Gedore 54 MH Spark plug insert with magnet 16 mm 1/2"

With 2 magnets for use in difficult spaces with actuating tools with 3/8" or 1/2" square drive or 8 mm diameter rotary pin. With powerful mini-magnets inside the hexagonal surface, these reliably hold the spark plug directly on the hexagon. The free receiving chamber leaves plenty of space for the spark plug and makes it easier to fit. The ceramic core of the spark plug remains untouched. Made of vanadium steel 31CrV3, chrome-plated, with precision-ground heads.
