Description

Cylinder Head Bolt Socket Tool, Torx E12, 1/2-Inch Drive, 140mm Length

Brief Overview

This is a precision-engineered socket tool designed specifically for Torx E12 cylinder head bolts and similar hard-to-reach fasteners. The extended 140mm length combined with a dedicated anti-slip retention system makes it essential for engine assembly and maintenance operations where access is constrained and fastener security is non-negotiable. For shops requiring broader Torx coverage, larger Torx E-series socket tools or impact-rated Torx socket sets provide complementary options for different fastener sizes.

Key Features

  • Torx E12 Star-Shaped Socket: Precision-ground female Torx geometry prevents cam-out and fastener rounding
  • Extended Reach Design: 140mm overall length allows access to fasteners in confined engine compartments and recessed mounting points
  • Anti-Slip Retention System: Built-in spring-loaded retention pin and notched socket profile keep fasteners seated during installation and removal
  • 1/2-Inch Square Drive: Compatible with standard 1/2" drive ratchets, impact wrenches, and torque wrenches
  • Knurled Metal Collar: Textured grip zone for secure hand positioning and improved control during manual operation
  • Durable Metal Construction: Chrome-plated drive end and polished metal tip resist corrosion and wear in high-use environments
  • Optional O-Ring Retention Cap: Removable cap with pin-lock feature prevents tool loss in overhead or vertical work

Business Advantages for Resellers

  • Specialized Niche Market: Cylinder head work commands premium labor rates; shops need dedicated tools to justify those jobs
  • High Inventory Turnover: Engine rebuilders, performance shops, and fleet maintenance facilities replenish these tools regularly
  • Repeat Order Potential: Professional mechanics stock multiple sizes for different engine platforms and model years
  • Margin-Friendly Positioning: Specialized tools carry better margins than generic socket sets; position as essential inventory for engine shops
  • Cross-Sell Opportunity: Pair with larger E-series Torx sizes to build complete cylinder head kits and increase average order value

Why Mechanics Choose This Tool

Cylinder head fasteners require precise engagement and controlled removal to avoid thread damage. The anti-slip retention system keeps fasteners positively seated during insertion, reducing the risk of cross-threading or stripping. The extended length reaches recessed fastener pockets on modern engine heads where space is measured in millimeters. The knurled drive end and retention pin design eliminate fumbling in tight work spaces—critical when you're holding a camera, inspection tool, or light in your other hand.
