3. Manual Pre-tightening**: After the screw has entered the hole, manually rotate it to gradually tighten it. The purpose of manual pre-tightening is to avoid damaging the screw or misaligning the threads when using a tool. Maintain even pressure while rotating the screw by hand until it can be screwed in smoothly and the head makes good contact with the surface of the component being fastened.
4. Tighten with a Tool**: Once the screw has been pre-tightened manually, use an Allen wrench to complete the tightening process. Insert the wrench into the hex socket of the screw head, ensuring a snug fit. Then, turn the screw clockwise with even pressure. During tightening, avoid excessive force to prevent damage to the screw or the threaded hole. Ensure that the screw head is in close contact with the component's surface to achieve a secure fastening effect.
5. Check Fastening Effect**: After tightening, inspect the fastening effect. Check whether the screw is tightened properly, whether the head is in close contact with the component's surface, and whether there is any looseness. If the screw is not tightened properly or if there is looseness, retighten it immediately. Additionally, inspect the surrounding components for any deformation or other issues caused by tightening the screw to ensure the safety and reliability of the entire connection system.
(3) Removal Steps
1. Loosen with a Tool**: When removing a 304 hex socket cap screw, an Allen wrench is also required. Insert the wrench into the hex socket of the screw head and turn it counterclockwise to loosen the screw. During loosening, if the screw has not been moved for a long time or is in a humid environment, it may become rusted or seized. In such cases, apply a penetrating oil or lubricant to the connection between the screw and the threaded hole, wait for a few moments, and then attempt to loosen the screw again.
2. Manual Unscrewing**: After the screw has been loosened, manually rotate it to unscrew it partially. The purpose of manual unscrewing is to avoid damaging the screw or the threaded hole when using a tool. Maintain even pressure while rotating the screw by hand until it can be unscrewed smoothly from the hole.
3. Clean the Threaded Hole**: After the screw has been removed, promptly clean the hole to remove any debris, such as metal shavings, dust, or lubricant. Cleaning the hole prevents the accumulation of contaminants that could affect subsequent installations or usage. Additionally, inspect the threads of the hole for any damage or excessive wear. If damage or severe wear is detected, repair or replace the hole promptly to ensure its proper use.
