Technical Specifications:

• Length: Varies according to application, typically ranging from 1 inch to several feet.
• Thread Type: Full or partial threads on both ends, which can be coarse or fine, depending on the material it is intended for.
• Material: Commonly made from steel, stainless steel, brass, or other corrosion-resistant metals.
• Finish: Available in different finishes, including zinc-plated, nickel-plated, or black oxide for corrosion resistance.
• Head Type: Generally does not have a head; some models may have a small hexagonal or flat section for installation.
• Diameter: Varies, typically from 3mm to 12mm, depending on the specific application.
• Usage: Often used with nuts or other fastening elements on either side.
• Strength: Usually rated based on the tensile strength and material grade (e.g., Grade 5, Grade 8, or stainless steel).

Features:

• Dual Threading: Both ends of the screw are threaded, making it ideal for fastening components or parts from two different directions.
• Versatility: Suitable for use in a wide variety of materials such as metal, wood, or plastic.
• Durability: Available in corrosion-resistant finishes and materials to ensure long-lasting use in harsh environments.
• No Head: Lacks a head, allowing it to fit into tight spaces and be used in applications where a head would interfere with installation.
• Customizable: Available in various lengths, diameters, and materials to fit specific needs.

Uses:

• Woodworking: Double-ended screws are often used in furniture making and woodworking projects, particularly for joining parts together or when fastening components in a concealed manner.
• Construction: Commonly used in construction for connecting elements like wall studs, beams, or securing posts to foundations or frames.
• Automotive: Used in the automotive industry for fastening engine components, chassis parts, or even attaching trim pieces where dual fastening points are necessary.
• Furniture Assembly: Ideal for assembling components in cabinets, tables, and other furniture where a flush finish is desired, and the screw is hidden within the joints.
• Machinery and Equipment: In mechanical assemblies, double-ended screws are used to fasten parts securely and are often paired with nuts on each end to hold the parts in place.
• Electrical and Plumbing Applications: Used for mounting and fastening electrical panels, pipes, and other infrastructure components that need secure fastening from both sides.
