1/2-Inch Drive 21MM Deep Impact Socket, MS21 6-Point, Green Protective Sleeve

Brief Overview

This is a purpose-built deep impact socket designed for critical automotive applications where fastener protection and durability matter. The 85mm depth and green protective sleeve are specific design choices for wheel service on Hyundai i30, Tucson, and Kia platforms—vehicles where standard sockets can damage premium finishes or fastener coatings.

The 6-point design provides reliable grip without cam-out, while the impact-grade construction handles pneumatic tools reliably. If you're stocking solutions for European vehicle service, pair this with standard 6-point impact sockets in complementary sizes to create a complete wheel-service package for your customers.

Key Features

• 85mm Deep Length: Extended reach for wheel hub and axle fasteners
• 6-Point Internal Profile: Precise grip minimizes fastener rounding and cam-out
• Green Protective Sleeve: Rubberized coating protects wheel finishes and fastener coatings from impact tool contact
• Black Impact-Grade Steel Drive Section: 1/2-inch square drive, hardened for pneumatic impact tools
• Detent Hole: Secure retention on impact gun extensions
• Chamfered Working End: Smooth entry reduces fastener engagement resistance
• Dark Matte Interior Finish: Corrosion-resistant working surface

Why Distributors Stock This Socket

Specialized Application Focus: This socket addresses a specific market gap—wheel service on Hyundai and Kia vehicles where fastener and finish protection are customer expectations. It's not a general-purpose socket; it's a targeted solution that commands premium positioning.

Reduced Comebacks: The protective sleeve eliminates the most common customer complaint during wheel service—cosmetic damage to fasteners or wheel hub finishes. This reduces warranty claims and repeat work.

Professional Credibility: Offering specialized tooling for specific vehicle platforms positions your shop as vehicle-literate and detail-oriented, justifying higher labor rates.

Margin Opportunity: Deep impact sockets with protective sleeves are less common in standard assortments, allowing stronger gross margins than commodity hex sockets.
