Vermont Gage 111255600 Class Zz Minus Plug Pin Gage 0.5560 in

Product Description

The VERMONT GAGE 111255600 is a Class ZZ Minus plug pin gage machined to a 0.5560-inch diameter for NoGo inspection work. It is used to verify that a hole or bore does not exceed its maximum allowable size, making it a critical tool in dimensional quality control. The gage is manufactured from steel and has an overall length of 2 inches. Its tolerance is held to 0.0002 inches, consistent with Class ZZ specification. A Certificate of Accuracy with NIST traceability is included, supporting documentation requirements in calibrated inspection environments.

This plug pin gage is suited for use in machine shops, manufacturing facilities, and precision measurement labs where go/nogo inspection protocols are required. It is also compatible with setup and verification tasks involving micrometers, verniers, and other measuring devices. The compact 2-inch overall length makes it easy to handle in tight inspection setups. Typical users include quality control technicians, machinists, and metrology professionals working to ASME or equivalent dimensional standards.

Compatibility

Designed for NoGo inspection use and compatible with setup and verification of micrometers, verniers, and other precision measuring devices requiring a 0.5560-inch reference diameter.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists. Clean the gage and the bore thoroughly before use to prevent contamination that could affect measurement accuracy. Do not force the gage into a hole; light hand pressure only is appropriate for Class ZZ inspection gages. Store in the provided case or a protected location to prevent surface damage that would affect dimensional accuracy.
