Description

1/2-Inch Drive Triple Square XZN10 Ball-End Bit Socket

Brief Overview

This is a specialized 1/2-inch drive triple square (XZN10) ball-end bit socket engineered for intake manifold disassembly on turbocharged TDI and TSI engines in 2013–2018 Volkswagen Golf and Audi A3 models. The ball-end design enables precise engagement in confined engine bays where straight-wall sockets cannot reach. If your shop handles modern VAG platform service work, you'll also benefit from stocking complementary standard hex bit sockets for broader fastener coverage across your operations.

Key Features

  • Triple Square (XZN10) Design: Multi-lobed profile prevents cam-out and strips on tight fasteners common in modern engine work
  • Ball-End Geometry: Permits angular access to fasteners in recessed or tight spaces without socket rotation limitations
  • 140mm Overall Length: Balanced reach for intake manifold bolts without excessive leverage or binding
  • Cr-V Construction: Chromium-vanadium alloy delivers durability and hardness essential for precision fastener work
  • 1/2-Inch Drive: Compatible with standard 1/2" drive ratchets, extensions, and breaker bars
  • Knurled Grip Band: Slip-resistant handling during high-torque assembly sequences

Business Advantages for Resellers

  • Niche Professional Application: VAG turbo engine service is a high-margin specialty—this socket addresses a specific, documented technical need
  • Repeat Customer Value: Shops specializing in TDI/TSI platforms require this tool for warranty work and full-service rebuilds
  • Inventory Efficiency: One specialized socket eliminates multiple failed attempts with generic tools, reducing labor callbacks
  • Margin Protection: Difficult-to-source specialty tools command premium pricing compared to standard socket sets

Why This Socket Matters

Modern turbocharged engines pack components tightly around the intake manifold. Access is severely limited, and traditional socket designs leave fasteners partially engaged. The ball-end triple square socket solves this by:

  1. Engaging XZN10 fasteners at compound angles (not just 90 degrees)
  2. Maintaining full contact pressure to prevent fastener damage
  3. Reducing reassembly time on high-labor diagnostic and repair procedures

This is a required tool for any shop advertising VAG turbo engine service. Without it, technicians default to hand tools or risky workarounds that extend labor time and increase defect risk.

Stock this socket as a core part of your specialty engine service lineup. It's a low-volume, high-confidence seller that builds shop reputation and protects labor margins on complex engine work.
