Description

3/4-Inch Drive Impact Socket, 55mm Hex, 6-Point Heavy-Duty

Brief Overview

Built for heavy industrial fastening applications, this 3/4-inch drive impact socket delivers robust performance on large fasteners. The 55mm six-point design provides secure engagement and reliable torque transfer on impact wrenches. The thick-walled construction and phosphate-grade finish withstand repeated impact cycles, making it an essential accessory for shops that work with large machinery, commercial vehicles, and industrial equipment. Pair this with smaller hex impact sockets to build a complete fastener coverage set for your operation.

Key Features

  • 3/4-inch Square Drive: Direct compatibility with 3/4-inch impact wrenches and air tools
  • 55mm Six-Point Hex: Secure engagement prevents rounding and cam-out on large fasteners
  • Impact-Grade Construction: Reinforced sidewalls and chamfered edges absorb shock loading without cracking
  • Phosphate Finish: Corrosion-resistant protective coating extends tool life in demanding conditions
  • Locking Pin Retention: Ball/pin groove and radial hole ensure socket stays firmly seated during operation
  • Precision Bore: Tight tolerances guarantee proper fit and torque transmission

Why This Socket Matters for Your Business

Operational Efficiency: Large fastener work represents a significant portion of commercial and industrial service revenue. This socket fills a critical gap for shops handling heavy-duty applications—trucks, construction equipment, industrial machinery—where standard socket sets fall short. Your technicians will reach for this tool regularly, reducing downtime and customer callbacks.

Durability & Margin Protection: Impact sockets fail when they crack, cam-out, or round internal profiles. The heavy-duty construction here minimizes warranty returns and complaint calls. A reliable 55mm socket justifies itself through reduced replacement costs and customer satisfaction.

Competitive Positioning: Shops that stock comprehensive impact socket ranges (from 22mm through 55mm) position themselves as full-service providers. Customers recognize this—and they're willing to stay loyal to a shop that has the right tool on the first visit.

Reseller Value Proposition

Stock this socket as part of a tiered impact socket range. Customers purchasing a 3/4-inch impact wrench expect sockets in 22mm, 27mm, 30mm, 32mm, 36mm, and 41mm at minimum—and your premium customers will ask for larger sizes like this 55mm. Bundle smaller sockets with the wrench at point of sale, and position larger sizes as high-margin add-ons for specialty work.

This is not an impulse purchase—it's a professional necessity. Position it accordingly in your catalog and pricing strategy.
