Imperial & Metric Nut Size Checker / Gauge by CanFire Jan 23, 2013

Description

Printable gauges that you can press-fit hex nuts into and use to check your bolt collection. You could leave bolts in as well and then check both nuts & bolts.

There is a 7.5mm tall recess below each row of openings for fixing labels.

For Imperial, the gauge is designed for the following nuts: 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, 1/2"-20

For Metric, the gauge is designed for the following nuts: M2x0.4, m2.5x0.45, M3x0.5, M4x0.7, M5x0.8 M6x1.0, M8x1.0, M8x1.25, M10x1.0, M10x1.25

Each gauge is less than 100mm wide so they should be printable on just about every printer.

EDIT Jan 23, 2013: Sorry folks. The MetricNutSizeChecker.STL file that was initially uploaded was the wrong version. The correct one is posted now.

EDIT Jan 25, 2013: Information on nut dimensions was obtained from: http://www.engineershandbook.com/Tables/nuts.htm

Instructions

I printed mine with 50% fill, 0.4mm width, and 0.25mm layer height. The nuts are a tight press fit and did not require glue.

I would like it if it already had the sizes.
