Description

1/2-Inch Drive 46mm 12-Point Deep Impact Socket, 100mm Length

Brief Overview

This is a professional-grade deep impact socket engineered for high-torque pneumatic and impact applications. The 46mm 12-point design delivers precise engagement with fasteners while the extended 100mm length provides superior reach for recessed or hard-to-access applications. Constructed from impact-grade chrome molybdenum steel, it withstands repeated shock loads without fracturing or deforming. Pair this socket with compatible drive extensions or heavy-duty breaker bars for maximum leverage and control on critical fastening tasks.

Key Features

  • 46mm 12-Point Profile: Precise engagement minimizes cam-out risk and fastener rounding
  • Deep Socket Design (100mm Length): Extended reach for deeply recessed or countersunk fasteners
  • 1/2-Inch Square Drive: Industry-standard connection compatible with all 1/2" drive ratchets and impact tools
  • Chrome-Molybdenum Construction: Impact-resistant material absorbs shock loads without chipping or cracking
  • Matte Black Protective Finish: Corrosion resistance and improved grip in wet or oily conditions
  • Detent Groove Profile: Secure retention on drive heads prevents unintended socket ejection during operation

Business Advantages for Resellers

  • High-Margin Accessory: Deep impact sockets command premium pricing compared to standard depth alternatives
  • Essential for Specialized Work: Heavy truck, industrial equipment, and transmission rebuilds demand deep sockets—this size is frequently backordered
  • Durability = Repeat Orders: Chrome-moly construction ensures longevity; customers return for quality replacements when upgrading toolkits
  • Complements Your Existing Stock: Pairs naturally with 1/2" drive ratchets, breaker bars, and impact wrenches already in your inventory

  • Specialty mechanical work: Applications requiring precision engagement and extended reach

Why Choose This Socket

The 12-point profile prevents cam-out on hexagonal fasteners while providing finer engagement increments than 6-point alternatives. The extended 100mm length is critical for work where standard-depth sockets cannot physically reach the fastener head. Chrome-molybdenum steel absorbs repeated impact without fatigue failure—a critical advantage over cheaper carbon steel alternatives that can shatter under pneumatic tool stress.

Stock this socket for shops demanding professional-grade tooling. It's a reliable margin driver and an essential addition to any 1/2-inch drive impact system.
