Adjustable Limit Snap Gages

Adjustable limit snap gages provide a quick and easy attribute method of checking outside diameters, groove diameters, or width dimensions by having the go and no go elements set into the snap gage. Thread Check offers 4 assorted frame styles of snap gages with sizes ranging up to 8 5/8. Larger frame sizes are quoted upon request. The anvil gaging contacts on the snap gages are adjustable and can be set to various sizes within a range. The anvil gaging surfaces are made of hardened ground and lapped tool steel. Marking discs are supplied on all snap gages. Thread Check’s standard snap gages are progressive in design. The work piece should enter the go limit and stop at the no go limit which is towards the back. Other designs are double ended and single purpose snap gages.

The snap gage works like a fixed caliper once it has been adjusted and set to a maximum and minimum size limit. To use a snap gage the upper anvil should be used as a reference point on the work piece. The gage should be pivoted with the upper anvil acting like a hinge and the lower anvil gaging the work piece. The plane of the snap gage should be perpendicular to the centerline of the work piece. The user must be careful not to tip or angle the snap gage which could create a false measurement. Care should be taken to use gentle force when gaging work pieces with snap gages. Snap gages can be used to gauge work pieces still loaded in a machine or hand held at an inspection area. Snap gages can also be mounted in stands so that an inspector can use both hands to manage the work piece.
