Description

Cylinder Head Bolt Socket Tool – Torx E20, 1/2-Inch Drive

Brief Overview

This long-reach Torx E20 socket extension is engineered for precision cylinder head bolt work, where access and holding security are non-negotiable. The extended 140mm length lets technicians reach into tight engine bays without awkward positioning, while the anti-slip retention system keeps fasteners locked in place throughout the job. Built with a chrome-plated drive collar for durability and a black-coated shaft for visibility, this tool handles OEM cylinder head specifications reliably. For shops managing full engine reconditioning workflows, consider pairing this with smaller Torx socket variants to cover the complete fastener range.

Key Features

  • Torx E20 Female Recess – Precision-engineered star profile prevents fastener slipping and cam-out during high-torque cylinder head work
  • Extended 140mm Reach – Long design accesses recessed fasteners in confined engine compartments without extension bars
  • 1/2-Inch Drive Compatibility – Works seamlessly with standard pneumatic and manual ratchet systems already in your shop
  • Anti-Slip Retention Groove – Dual-purpose design: retention ring holds fasteners securely; groove allows optional O-ring with pin for secondary locking
  • Chrome-Plated Drive End – Durable corrosion-resistant collar with knurled grip pattern for positive hand control
  • Black Matte Shaft – High-visibility coated body contrasts with chrome ends; reduces tool mix-ups on busy shop floors

Why This Tool Matters for Your Business

Technician Efficiency: Eliminates fumbling with extension bars or adapters. One tool, one step closer to the bolt. Your labor hours on engine work drop measurably.
