Ingco Socket Spanner 20mm HHAST12201

Our review

This is a single 20mm socket from Ingco, built for a 1/2 inch drive tool such as a ratchet handle or breaker bar. The six-point opening grips the flats of a bolt head rather than the corners, which matters on fasteners that are tight or already slightly worn. Ingco applies heat treatment and a black nickel plating, so the socket is made to resist corrosion and take repeated use in a workshop or on a vehicle. It suits someone who already owns 1/2 inch drive tools and needs this specific size, not a buyer starting from nothing. Before ordering, confirm your handle or extension is 1/2 inch drive, and check the bolt you are working on is genuinely 20mm rather than an imperial size that sits close to it. Compare against other 20mm sockets on drive size, point count and finish, since those are the differences that affect fit and lifespan.
