Impact Socket 12-Point 27mm 1/2-Inch Drive, Chrome-Moly Construction

Brief Overview

This 27mm impact socket is engineered for professional-grade pneumatic impact wrenches and high-torque ratchets. Constructed from chrome-molybdenum steel with a dark phosphate finish, it delivers the durability required in heavy-duty automotive, industrial, and fleet maintenance environments. The 12-point drive geometry provides reliable fastener engagement while minimizing cam-out risk on seized or stubborn fasteners. Stock this size alongside smaller 12-point impact sockets and larger variants to offer your customers a complete fastener removal solution.

Key Features

• 12-Point Drive Design: Double-hex recess reduces fastener rounding and improves grip on hex bolts and nuts
• Chrome-Molybdenum Steel Construction: Superior impact resistance and durability compared to standard carbon steel
• Dark Phosphate Finish: Corrosion-resistant coating extends tool lifespan in wet or harsh shop environments
• 1/2-Inch Square Drive: Universal compatibility with standard impact wrenches, pneumatic ratchets, and hand tools
• Deep Socket Profile: 78mm overall length provides extended reach for recessed or tight fastening points
• Spring-Ball Retention: Molded slots at the base allow secure attachment to quick-change couplers or retaining rings

Business Advantages for Resellers

• High Turnover Potential: 27mm sockets are frequently requested in automotive transmission work, wheel service, and heavy equipment maintenance—stock depth directly increases sales velocity
• Margin-Friendly Category: Impact sockets command premium pricing versus standard sockets due to specialized material and manufacturing; excellent for bundling with impact wrenches
• Bulk Order Incentive: Professional shops typically purchase in sets (8–32mm range); offering this 27mm size as a standalone allows you to fill gaps in incomplete customer tool kits
• Durability Reputation: Chrome-moly construction reduces customer returns and warranty claims, strengthening your brand reliability

Why This Size Matters

The 27mm socket sits in the mid-to-upper range of standard automotive fastener sizes, making it essential for:

• Wheel hub and axle work where 27mm lug nuts and retaining bolts are common
• Transmission pan bolts and output shaft fasteners in heavy-duty applications
• Industrial equipment assembly and disassembly requiring mid-sized hex fastener access

Reseller Value Proposition

This is a core inventory item for any shop that services vehicles with metric fasteners. Unlike smaller impact sockets (12mm, 17mm) which experience higher churn, the 27mm size has reliable, consistent demand. Position it as part of a larger impact socket bundle to increase average order value and customer satisfaction.

Recommendation: Stock multiple units. Professional mechanics and fleet technicians often lose or damage sockets during high-torque work—repeat orders are virtually guaranteed.
