When screw connections are deep, profiles are special or there is hardly any room for a normal spanner, socket wrench sockets are the solution. Instead of improvising, professionals reach for the right socket wrench socket - matched to the drive, profile and application. Hex socket wrench sockets, bi-hex socket wrench sockets, Spline-Drive socket wrench sockets and TORX® socket wrench sockets are available for classic screw connections - in 1/4", 1/2‘, 1’ and common sizes such as 13 mm, 17 mm and 34 mm socket. The articulated versions, such as uniflex sockets or Spline-Drive uniflex sockets, make it easier to work in confined engine or machine compartments. For plumbers and building services engineers, there are standpipe wrench sockets, sockets for standpipe wrench, angle valve spanners, multi-purpose valve spanners and S-connection assembly tools - optimal for fittings, angle valves and S-connections where pipe wrenches reach their limits. In the automotive sector, oil filter wrenches, oil filter tools, universal oil filter wrenches and spark plug socket wrench sockets support quick servicing of oil filters and spark plugs. Special crowfoot wrenches, crowfoot socket wrench sockets, crowring socket wrench sockets and 4-pin sockets open up hard-to-reach or exotic profiles, for example on hydraulics, valves or industrial plants. STAHLWILLE socket wrench sockets thus cover everything from classic socket wrench sockets to specialised solutions for workshops, industry, automotive engineering and building services.
