Socket wrench Wera 8004 A

The Wera 8004 A Socket wrench is a single-piece, full-metal ratchet made from chrome-molybdenum steel with a chrome finish. Its slim design enables work in confined spaces while offering high robustness and long service life. The ratchet features 72 fine-pitched teeth for a small 5° return angle and includes a switchover lever for convenient direction changes plus a secure socket locking function.

Advantages

The 72-tooth mechanism ensures precise incremental movement with a 5° return angle, improving access in tight areas. A switchover lever allows quick and secure reversal of direction, and the socket locking function keeps sockets attached during use. Chrome finish offers corrosion resistance and easy cleaning.
