Description

3/4-Inch Drive Impact Socket, 38mm Hex, 6-Point Heavy-Duty

Overview

This is a purpose-built impact socket engineered for high-torque pneumatic and cordless impact applications. The 38mm 6-point hex profile grips fasteners securely without cam-out, while the robust 3/4-inch square drive connects to impact wrenches, ratchets, and power tools without slippage. Part of a comprehensive range that includes smaller hex sockets for fine work and larger hex sockets for heavy-duty applications, this socket delivers consistent performance across demanding job sites.

Key Features

  • 6-Point Hex Profile: Prevents rounding of fastener corners, essential for reusable bolt applications
  • Heat-Treated Alloy Steel Construction: Absorbs impact energy without chipping or cracking
  • 3/4-Inch Square Drive: Standard connection for mid-range impact tools; reduces connection wobble
  • Retaining Ring Groove & Detent Hole: Allows secure attachment of locking pins or detent balls for tool retention
  • Matte Black Anti-Corrosion Finish: Resists rust and oxidation in humid environments
  • Thick-Walled Design: Distributes impact force evenly, extending socket lifespan

Business Advantages for Resellers

  • High Turnover Item: 38mm fasteners are common in automotive assembly, industrial machinery, and heavy equipment—expect consistent demand
  • Professional Shop Essential: Mechanics cannot function without a complete socket range; this size fills a critical gap
  • Durability = Repeat Sales: Impact-rated construction means fewer replacements, but shops will buy multiple sockets as their fleet grows
  • Competitive Bulk Pricing: Stock multiple sizes (22mm through 55mm) to position yourself as a one-stop supplier for pneumatic tool shops

Application Context

This socket is ideally suited for:

  • Automotive: Removing/installing 38mm wheel hub nuts, suspension components, and transmission hardware
  • Industrial Equipment: Heavy machinery assembly and maintenance where 38mm bolts are standard
  • Fleet Maintenance: Tire shops and service centers managing high-volume brake and suspension work

The 3/4-inch drive size positions this socket in the mid-torque range—powerful enough for most automotive work, yet manageable for hand control and precision placement. Not designed for ultra-heavy impact (1500+ ft-lbs); pair it with impact wrenches rated 200–800 ft-lbs for optimal performance.

Why Stock This Size

The 38mm socket addresses a genuine gap in many tool collections. While 36mm and 41mm sockets are more common, the 38mm is frequently required in European-specification machinery and vehicles. Shops that service diverse equipment will ask for it; having it in stock positions you as a thorough supplier.
