Plug Thread Gauges.

What are Plug Thread Gauges?

Plug Thread Gauges, also known as thread plug gauges, are precision tools used to verify internal thread dimensions. Featuring a hardened steel body with threaded sections matching specific thread sizes and pitches, they ensure threads meet exacting standards for seamless assembly. Using plug thread gauges guarantees your products meet precise standards while eliminating costly errors.

How Plug Thread Gauges Work.

Using a thread plug gauge is simple: insert the "Go" end into the threaded hole, it should fit smoothly if the thread is within tolerance. The "No-Go" end should not fit, confirming the thread isn't oversized.
This Go/No-Go method allows quick, accurate assessments of internal threads, keeping production efficient. Plug thread gauges are essential in precision-critical industries like aerospace, automotive and medical devices.

Materials Plug Thread Gauges are Made From.

Made from premium hardened steel, all of our plug thread gauges offer exceptional durability and wear resistance, maintaining precise measurements even after extensive use.

Size and Type of Plug Thread Gauges Available.

Our range includes plug thread gauges from tiny M1 metric and 1 1/2 - 6 UNC imperial threads up to M150 metric and 12-24 UNC imperial threads.
Additional Thread Gauges are available or use with less common thread types such as British BSW and BSF threads, NPT and NPTF pipe threads, and German PG threads. Whatever your project scale, we have the right thread plug gauge.

Choose from Go, No-Go and combined Go/No-Go gauges, plus right-handed and left-handed variants, covering most threading configurations. Each thread plug gauge is precision-engineered for accuracy and reliability, helping you maintain the highest standards.

FAQs.

Q: What is a Plug Thread Gauge?.

A: Plug Thread Gauge is a precision tool used to inspect the internal threads of a hole. Made from hardened steel, it checks that thread dimensions meet specific size and pitch standards. This ensures seamless assembly with matching external threads.

Q: What are the Advantages of Plug Gauges?.

A: Plug gauges provide precise measurements to verify thread specifications. They enhance quality control by detecting threading errors early. Easy to use and available in various sizes and types, they improve efficiency in manufacturing.

Q: How to Properly Use a Plug Thread Gauge?.

A: Choose the correct gauge size and type for your thread. Insert the "Go" end into the threaded hole; it should fit smoothly without force. The "No-Go" end should not fit, confirming the thread is within acceptable tolerances.

Q: How Accurate is a Plug Gauge?.

A: Plug gauges are highly accurate tools manufactured to strict standards. They maintain precise measurements even after extensive use because of their hardened steel construction. Regular calibration ensures they provide reliable results in quality control.
