Hexagon Go/No-Go Gages

Hexagon Broach Gages can be used with Polygon’s standard ASME broaches to make sure that the size of the hexagon hole has been machined properly. Unlike rotary broaches, hex broach Gages have no taper. Our Hexagon Gages are held to tight tolerances and can be made to custom shapes and sizes. We also offer external hexagon go / nogo gages.

Polygon’s hex broach Gages are made as GO and NOGO pairs. Each gage is designed to be held by hand and inserted into the hexagon hole. If the NOGO Gage fits, then the hole is too large and the part fails inspection. If the GO Gage fits, then the hole is the right size and the part will pass inspection. If the hole was too small the GO Gage would not have fit inside.

Hex Gages can also help to determine if there is too much twist in the form, a common troubleshooting feature of holes manufactured using the rotary broaching process. Our Hexagon Broach Gages are made of durable hardened M-2 tool steel. All Gages come with handles featuring green caps on the GO Gage side and red caps on the NOGO side.

** GO and NOGO hex Gages can easily be customized. Call us with your dimensions at 239-628-4800. Custom hex Gage delivery requires 2-3 days for manufacturing.
