Thread plugs are machined Go/No-Go gages that contain external threading machined to a very specific thread size. They are used for checking 

A thread gauge is used to check the dimensions of a specific thread form angle, pitch and diameter. Plug gauges are used to check internal 

2017. 11. 30. · TYPES OF THREAD GAGES THREAD PLUG GAGE – GO AND NO-GO. This type of thread gage is used to check the acceptance of an internal threaded part, otherwise referred to as a nut. For smaller threaded parts, the thread plug gage will consist of two ends, one end with a GO gage and another with a NO-GO gage.

The Go end of thread plug gage checks the smallest size of pitch diameter D2,the smallest size of major diameter.It also check some thread deviation, for example, pitch, thread profile angle deviation. The go end should go through the whole thread without using force. the Nogo end of plug gage checks the largest size of pitch diameter.

Straight Pipe Thread Plug Gages. Straight pipe working plug gages are used to check the size of the internal threads of a part. Straight pipe setting plug gages calibrate and set a straight pipe thread ring. Setting plug gages inspect the ring gage for wear. GO or NOGO members. Precision hand lapped to provide optimum finish and superior accuracy.

1.Thread plug gauge and thread ring gauge all packed with standard plastic tool box,if you need customized boxes,pls inform us in advance. 2.the tool box packed with Pearl cotton,then in carton box,if for big heavry product,we will packed with wooden box. Certificate,

A Standard Thread Plug Gage refers to an inspection tool used to check a workpiece against its allowed tolerances via a go/no-go test. For example, ISO 1502 sets a standard for screw threads and gaging to test them. It establishes the attribute T as go for the major diameter and the attribute Z as no-go for the pitch diameter.

Straight pipe plug gauges are used to check straight pipe threads such as NPSM, NPSF, and BSPP thread types. Threaded Go gauges and No-Go plugs test if the internally threaded pipe is within tolerance by checking if the gauges mate cleanly with the threads. Tapered pipe thread plug gauges use L-1, L-3, and 6-Step gauges to perform similar

Thread Plug Gauges are used to check inside major diameter and pitch diameter limits on threaded parts. Thread ring gages are adjustable and used to measure 

These threaded plug gauges are used to check and inspect internal inch threads in Unified thread standards including Unified Coarse (UNC), Unified Fine
