockets for detailed assembly, making it an essential mid-range holding in any professional tool inventory.

Key Features

  • 6-Point Internal Profile: Reduces contact pressure on fastener corners, preventing rounding and extending bolt life.
  • Chrome-Finished Exterior: Bright, corrosion-resistant surface that resists rust and oxidation in demanding shop environments.
  • Stepped Cylindrical Design: Optimized wall thickness (22mm engagement) for strength without excessive bulk.
  • Detent Pin Hole: Integrated locking feature for secure attachment to ratchet handles and extensions, eliminating drop-offs during overhead work.
  • Chamfered Entry: Rounded socket mouth guides fasteners smoothly into engagement, reducing installation time and slippage.
  • Precision Machining: Tolerances held to specification ensure consistent fit across drive tools and multiple fastener types.
