4Pcs Screw Thread Pitch Cutting Gauge Tool Set Centre Gage 55°&60° Inch & Metric

Features: brand new and high quality Made of high-quality materials durable The thread pitch gauge is used to measure the thread pitch. It is equipped with 4 center gauges 55° inch and 60° metric. Center gauges are used to grind and position thread cutting tools on a lathe. Usually used to check the thread size to determine whether it is correct. Made of stainless steel it is not easy to rust. Ensure the accuracy of the measurement. There are 24 sheets in the metric system and the pitch of each sheet is 0.25-6mm. There are 28 pieces in inches and each piece is represented by the number of teeth per inch from 4-62 teeth. Can be used to measure metric and inch threads. The blade can also be used to measure AF threads per inch of thread. Product parameters: Type: Thread gauge Material: Stainless steel Color: silver Measuring system: metric system imperial system Quantity: 52 how to use 1) Measure the pitch Use the thread pilot group as a template to clamp the toothed steel threads on the tested workpiece. If they are not close together the other is until they fit together. Then marked on the thread size model is the measured thread pitch of the workpiece. 2) Measure the tooth profile angle Put the thread pitch and the measured workpiece thread model on the same thread for testing and then check the Thalia contact. If there is no translucent gap it is correct to measure the thread profile angle. If there is unevenness in the light transmission gap it means that the measured thread profile is not accurate. There are 24 pieces in the metric system. The pitch of each piece is 0.25-6mm. The number of pitches is: 0.25/0.3/0.35/0.4/0.45/0.5/0.6/0.7/0.75/0.8/0.9/1.0/1.25 / 1.5/1.75/2.0/2.5/3.0/3.5/4.0/4.5/5.0/5.5/6.00 There are 28 pieces in inch and each piece is represented by the number of teeth per inch from 4-62 teeth especially as the number of teeth: 4/4.5/5/6/7/8/9/10/11 /12/13/14 /16/18/19/20/22/24/25/26/30/28/32/36/40/48/60/62 Package list: 1 *52 blade thread gauge 1 *ISO Metric 60° Centering Gauge Thread Gauge Tool 1 *Inch Wyeth 55° Centering Gauge Thread Gauge Tool 1 *American Standard 60° Centering Gauge Thread Gauge Tool Note: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight manual measurement deviation for the data.
