Door Bolt
A door bolt is a fastening mechanism used to secure a door, typically supplementing a latch for increased security. It generally consists of a metal bar that extends horizontally or vertically to engage with a strike plate on the door frame.
Material
Door bolts are commonly constructed from the following materials:
- Steel: Offers high strength and resistance to forced entry. Often coated for corrosion resistance.
- Brass: Provides corrosion resistance and a decorative finish. Less resistant to force than steel.
- Aluminum: Lightweight and corrosion resistant, suitable for interior applications.
- Stainless Steel: Offers excellent corrosion resistance and durability, appropriate for both interior and exterior use.
Purpose
The primary purpose of a door bolt is to provide enhanced security against unauthorized entry. They offer a stronger hold than standard door latches, making them more difficult to force open.
Function
A door bolt functions by physically obstructing the door from being opened. When engaged, the bolt extends into the door frame, creating a rigid connection. Disengagement requires a key, thumb turn, or other actuation mechanism.
Usage Scenarios
Door bolts are used in a variety of settings:
- Residential: Securing exterior doors, shed doors, and gates.
- Commercial: Reinforcing doors in businesses, warehouses, and storage facilities.
- Interior: Securing rooms for privacy or safety (e.g., bathrooms, bedrooms).
- Security: Providing an additional layer of protection against break-ins.
Common Types
Several types of door bolts are available, each with distinct features:
- Throw Bolts: A simple, manually operated bolt that is thrown horizontally or vertically. Typically secured with a thumb turn or key.
- Slide Bolts: Consist of a sliding bar that moves horizontally across the door edge. Often used on interior doors.
- Deadbolts: A more secure type of bolt that extends a solid metal bar deep into the door frame. Operated with a key or thumb turn. Single-cylinder deadbolts have a key cylinder on one side, while double-cylinder deadbolts require a key on both sides.
- Surface Bolts: Mounted on the surface of the door and frame. Visible when engaged.
- Hidden Bolts: Designed to be concealed when engaged, offering a more aesthetically pleasing appearance.
- Garage Door Bolts: Specifically designed for garage doors, often featuring a more robust construction.
- Security Bolts: Heavy-duty bolts designed for high-security applications, featuring reinforced materials and tamper-resistant mechanisms.
Door bolts can be categorized based on material, use, and application. These bolts are typically used for securing doors, providing a locking mechanism for both interior and exterior applications. They are commonly made of iron or steel.
The following HS codes are relevant to door bolts, based on the provided reference material:
- 7318152010: Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers (including spring washers) and similar articles, of iron or steel: Threaded articles: Other screws and bolts, whether or not with their nuts or washers: Bolts and bolts and their nuts or washers entered or exported in the same shipment Having shanks or threads with a diameter of less than 6 mm. This code applies to smaller diameter iron or steel bolts used in door applications.
- 7318152020: Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers (including spring washers) and similar articles, of iron or steel: Threaded articles: Other screws and bolts, whether or not with their nuts or washers: Bolts and bolts and their nuts or washers entered or exported in the same shipment Having shanks or threads with a diameter of 6 mm or more: Track bolts. This code applies to larger diameter iron or steel bolts used in door applications.
- 7326908688: Other articles of iron or steel: Other: Other: Other: Other Other. This code is a broad category for other iron or steel articles and may apply if the door bolt doesn't fit neatly into other specific classifications.
- 7326908605: Other articles of iron or steel: Other: Other: Other: Other Rods for electrical grounding (potentially if the bolt is rod-shaped). This code may be applicable if the door bolt is rod-shaped and used for electrical grounding purposes.
- 8301406030: Padlocks and locks (key, combination or electrically operated), of base metal; clasps and frames with clasps, incorporating locks, of base metal; keys and parts of any of the foregoing articles, of base metal: Other locks: Other Door locks, locksets and other locks suitable for use with interior or exterior doors (except garage, overhead or sliding doors). This code applies to door locks and locksets, which may include bolts as part of the assembly.
Important Note: For HS code 7318152010 and 7318152020, the diameter of the bolt's shank or threads is a critical factor in determining the correct classification.
Regarding HS codes 7318152010 and 7318152020, please note that the bolts and nuts or washers must be entered or exported in the same shipment for this classification to be valid. Additionally, for HS codes 7318152010, 7318152020, 7326908688 and 7326908605, the material (steel or aluminum) may affect the applicable tariff rates, with a 25%加征关税 applying to steel and aluminum products.
