Wera 8790 B Impaktor Deep Imperial Set, 13 Long Sockets with Cross Hole and Ring Socket, Color Coded

Wera 8790 B Impaktor Deep Imperial Set 1 Overview

Wera designed the 8790 B Impaktor Deep Imperial Set 1 for use with electrical and pneumatic impact drivers running at full power. The set includes 13 SAE deep sockets from 1/4" to 1”, all on a 3/8" square drive. These long sockets can reach recessed fasteners, and the high strength steel construction means they can withstand years of heavy use.

Key Features of the Wera 8790 B Impaktor Deep Imperial Set 1

Impaktor Technology

Wera's Impaktor construction uses an extremely robust forged design specifically engineered for the repeated shock loads of electric and pneumatic impact wrenches, delivering above-average service life even under extreme conditions. 

Deep 2.5” Profile

Every socket in this SAE deep socket set measures 2.5” so they can reach recessed fasteners in solar systems, structural electrical work, or other installations.

Hexagon Profile Maximizes Contact

Wera designed the sockets with a single hexagon profile to increase the contact area between the socket and the fastener. This reduces the chance of rounding.

Cross Hole and Ring Socket

The hole and ring socket make it possible to securely attach the socket to the impact driver. This critical safety feature reduces the chance of injury or damage due to a launched socket.

Color Coding by Size

Each socket includes Wera's Take It Easy color coding, so you can quickly grab the right one.

Full SAE Range

The 13 sockets cover every SAE size from 1/4" through 1" in standard fractional increments: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", and 1". 

Ideal Applications for Impact Rated Socket Sets in Renewable Energy Work

A deep impact rated socket set helps you make your renewable energy installation both sound and reliable.

• Solar panel racking and ground mount systems: Ground mount solar arrays use large structural bolts, often from 1/2" to 3/4" SAE, with significant length and protruding thread. An impact driver with deep sockets drives these faster than a hand ratchet, and the deep profile works well with the protruding thread.
• Portable generator installation and maintenance: Portable generator mounting bolts, engine hardware, and conduit connections commonly use SAE fasteners. The full 1/4"-1" range covers everything from small panel screws to large anchor bolts.
• Inverter and inverter charger mounting: Lag bolts or through-bolts often secure large wall-mounted inverter charger units, and these often benefit from impact driving. 
• Off-grid solar system structural work: Structural frames for an off-grid solar system can include SAE fasteners needing an impact wrench and deep socket set.
• Battery enclosure assembly: Deep sockets handle recessed bolt heads and protruding rods in pre-fabricated racks.
• Transfer switch and electrical panel mounting: Conduit connectors, panel mounting hardware, and structural electrical fittings often use SAE fasteners.
• Home solar kits with structural racking: Many home solar kit configurations include pre-engineered racking with SAE hardware.

Solar and Battery System Compatibility

The 8790 B Impaktor Deep Imperial Set 1 works with any solar, battery, or standby power installation using SAE hex fasteners. The deep sockets work particularly well in solar racking systems, where rail splice hardware and mid-clamp bolts often sit below the panel surface level. The hexagon profile is also significant for solar mounting hardware, which can be prone to rounding under impact.

Frequently Asked Questions About the Wera 8790 B Impaktor Deep Imperial Set 1

Can these sockets be used with a hand ratchet?

Yes. They use a standard 3/8" square drive and fit any 3/8" ratchet. 

What makes Impaktor sockets different from standard chrome-vanadium sockets?

Standard chrome-vanadium sockets are designed for hand ratchets. Impaktor sockets use a specifically forged construction to handle the shock loads of impact drivers.

Why a hexagon profile instead of double-hexagon?

A hexagon profile contacts the flat faces of the fastener head, distributing the load over a larger area. A double-hexagon profile contacts the corners and increases the risk of rounding. The single hexagon design provides a safer and more durable option for high torque environments. 

What is the cross hole and ring socket for?

These features make it possible to secure the socket to the driver so it won’t eject when used.
