Flat Head Hexagonal Double-Section Bolt

Product introduction

Flat head hexagonal double-section bolts are special fasteners in the field of industrial assembly, with the dual function of "positioning + fastening" as their core advantages. Its structure is divided into two sections: one end is a standard external thread, which is suitable for nuts of corresponding specifications for locking; the other end is a flat bar-shaped body that can be inserted into a preset slot to avoid rotational deviation after installation and greatly improve the stability of the connection. The surface of the product is treated with galvanizing process, which has excellent anti-rust and corrosion resistance, and is suitable for complex working conditions such as humid and outdoor conditions. The model mark engraved on the bolt body facilitates specification differentiation and batch traceability, and meets the needs of industrial mass production and management. The bolt is widely used in scenarios such as mechanical equipment guide rail fixation, steel structure frame splicing, and electrical equipment chassis assembly. It is especially suitable for assembly processes that require precise positioning. It not only simplifies the installation process, but also maintains long-term connection reliability. It is an industrial basic accessory that takes into account practicality and adaptability.

 

Product features

1. Integration of structure and function

It adopts a "flat head + thread" double-section design: the flat head section can be embedded in the corresponding slot to achieve precise anti-rotation positioning; the thread section is tightened with the nut to meet the dual requirements of "positioning + locking" without the need for additional positioning parts.

 

2. Strong environmental adaptability

The surface is galvanized and has good anti-rust and corrosion resistance. It can be stably used in various working conditions such as outdoor, humid, and industrial workshops to extend the service life of the bolts.

 

3. Efficient and convenient installation

The hexagonal/flat structure of the flat head matches the slot well. No additional tools are required to fix the bolts during installation. One person can complete the assembly, which greatly improves the process efficiency in mass production.

 

4. Clear and easy to manage labels

The main body is engraved with identification such as model number and batch to facilitate specification differentiation, inventory management and quality traceability in industrial production, and is suitable for large-scale supply chain systems.

 

5. Excellent connection stability

The fitting structure of the flat head and the slot can effectively resist the influence of external forces such as vibration and impact, prevent bolts from loosening, and ensure connection reliability in long-term use.

 

Product application

1. Mechanical equipment field

Suitable for guide rail installation of various machine tools and automation equipment: the flat head is embedded in the guide rail groove to achieve precise positioning, and the threaded end is locked with a nut to prevent the guide rail from shifting during operation. Fixing of equipment transmission components: such as the connection of gear boxes and conveyor belt brackets, using the anti-rotation characteristics of the flat head to ensure transmission stability.

 

2. Steel structure and frame engineering

Light steel structural frame splicing: used for positioning and fastening angle steel, channel steel and other profiles, replacing traditional welding or ordinary bolts, simplifying the on-site assembly process. Outdoor facility frames (such as photovoltaic brackets, guardrails): Galvanized anti-rust properties are suitable for outdoor environments, and the flat head design improves the wind load resistance of frame connections.

 

3. Electrical and chassis equipment

Chassis assembly of distribution boxes and control cabinets: The flat head is inserted into the reserved slot of the chassis to avoid bolt rotation and ensure precise closing of the door and panel. Internal bracket fixation in the electrical cabinet: suitable for dense wiring scenarios, taking into account installation efficiency and connection reliability.

 

4. Rail transit and vehicle accessories

Fixing of interior frames and components of rail transit equipment: The anti-rotation design of the flat head is adapted to vibration conditions and ensures connection stability during long-term operation.

 

FAQ

Q: Can the size of the flat head of the flat head hexagonal double section bolt be customized?

A: Customization is supported. The size parameters of the flat head can be adjusted according to the specifications (width, thickness) of the equipment slot. Slot drawings or specific size requirements must be provided in advance.

 

Q: Does the flat head need to be lubricated during installation?

A: No additional application is required. The flat head and the slot are designed for clearance fit and can be directly embedded. If the slot accuracy is high, a small amount of industrial butter can be applied to assist assembly, but avoid oil contamination from affecting the thread locking effect.

 

Q: What does the "1345" logo on the bolt mean? Can I customize the logo content?

A: "1345" is usually the model or batch number; custom logos (such as corporate logos, specification codes) are supported, and the size and clarity requirements for logo engraving must be met. The customization minimum order quantity needs to be negotiated with the supplier.
