Description

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

Brief Overview

This is a purpose-built impact socket engineered for pneumatic impact wrenches and high-torque applications. The 12-point design distributes load across more contact points than traditional 6-point geometry, reducing fastener rounding and extending tool life. Constructed from chrome-molybdenum steel with a dark impact-grade finish, it's rated for the demanding conditions of automotive service, heavy equipment maintenance, and industrial assembly. Pair this with larger metric impact sockets or smaller metric counterparts to build a complete metric socket set for your shop.

Key Features

  • 12-Point Cavity: Distributes impact force across 12 contact points, minimizing fastener damage and cam-out on worn or damaged fasteners
  • 1/2-Inch Square Drive: Compatible with standard 1/2" pneumatic impact wrenches and ratchets
  • Chrome-Molybdenum Construction: Premium alloy steel formulation provides superior toughness and impact resistance compared to standard chrome-vanadium
  • Black Impact Finish: Durable matte coating protects against corrosion and identifies the tool as impact-rated
  • Retaining Pin Hole: Cross-drilled design accommodates standard retaining pins or ball detents for secure attachment to drive tools
  • Compact Length: 38mm overall length ensures access in confined spaces without excessive overhang

Business Advantages

For Resellers & Shop Owners:

  • High Demand Item: Impact sockets are consumable-equivalent tools with regular replacement cycles in busy shops
  • Essential for Pneumatic Shops: Non-negotiable for any facility using impact wrenches
  • Bulk Order Opportunity: Customers typically purchase full metric sets (8–24mm); this 12mm size is one of the most frequently replaced
  • Margin-Friendly: Standard industrial tool with predictable pricing and competitive wholesale margins
  • Cross-Sell Potential: Buyers of one impact socket frequently purchase complementary sizes and drive configurations

Professional Application Context

This 12mm socket is sized for mid-range fasteners commonly found in:

  • Automotive: Wheel lug nuts (with impact-rated drive tools), suspension work, engine bay assembly
  • Heavy Equipment: Excavator pins, loader linkage, truck suspension fasteners
  • Industrial Assembly: Machinery mounting bolts, structural connections requiring high-torque tightening

The 12-point geometry is particularly valuable when working with damaged or older fasteners where 6-point sockets would slip or strip the head.

Value Proposition

Stock this size as a high-rotation item. Professional shops replace impact sockets regularly due to battering from high-cycle pneumatic impacts. The 12mm is a top-three consumed size in most metric impact socket sets, making it an ideal candidate for bulk distributor orders and wholesale accounts.
