We will respond to your concerns about measuring the depth of holes and the depth of seatings with custom gauges.
The most common use of a counterbore hole is to prevent the head of a bolt from protruding when fastening structures with bolts. It is necessary to create a hole that is deeper than the thickness of the bolt head and has a larger diameter. Depending on the shape of the bolt head, it may also be shaped like a funnel. When measuring a counterbore hole, the diameter and depth are the measurement targets. <Can it be measured with calipers?> It can be easily measured using calipers. However, it is necessary to find the maximum diameter when the calipers are applied to the hole. Skill is required for accurate measurement, which means there can be variability depending on the person. Additionally, since diameter and depth cannot be measured simultaneously, two measurement actions are required. <Want to measure easily and determine pass or fail> Using a dedicated measuring instrument (gauge) allows for easy measurement. Both diameter and depth can be measured simultaneously, and it is possible to determine pass or fail at a glance. This type of gauge is portable, making it possible to measure immediately near the production line. There are various methods for determining pass or fail, including evaluating with specific numerical values or visually assessing simply, so please consult us once.
