The Proxxon metric 1/4" socket spanner set is a versatile tool set that has been specially designed for working on long threaded bolts and screws. Equipped with a reversible ratchet, this set enables efficient handling and a high level of user comfort. The TPR (Thermoplastic Rubber) handle ensures non-slip and comfortable handling, while the 55 mm extension can also be used in open construction methods. The supplied adapter with 1/4 square (6.3 mm) extends the range of applications for the set. All parts are housed in a sturdy, powder-coated steel box, which contains a strong plastic mould insert to store and transport the tools safely. The use of high-quality chrome vanadium steel for the ratchet head and shaft ensures durability and resistance.
