Non-standard screws are tools that utilize the physics and mathematical principles of circular rotation and friction on an object's inclined plane to progressively secure mechanical components. Screws are a general term for fasteners, commonly used in everyday colloquial speech. Screws play a crucial role in the industry, and as long as there is industry on Earth, the function of screws will always remain important.

Diameter Measurement:

The diameter of a non-standard screw refers to the threaded portion of the screw, but screws come in full-thread and half-thread variations. Full-threaded screws can be measured directly in the middle of the screw, while half-threaded screws also require measurement of the polished shank. The measurement method is as follows:

Head Thickness Measurement:

We generally measure the heads of non-standard screws, typically flat-head screws and external hex screws, while other types of screws are usually produced according to specifications.

Measure the size of the measuring head:

Generally, head size testing is required for non-standard screws, particularly non-standard and irregular-shaped parts.

Length Measurement:

There are two methods to measure the length of non-standard screws. One is the countersunk screw measurement: from the tip to the end of the entire screw. The other螺丝from the bottom of the head to the tail.

Slot Depth Measurement:

The measurement of the groove depth is also essential. The groove depth of non-standard parts can be adjusted according to customer requirements.
