Fastener

A fastener is a hardware component designed to mechanically join or non-permanently secure objects. They are broadly categorized by the manner in which they are applied and removed, and can be broadly divided into two main types: permanent and temporary.

Materials

Fasteners are produced from a wide range of materials, selected based on application requirements such as strength, corrosion resistance, temperature, and cost. Common materials include:

• Steel: Carbon steel is frequently used for general purpose applications. Alloy steels offer increased strength and resistance to corrosion and temperature extremes. Stainless steel provides excellent corrosion resistance.
• Aluminum: Lightweight and corrosion-resistant, often used in applications where weight is a concern.
• Brass: Corrosion resistant and machinable, frequently used in plumbing and electrical applications.
• Titanium: High strength-to-weight ratio and exceptional corrosion resistance, used in aerospace and medical applications.
• Plastic: Used in applications where corrosion resistance, electrical insulation, or low weight are important.
• Nylon: Lightweight and corrosion-resistant, often used in low-stress applications.

Purpose and Function

The primary purpose of a fastener is to create a clamping force between two or more objects, holding them together. This clamping force is achieved through various mechanisms, including:

• Friction: The force resisting relative motion between the joined surfaces.
• Compression: Applying a force to squeeze the joined objects together.
• Interference: Using a tight fit to hold the objects together.

Usage Scenarios

Fasteners are ubiquitous and used in virtually all industries and applications, including:

• Construction: Securing structural components, cladding, roofing.
• Automotive: Assembling vehicle components, engines, body panels.
• Aerospace: Joining aircraft structures, engines, interior components.
• Electronics: Securing circuit boards, enclosures, connectors.
• Furniture: Assembling wood and metal furniture components.
• Plumbing: Connecting pipes, fixtures, and appliances.
• Manufacturing: General assembly of products and equipment.

Common Types

Fasteners are available in a wide variety of types, each suited to specific applications. Some common types include:

• Bolts: Threaded fasteners with a hexagonal or square head, typically used with a nut.
• Screws: Also threaded fasteners, but typically self-tapping or used with a pre-threaded hole. Available in a wide range of head styles (e.g., flat, round, pan, oval).
• Nuts: Used in conjunction with bolts or screws to create a clamping force.
• Washers: Used under the head of bolts or screws to distribute the load and prevent damage to the joined surfaces.
• Rivets: Permanent fasteners that create a strong, irreversible joint.
• Pins: Used to align or secure components, often used as hinges or pivots.
• Clips: Temporary fasteners used to hold components together.
• Anchors: Used to secure objects to concrete, brick, or other masonry materials.
• Toggle Bolts: Used to secure objects to hollow walls.
• Self-Drilling Screws: Combine drilling and fastening in one step.

Standardization

Fastener dimensions and performance characteristics are often standardized by organizations such as:

• ISO (International Organization for Standardization): Provides international standards for fasteners.
• ANSI (American National Standards Institute): Develops standards for fasteners in the United States.
• DIN (Deutsches Institut für Normung): German standards institute that also publishes fastener standards.

Fasteners encompass a range of products designed to mechanically join or secure materials. Based on the provided information, several HS codes may be relevant depending on the specific type of fastener.

• 7318152095: This HS code covers screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, and washers (including spring washers) of iron or steel. Specifically, it applies to threaded articles – other screws and bolts, whether or not with their nuts or washers, having shanks or threads with a diameter of <6 mm, and further categorized as "Other: Other: Other". The basic duty is 0.0%, with an additional 25.0% duty, increasing to 30.0% after April 2, 2025. A 25% additional duty applies to steel and aluminum products. The total duty rate is 80.0%.

• 7317006530: This HS code covers nails, tacks, drawing pins, corrugated nails, staples (other than those of heading 8305), and similar articles of iron or steel, whether or not with heads of other material, excluding those with copper heads. It specifically applies to "Other: Of one piece construction: Other Cut". The basic duty is 0.0%, with an additional 25.0% duty, increasing to 30.0% after April 2, 2025. A 25% additional duty applies to steel and aluminum products. The total duty rate is 80.0%.

• 8308100000: This HS code covers clasps, frames with clasps, buckles, buckle-clasps, hooks, eyes, eyelets and the like, of base metal, of a kind used for clothing or clothing accessories, footwear, jewelry, wrist watches, books, awnings, leather goods, travel goods or saddlery or for other made up articles. It specifically applies to hooks, eyes and eyelets. The basic duty is 1.1¢/kg + 2.9%, with an additional 25.0% duty, increasing to 30.0% after April 2, 2025. A 25% additional duty applies to steel and aluminum products. The total duty rate is 1.1¢/kg + 2.9% + 55.0%.

• 8308909000: This HS code covers other clasps, frames with clasps, buckles, buckle-clasps, hooks, eyes, eyelets and the like, of base metal, including parts. The basic duty is 2.7%, with an additional 25.0% duty, increasing to 30.0% after April 2, 2025. A 25% additional duty applies to steel and aluminum products. The total duty rate is 57.7%.

According to the provided reference material, the HS code options related to 'fastener' are limited, with only the following 4 found. It is important to determine the precise material composition (iron or steel) and intended use of the fastener to select the correct HS code.
