Product Description

high-precision thread gauges with different types

Thread gauges can be divided into thread plug gauges and thread ring gauges, of which thread plug gauges are used to check internal threads, and thread ring gauges are used to check external threads.
Detailed explanation:
Thread plug gauge:
Used to check the correctness of the internal thread size of the workpiece.
Usually divided into through-end plug gauge (Good Plug Gauge) and limit plug gauge (Limit Plug Gauge).
Through-end plug gauge: used to check whether the effective middle diameter and major diameter of the internal thread of the workpiece meet the requirements.
Limit plug gauge: used to check whether the single middle diameter of the internal thread of the workpiece meets the requirements.
Thread ring gauge:
Used to check the correctness of the external thread size of the workpiece.
Usually also divided into through-end ring gauge (Good Ring Gauge) and limit ring gauge (Limit Ring Gauge).
Through-end ring gauge: used to check whether the effective middle diameter and minor diameter of the external thread of the workpiece meet the requirements.
Limit ring gauge: used to check whether the single middle diameter of the external thread of the workpiece meets the requirements.
In addition to the basic plug gauge and ring gauge, there are some auxiliary measuring tools:
Thread Micrometer: used to measure the thread diameter, pitch and other parameters.
Three-needle measurement method: place three cylinders with the same diameter in the thread groove, and determine the thread diameter by measuring the distance between the cylinders.
Smooth limit gauge: used to check whether the top diameter of the workpiece meets the requirements.
Common thread gauge types:
Through end thread plug gauge: complete external thread profile, check the effective middle diameter and major diameter of the workpiece internal thread.
End stop thread plug gauge: truncated external thread profile, check the single middle diameter of the workpiece internal thread.
Through end thread ring gauge: complete internal thread profile, check the effective middle diameter and minor diameter of the workpiece external thread.
End stop thread ring gauge: truncated internal thread profile, check the single middle diameter of the workpiece external thread.

Specification

Thread plug gauges are tools for measuring the correctness of internal thread dimensions. This plug gauge type can be divided into three types: ordinary coarse pitch, fine pitch and pipe thread. Thread plug gauges with a pitch of 0.35 mm or less, 2nd grade accuracy and higher than 2nd grade accuracy, and 3rd grade accuracy with a pitch of 0.8 mm or less do not have end stop probes. Thread plug gauges below 100 mm are taper shank thread plug gauges. Thread plug gauges above 100 mm are double shank thread plug gauges.

Ring gauges are also called correction ring gauges. They are circular rings with specific dimensions and properties used to correct the deficiencies of measuring tools. Ring gauges are limit gauges for shafts, mainly used to measure shafts or other external dimensions with tolerance grades of 1T6 to 1T16.
