Thread Checker - Set of 2

This is the perfect tool for identifying metric and imperial thread pitch on both bolts and nuts. Each gauge is clearly marked in permanent bold typeface for quick identification of the size and thread pitch. One end of each gauge checks the nuts whilst bolts can be threaded in the other end. There are 14 imperial gauges and 12 metric gauges that are conveniently assembled onto lanyard wire loops that can be hung from a nail in the workshop for fast access.

The metric thread gauges includes nut and bolt sizes of M4x0.7, M5x0.8, M6x1.0, M7x1.0, M8x1.0, M8x1.25, M10x1.0, M10x1.25, M10x1.50, M12x1.25, M12x1.5, M12x1.75 and the imperial thread gauges include nut and bolt sizes of: 6-32, 8-32, 10-24, 10-32, 1/4-20, 1/4-28, 5/16-18, 5/16-24, 3/8-16, 3/8-24, 7/16-14, 7/16-20, 1/2-13 and 1/2-20.
