The flash tester, as an efficient precision measuring device, is widely used in the measurement of workpieces of various sizes and shapes, especially in the measurement of screw dimensions, its accuracy and convenience are particularly outstanding.

I. Diameter measurement

1. screw large diameter (OD): the largest diameter of the screw, and usually the main contact surface of the screw connection. With its high-precision optical system, the Flash Meter is able to quickly and accurately capture the size of the screw's major diameter, ensuring the accuracy of the measurement results.

2. small diameter (root diameter): the diameter of the bottom of the screw groove, this measurement is critical to assessing the strength and durability of the thread. The Flash Meter also makes this measurement easy, providing accurate root diameter data.

II. Length Measurement

1. total length: the overall length of the screw workpiece, including the screw part and non-threaded part. Flash meter through its efficient measurement algorithm, can accurately measure the total length of the screw workpiece, for subsequent processing and assembly to provide reliable data support.

2. screw part length: only the length of the screw part is included. The measurement of this dimension is important to ensure the stability and reliability of the screw connection. Flash meter can accurately measure the length of the screw part, for the design and optimization of the screw connection to provide strong support.

III. Pitch Measurement

Distance between adjacent thread peaks: In metric screws, pitch refers to the distance between two adjacent thread peaks. Flash meter through high-precision measurement technology, can accurately measure the pitch of metric threads, for screw processing and inspection to provide an important basis.

IV. Head Size Measurement

For the threaded workpiece with a screw head, the flash meter can also measure its head size, including the diameter of the screw head, height, and the size of the slot or cross slot. The measurement of these dimensions is important to ensure the correct installation and use of the screw head.

V. Thread Angle Measurement

Screw angle is an important parameter of the screw, which determines the shape and connection of the screw. Flash tester can accurately measure the angle of the screw.
