subject: How To Use The Combo Gauge [print this page] Combo Gauge The Combo Gauge is used for sizing inch and metric bolts, screws, drill bits & rivets. The Combo Gauge consists of these three different gauges assembled as one:
- Top gauge (red) is a rivet gauge for sizing pop rivets.
1. For sizing pop rivets from #3 to #8 diameters and blind threaded inserts from 6-32 to 3/8.
2. This tool also has a handy 5 ruler.
- Next gauge (white) is an internally threaded screw gauge.
1. This gauge is in inch and metric. You can actually screw fasteners into this gauge.
2. Size range is from #0 coarse and fine thread, and the metric range is from 1.6mm to 16mm
3. The reverse side is a drill and tap gauge for the corresponding holes.
- Last gauge (blue) is the drill gauge.
1. Used to size drill bits in fractional or metric.
2. 7 1/2 ruler
The combo gauge is made of sturdy plastic and is water, alcohol, oil & grease resistant. It spreads apart and closes back up to make it a very informative, but compact and user friendly reference tool.
HOW TO USE THE Combo GAUGE:
Please refer to the numbers on the reference chart
1 Slide the body of the rivet into the corresponding slot it fits into. This will give you the diameter of the rivet. Then use the numbers to the right of the slot to give you the overall body length of the rivet you are sizing.
2 Use the holes on the rivet gauge to the right to size the diameter of the rivet body.
3 Use the holes across the bottom of the rivet gauge to size the diameter of blind threaded inserts.
4 Use the internally threaded screw gauge to check the threads and determine what your fasteners is, weather it is inch or metric, coarse or fine thread. You can actually thread your fastener into this gauge for precise reference.
5 Use the drill gauge to size drill bits in fractional or metric dimensions.
6 The drill gauge also has a 7 for measuring purposes.
