Wood screws: Used to fasten materials such as wood and plastic, they have sharp, tapered heads that use rotational friction to securely join materials together.
Self-tapping screws: Used to fasten metal, they have a special helical shape and sharp heads that allow cutting into material and securing it without pre-drilling.
Hex bolts: With a hexagonal structure at one end, they are suitable for applications requiring frequent adjustment, disassembly, and installation of fasteners.
Screws are common fasteners composed of multiple parts. Different screw types have their own unique structures and applications. Understanding the structure and characteristics of screws allows for better selection and application of suitable screws, improving the efficiency and accuracy of fastening operations.
