Socket wrench Wera 8003 B

The Wera 8003 B socket wrench is a slim, full-metal ratchet designed for work in confined spaces. Constructed from forged chrome-molybdenum steel and finished for corrosion resistance, it combines robustness with a fine 76-tooth ratchet mechanism delivered by a dual-tooth design. The tool includes a 3/8" push-through square and a secure socket locking function.

Advantages

The slim design permits use in very tight areas while the forged chrome-molybdenum construction provides high durability and long service life. The dual ratchet teeth form a 76 fine-pitched toothing from 38 robust teeth, enabling a small 4.7° return angle for precise operation. Direction change is simple via the non-detachable push-through square, and sockets can be held securely thanks to the locking function.

Suitable for

• Automotive repair and maintenance
• Tight or confined assembly spaces
• Workshop and professional mechanical work
• General DIY tasks requiring a 3/8" drive

How to use

Select the appropriate socket for the fastener and push it onto the 3/8" square drive until it engages with the locking mechanism. Use the ratchet handle to apply torque in the desired direction; change direction by actuating the push-through square. Because of the fine 76-tooth mechanism and 4.7° return angle, use short back-and-forth movements when working in restricted spaces.

Usage recommendations

For long service life, keep the ratchet clean and lightly lubricated at the mechanism. Use sockets rated for the same drive size and avoid applying impact loads not intended for hand tools.
