Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Conquer large fasteners with the DeWalt 7/8 in. SAE 6-Point Deep Impact Socket, engineered for 1/2 in. drive impact wrenches. Built to withstand demanding jobsite torque, this socket blends trusted DeWalt durability with a design that reaches where others can’t.

Why this socket stands out

  • 7/8 in SAE size delivers a precise, six-point engagement for secure grip on large hex fasteners, reducing cam-out and rounding under high torque.
  • 6-point profile maximizes contact with the nut flats for more torque transfer and longevity on stubborn hardware.
  • Deep impact design extends beyond standard sockets, letting you reach recessed nuts and bolts in tight spaces.
  • 1/2 in. drive compatibility pairs with common impact wrenches for versatile automotive and heavy equipment work.
  • Black oxide finish provides corrosion resistance and smooth operation across jobsite conditions.
  • Impact rated specifically designed to handle the hammering and torque of impact tools without cracking or flaking.
  • tuned for reliable seating: Nut End Outside Diameter 1-1/32 in, Drive End Outside Diameter 31/32 in, Nut Depth 23/32 in, Bolt Clearance Depth 1-25/32 in.
  • Retail-ready packaging in carded form for easy visibility and selection in professional tool racks.

Ideal for who needs it

This socket is perfect for automotive techs, fleet maintenance crews, shop technicians, and DIY enthusiasts tackling large hex fasteners with impact tools. If you regularly work on heavy-duty machinery, trucks, or equipment where clearance and grip matter, this 7/8 in socket is a reliable choice.

Practical use cases

  • Removing or tightening large suspension or axle nuts where space is limited and torque is high.
  • Maintaining heavy equipment and commercial vehicles that require robust, slip-resistant engagement.
  • Reaching recessed fasteners in engines or machinery where standard sockets can’t reach.

Why choose DeWalt for impact fasteners

  • Backed by DeWalt’s reputation for durability and precision in harsh environments.
  • Designed specifically for impact use, delivering reliable performance when it’s most needed.
  • Compatible with a wide range of 1/2 in. drive impact tools to streamline your workflow.

Practical tips for best results

  • Ensure the fastener seats fully before applying torque to maximize the 6-point engagement.
  • Pair this socket with a compatible impact wrench and avoid using it with non-impact drivers to preserve the finish and integrity.
  • Store with other deep/specialty sockets to keep the set organized and ready for the next tough job.
