Hexagonal hollow screws, also known as hex head set screws, are designed with a hexagonal head and a hollow shaft. The hollow design allows for the passage of wires, cables, or other components through the screw itself, which can be particularly useful in applications where space is limited or where components need to be routed internally. These screws are typically used for securing components in place, especially where a flush finish is required.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

Space Saving: The hollow shaft saves space and allows for the passage of wires or cables, making them ideal for applications with limited space or where cable management is required.Easy Installation: The hexagonal head allows for easy tightening with a wrench or an Allen key, ensuring a secure fit.Versatility: They can be used in a variety of applications, including machinery, equipment, and furniture assembly.Corrosion Resistance: Often made from stainless steel (304/316), these screws offer excellent resistance to rust and corrosion, making them suitable for outdoor use or in humid environments.Aesthetics: The hex head provides a clean and finished look that is suitable for both functional and aesthetic applications .

Scope of 

Application

Machinery and Equipment: Used in machinery frames and equipment where a secure and adjustable connection is needed.Furniture Assembly: Employed in furniture that requires frequent disassembly and reassembly.Construction: Utilized in building structures where a secure connection is required.Automotive Industry: Used in the assembly of vehicles where a secure and aesthetically pl

easing connection is needed.Electronics: Ideal for electronics where tool-less adjustments are needed.
