A set consists of two wheels, an axle and crank pins where appropriate (available separately as Ref: 7802). We have a large range of wheels to fit most types of locomotives and the range is growing continuously.

A wheel consists of a brass centre bush, nylon moulded wheel (so no problems with insulation) and a steel tyre.

Standard Driving wheels have square ended axles for easy quartering. Outside crank wheels now have a square on the extended end of the axle, and a matching crank (Ref:X720053G) is included with the wheel set. We still have stocks of the old "D" shaped axle if required.

All locomotive wheels are to Fine Standard ("Finescale") profile with a back-to-back of 29.2mm. We also make and can supply axles for Scale7 b-b (Ref: X78002S), and also for several broad and narrow gauges.

Most 7mm scale wheels are secured using an Allen Key which is 1.27mm A/F (see item X78001) except those which have 1/8" diameter axles, these are secured with an Allen Key which is 0.89mm A/F (see item X78003).

All axles are 3/16" (4.763mm) diameter unless otherwise stated.
