Glastonbury Gage ITC Internal Thread Gage Comparator Variable Thread Gage

The Glastonbury Southern ITC Internal Thread Comparator gives you actual thread measurement of dimensional characteristics for quicker machine adjustments and reduced gaging time over thread plug gages. One single gage can be used to check pre-plate, after-plate, class 2, 2B, 3, and 3B eliminating the need for multiple fixed limit thread plug gages. A single frame covers a size range from #10 through 2 ½ in diameter. Larger frames are available up to 8.0″. The rigid construction and constant measuring pressure of our ITC comparators provide consistent and accurate readings

These units consist of five components
1. Bases & Accessories
2. Frames
3. Dial Indicator
4. Stop Adjusting Tool
5. Gaging Rolls – Inch

• Quick setting with the use of a master setting ring
• Easy to setup

SYSTEM 21
System 21 provides for interchangeable assembly with respect to functional size only. Functional size must be measured at the maximum material limit within the length of standard gaging elements. The characteristic known as NO GO functional diameter must also be verified. This can be accomplished by using fixed limit gaging or variable gaging with functional elements.
SYSTEM 21A (FOR METRIC THREADS IN ACCORDANCE WITH ANSI B1.18M)
System 21A provides for interchangeable assembly with functional size verified at the maximum material limit using standard length gaging elements. This can be accomplished using fixed limit gaging or variable gaging with functional elements. System 21A also states that the minimum material limit (minimum pitch diameter) must be verified by inspecting two thread flank locations over the length of the thread. This can be accomplished by using variable gaging or thread roll snap gages with pitch diameter elements.
SYSTEM 22
System 22 provides for the interchangeable assembly with functional size verified at the maximum material limit using standard length gaging elements. This can be accomplished using fixed limit gaging or variable gaging with functional diameter elements. System 22 also states that the minimum material limit (minimum pitch diameter) must be verified over the full length of the thread. This can be accomplished using variable gaging with pitch diameter elements.
SYSTEM 23
System 23 provides for interchangeable assembly with functional size verified at the maximum material limit using standard length gaging elements and minimum material limit (minimum pitch diameter) must be verified over the full length of the thread. The gaging requirements for SYSTEM 22 would also apply here but in SYSTEM 23 other thread characteristics such as lead, flank angles, taper and roundness must have to be independently verified. Only thread characteristics, which are specified, will have to be inspected for SYSTEM 23 compliance.
