The Proxxon MICRO compact ratchet is an industrial quality ratchet designed for professional use. Having 1/4''square drive with an extremely slim head only 23 x 12mm and overall length of 120mm, it enables you to work in places where space is tight. The fine 72-tooth ratchet allows movement in the narrowest spots and is capable of transferring high torque. The head has a release mechanism, which unlocks sockets at the push of a button. Double nickel-plating and a matt chrome plated finish give the CrV steel forging maximum protection. The grip is an oil and acid resistant TPR (thermoplastic rubber) with a practical hanging hole.
