This handy apron pocket sized tool quickly identifies the gauge and size of a screw. The graduations read for imperial gauge screws on one side with metric on the reverse. A scale along one edge measures screw length, either countersunk or round head (although for countersunk it has to be read backwards). The imperial size gauge also recommends the pilot hole diameter. Made from stainless steel 115 x 35mm, the Axminster Screw Gauge reads for sizes 1 to 30 gauge or 1mm to 10mm metric screws.

A handy little gadgetBeside being a screw gauge it also has its uses as a 3 inch /75 mm pocket ruler. Some instructions for it's use would have been useful though.

A splendid little toolOne of the cheapest, but most useful, tools I have. With both imperial and metric scales it makes choosing a drill size to fit for example a ball catch a doddle!
