Description

3/4-Inch Drive Impact Extension Bar, 325mm Length

Brief Overview

This 325mm impact extension bar extends your reach on stubborn fasteners and hard-to-access work zones. Built for pneumatic impact wrenches and ratchets, it bridges the gap between socket and fastener without sacrificing torque delivery. The black-oxide impact-rated finish resists corrosion and absorbs shock loads common in high-speed pneumatic work. Pair this with shorter 100mm or 175mm variants for a flexible toolkit that covers most shop scenarios, or step up to impact-rated 1-inch drive extensions for heavy-duty industrial applications.

Key Features

  • 3/4-Inch Square Male Drive – Direct compatibility with standard 3/4" drive sockets and impacts
  • 3/4-Inch Square Female Socket – Accepts 3/4" drive tools (impacts, ratchets, breaker bars)
  • 325mm Overall Length – Reaches deep recesses and confined engine bays without excessive leverage stress
  • Pin-Retention Design – Both ends feature retaining pin holes (top and bottom) to prevent accidental socket separation during rapid pneumatic work
  • Impact-Rated Black-Oxide Finish – Absorbs shock loads from pneumatic tools; resists rust and corrosion on shop floors
  • Tubular Construction – Lightweight yet rigid; reduces user fatigue on extended reaches
  • Straight Shaft Design – No flex joints; ensures true torque transmission without deflection

Why Resellers Choose This

Reliable Margin on High-Volume Stock: Impact extensions are consumables in active shops—mechanics buy them regularly as wear items. Stock depth in multiple lengths ensures repeat orders.

Mechanic Retention Tool: Every shop needs extensions. Stocking the full 3/4" drive range (100mm, 175mm, 250mm, 325mm) positions you as a one-stop source and reduces customer trips to competitors.

No Brand Confusion: White-label design eliminates conflicts with exclusive distributor agreements—you resell under your own identity.

Recommended Application Context

  • Engine bay work – Spark plugs, alternator bolts, manifold fasteners on tight spacing

  • Industrial equipment – Machinery assembly, agricultural repair, mining tool servicing
  • Fleet maintenance – High-volume shops where time-saving reach prevents stripped fasteners

Your Competitive Edge

Stock this 325mm bar alongside the shorter 250mm impact extension to capture mechanics who need both precision and reach. The pin-retention feature reduces comebacks from lost sockets—a critical credibility factor in professional shops. At this length, it's the workhorse for tasks too deep for standard extensions but not demanding a full 1-inch drive upgrade.

Bulk Order Incentive: Volume purchases in mixed lengths (100mm–325mm sets) increase shop loyalty and reduce your inventory rotation time.
