Rotary Thread Inspection Tool

Patent No. 7661196
The patented Rotary Thread Inspection Tool accurately inspects internal screw threads for functional size and depth faster and easier than conventional methods. The unique Rotary Thread Inspection Tool safely checks internal threads while eliminating operator arm and hand fatigue and repetitive motion injuries. The instrument features a portable and ergonomic design engineered for industrial applications. The unit is supplied with high performance rechargeable NIMH “quick change" batteries that provide long lasting hours of operation. It also includes a patented depth control feature with automatic reversal.

Safely Inspect Parts
Out of Tolerance parts are instantly recognized. If the thread is undersized, damaged, not deep enough, or has foreign matter in the thread the gage will stop advancing into the threaded hole. This prevents damage to the part and excessive wear to the thread gage. To remove the gage, simply press the reverse button.

Eliminates Repetitive Motion Injury
The power driven gage eliminates all operator wrist motion, arm stress, hand fatigue, and repetitive motion injuries. The Rotary Thread Inspection Tool is ergonomically designed and light weight.

Flexibility
The Rotary Thread Inspection Tool accepts both standard and custom size thread taper lock style plug gages. Changing gage sizes is fast and easy. The tool accommodates a size range from #8 (.164) up to ". Other sizes can be priced upon request.

Depth Control
The Rotary Thread Inspection Tool includes a patented depth control feature that allows for the setting of a specified length or depth for the gage to travel before automatically reversing and exiting the threaded part.

Instant feedback
The Rotary Thread Inspection Tool features an “accepted" green light which indicates when the specified depth is reached before automatically reversing the gage out of the threaded part.

Power Source
The Rotary Thread Inspection Tool is powered by a special 9v Lithium rechargeable battery with a rating of 550 mAh. The battery powers the tool for up to 4 hours under normal use. The battery recharge time is 2-3 hours using the supplied charging station which charges 2 batteries at a time. The complete kit is supplied with 3 batteries for continuous use.
