Vermont Gage 911107800 Class Zz Plus Plug Gage 0.078 in

Product Description

The VERMONT GAGE 911107800 is a Class ZZ Plus plug gage designed to measure a nominal diameter of 0.078 inches with a tolerance of 0.0002 inches. Manufactured from tool steel with a black oxide finish, it provides corrosion resistance and durability under regular shop-floor use. The gage ships with a Certificate of Accuracy that includes NIST traceability, meeting ASME B89.1 standards. Machinists, quality control technicians, and tool room professionals use this gage to verify hole sizes quickly and reliably during go inspection routines.

This plug gage is suited for go inspection applications including the checking of drilled, reamed, or punched holes in production and tool room environments. It is also used as a reference standard when setting micrometers, verniers, and other measuring devices that require a precise known dimension. The 0.078-inch diameter range serves small-hole inspection tasks common in precision machining and light manufacturing. Overall length is 2.0 inches, keeping it manageable for bench and in-process use.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise small-hole go inspection
• Tool steel construction for hardness and dimensional stability
• Black oxide finish for corrosion resistance and reduced glare during inspection
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compact 2.0-inch overall length suited for bench and production floor use

Compatibility

Designed as an OEM-style go plug gage for use in go inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 0.078-inch nominal diameter reference.

Installation Notes

Plug gages of this type are handled and used by quality control technicians and machinists. Store the gage in its protective case when not in use to prevent nicks or corrosion that would affect dimensional accuracy. Handle with clean, dry hands or cotton gloves to prevent oils from affecting the finish and surface. Do not force the gage into a hole; apply light, consistent hand pressure only to avoid wear or damage to the gage or workpiece.
