A set of pass-through sockets and accessories. All sockets are spline type which means they have a ridge in the centre of the side wall and contact the fastener at the approximate midpoint of the side. This specialised shape makes it possible to match sockets to hexagonal, dodecagonal, torx, spline, square and inch size nuts and bolts. The ratchet, sockets and accessories are pass-through, enabling work with long pins (shock absorbers).
