Socket bit Wera 8790 C Impaktor Deep 17 mm 1/2 drive

The Wera 8790 C Impaktor Deep 17 mm socket bit for 1/2" drive is a purpose-built tool designed to reach recessed fasteners while withstanding the high torque and shock of impact tools. Manufactured by Wera, this deep socket bit combines extended reach with impact-rated construction to work with impact wrenches and ratchets that accept a 1/2" drive. The 17 mm size fits common metric fasteners encountered in automotive repair, industrial maintenance and equipment servicing.

Advantages

This socket bit features impact-hardened steel and a corrosion-resistant finish for durability under repeated use. Its deep profile enables access to recessed or long-stud fasteners without removing surrounding components. The 1/2" drive interface ensures secure connection to impact drivers and hand-operated ratchets, while the Impaktor design reduces wear from repeated torque spikes and improves service life compared with standard socket bits.

Suitable for

• Automotive repair and wheel and brake work where fasteners sit deep on studs
• Industrial maintenance tasks requiring extra reach on machinery and assemblies
• Construction and installation jobs with recessed bolts and nuts
• Facility upkeep where impact-rated tools are used for repetitive fastening

Key specifications

• Drive size: 1/2" compatible connection for impact drivers and ratchets
• Socket size: 17 mm metric
• Profile: deep socket bit for extended reach
• Material and treatment: impact-rated steel construction with protective finish
• Intended use: compatible with impact and hand-operated drives for high-torque applications

How to use

Select the 17 mm deep socket bit and attach it securely to a compatible 1/2" drive impact driver or ratchet. Position the socket over the fastener and apply steady pressure to ensure full engagement of the bit on the nut or bolt head. When using an impact driver, operate at controlled bursts to avoid over-torquing; when using a hand ratchet, use smooth, even strokes. After use, clean off debris and inspect the socket bit for wear or damage before storage.

Usage recommendations

Use this deep Impaktor socket bit with tools rated for impact duty and observe recommended torque limits for fasteners. Replace the socket bit if signs of cracking, rounding or excessive wear appear. Store in a dry place and keep the drive connection free of grit to maintain secure coupling.
