AI Technical Summary
Existing screws, such as pan head and flat head screws, either completely fix boards or fail to provide a secure feeling of being screwed in, lacking an intermediate option for partial fixation.
A screw design with a head diameter smaller than the threaded portion, combining features of both pan and flat head screws, allows for partial fixation of boards.
Enables secure fastening of boards with a sense of proper screwing, intermediate to complete fixation, addressing the limitations of existing screw types.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a new screw. [Background technology]
[0002] Reference 1 has been withdrawn. A pan head screw is a screw with a pan head. A screw is a headless screw. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent application 2022-175852 Summary of the Invention [Problem to be solved by the invention]
[0004] When fixing a board with a pan head screw, the board will be completely fixed due to the screw head. Also, when using a flat head screw, you may not get the feeling that it is screwed in properly. DETAILED DESCRIPTION OF THE INVENTION
[0005] By using screws with a head diameter smaller than the diameter of the threaded portion (screws that are somewhere between pan head screws and flat head screws), the boards can be fastened together with the feeling of using a pan head screw.
[0006] You can screw the board in place without completely fixing it, just like using a pan head screw. [Example]
[0007] Plates and other objects are fastened using a pan head screw, which is somewhere between a pan head screw and a flat head screw, and has a pan-shaped head with a smaller diameter than the threaded part. An example of a pan head screw is shown in Figure 1. [Brief explanation of the drawings]
