Hexalobular Go/NoGo Gages

Hex Go/No-Go GagesHexalobular Broach gages can be used to make sure that the size of the 6-lobed (hexalobular) hole has been machined properly. Unlike rotary broaches, hexalobular broach gages have no taper. Our gages are held to tight tolerances and can be made to custom shapes and sizes. We also offer internal and external hexalobular Go / NoGo Gages.

Polygon’s broach gages are made as GO and NOGO pairs. Each gage is designed to be held by hand and inserted into the hexalobular (6-lobed) 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.

Hexalobular 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 Hexalobular 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.
