Outer hexagonal hollow screws, also known as hex head hollow screws, are a type of fastener 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.
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 provides a good platform for tightening with a wrench or an Allen key, ensuring a secure fit.Versatility: They can be used in a variety of applications, including electrical, mechanical, and structural assemblies.Corrosion Resistance: Often made from stainless steel (304/316), these screws offer excellent resistance to rust and corrosion, 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
Lamp Lighting: Widely used in lamp lighting for socket expansion and fixing ceiling chandeliers or other lamps.Electrical Accessories: Employed in electrical accessories for securing components while allowing the passage of wires or cables.Machinery Manufacturing: Utilized in machinery manufacturing for applications where a secure and adjustable connection is needed, with the added benefit of internal routing for cables.DIY Handmade Ornaments: Ideal for DIY projects where a compact and secure fastening solution is required, and cable management is necessary.Electronics: Used in electronics for securing components while allowing for the passage of wires or cables.
