ACME Thread Gages and Stub Acme Thread Gages.

the difference between Acme thread gages and Stuba acme thread gages? where can use stub acme thread gages ?
       The Major and Minor Diameter allowances for Stub Acme threads are the same as those given for General Purpose Acme threads. Pitch Diameter allowances for Stub Acme threads are the same as for Class 2G General Purpose  Stub Acme thread Plug Gages and Ring Gages are used for thin walled applications, where coarse pitch is needed like tubes used in Oil fields equipments, where standard ACME threads can not be used due to thin wall.

• Gauge dimensions for Acme threads are as per ASME B1.5 and Stub Acme as per ANSI/ASME B1.8

• Most commonly used class is 2G. If less backlash is desired in acme threads, 3G & 4G class are used

• The height of Acme threads is 0.5p, whereas the height of Stub Acme threads is 0.3p

SOWANT provides a complete line of standard and special General Purpose ACME GO/NO GO Thread Plug Gages in compliance with ASME B1.5 - 1997. Acme Thread Plug Gages are used to gage an internal threaded product.. The ACME thread list of diameters listed here and their associated pitches are recommended as preferred. They have been specifically selected to meet requirements with the least number of items. In doing so this keeps the inventory of gages and tooling to a minimum in an effort to reduce costs.

There are three classes of fit for ACME General Purpose thread gages; 2G, 3G and 4G. Centralizing ACME threads have classes of fit which are 2C, 3C and 4C. ACME threads feature a 29 degree angle of thread which is the angle between the sides of the thread measured in an axial plane. ACME Thread Plug Gage lengths and blank standards are compliant to ASME B47.1 Centralizing ACME thread gages, Multiple start ACME thread gages and any special requirements will be priced on request.

All ACME Thread gages are made in China, Delivery time:about 4 week,  you should tell us DHL/FEDEX/UPS account , it will ship to you in 1 weeks around.
