Socket Bit Wera 8790 C Impaktor Deep 13 mm 1/2 drive

The Wera 8790 C Impaktor Deep 13 mm socket bit for 1/2" drive is a long, impact-rated socket accessory engineered for heavy-duty fastening tasks. Its extended length allows access to recessed or hard-to-reach 13 mm fasteners while the Impaktor geometry and durable material composition are designed to withstand high torque from impact wrenches and pneumatic or electric drivers. The tool combines reach, strength and a secure fit for reliable operation in automotive, industrial and maintenance environments.

Advantages

The deep profile provides extended reach to access bolts located in narrow or recessed spaces without compromising fit. The Impaktor design reduces stress concentration at the socket-workpiece interface, increasing resistance to shock loads and improving service life under repeated impact use. Manufactured to precise dimensions, the socket bit ensures a tight fit on 13 mm fasteners to minimise rounding and slippage. The 1/2" drive connection offers compatibility with a wide range of impact ratchets and wrenches commonly used in professional workshops.

Suitable for

• Automotive repair and wheel service where recessed nuts or bolts require extra reach
• Industrial maintenance on machinery with hard-to-access fasteners
• Construction and plant service tasks using 1/2" impact tools
• General workshop use with impact drivers and ratchets

Key specifications

• Drive size: 1/2" compatible connection for impact tools
• Socket size: 13 mm for corresponding hex fasteners
• Type: Deep socket bit for access to recessed fasteners
• Designed for: Impact use and high-torque applications
• Material/finish: Impact-rated hardened steel (industrial-grade)

How to use

Select the 13 mm Wera Impaktor deep socket bit and securely attach it to a 1/2" drive impact wrench or ratchet. Position the socket over the fastener ensuring full engagement on the flats before applying torque. When using an impact tool, apply controlled bursts rather than continuous full-throttle operation to maintain control and reduce the risk of over-torquing. After use, inspect the bit for wear or deformation and clean any debris to preserve fit and function.

Usage recommendations

Use the socket bit only with compatible 1/2" impact-rated drivers and avoid using with non-impact hand tools in applications outside the intended torque range. Store in a dry, organized toolbox to prevent corrosion and to quickly identify the 13 mm deep Impaktor bit when needed.
