1/4" Drive Ball-End Hex Bit, 4mm – VAG Engine Speed Sensor Tool
Brief Overview
This is a specialized 1/4" drive ball-end hex bit engineered specifically for removing and installing the G28 engine speed sensor on VAG 4-cylinder direct injection engines with turbocharging. The ball-end design enables angled access to tight sensor locations where straight-drive tools cannot reach. The 4mm hex size and 79mm overall length make this a precision fit for this critical diagnostic and maintenance task. When stocking VAG-focused service inventory, pair this with additional hex bit sockets to ensure comprehensive coverage across engine bay applications.
Key Features
- Ball-End Design: Enables fastener access at angles up to 25°, essential for confined engine bay work
- 4mm Hex Size: Matches VAG G28 sensor fastener specification exactly
- CR-V Socket (1/4" Drive): Industry-standard chrome vanadium for durability and compatibility with all 1/4" ratchets and impact tools
- S2 Bit Material: High-carbon steel hex shank resists deformation under pressure, critical for precision sensor work
- 79mm Overall Length: Optimized depth for accessing sensors mounted in tight locations without requiring extension bars
- Matte-Gray Finish with Knurled Grip Band: Improves tactile control during delicate sensor installation
Business Advantages for Resellers
- Niche Market Positioning: VAG-specific tools command premium margins with specialized automotive shops targeting European vehicle service
- Essential Diagnostic Tool: Engine speed sensor work is common maintenance on 1.4L turbo direct injection engines—recurring demand from shops servicing this popular platform
- Bulk Order Opportunity: Shops performing VAG engine diagnostics typically order multiple precision bits; recommend 6–12 unit quantities for consistent stocking
- Inventory Rotation: Complements existing 1/4" drive bit collections; fills a gap that generic hex bits cannot address
