Plain Cylindrical Plug Gage

A Plain Cylindrical Plug Gage is a type of inspection gage used in precision measurement and quality control processes. It is commonly used to check the diameter and roundness of holes or bores.

The gage consists of a cylindrical rod with a precisely machined diameter. The rod is inserted into the hole or bore being measured, and the fit between the gage and the hole is assessed. If the gage fits snugly without any play, it indicates that the hole is within the specified tolerance range. If the gage does not fit or has excessive play, it indicates that the hole is either undersized or oversized.

Plain Cylindrical Plug Gages are typically made from high-quality tool steel or carbide, ensuring durability and accuracy. They are available in various sizes and tolerance classes to accommodate different measurement requirements.

These gages are commonly used in industries such as manufacturing, automotive, aerospace, and machining, where precise measurements are crucial for ensuring product quality and performance.

In summary, Plain Cylindrical Plug Gages are precision tools used to measure the diameter and roundness of holes or bores, providing a quick and reliable method for quality control and inspection purposes.
