Bucket screw, also referred to as bucket bolt or dustpan screw, is a distinctive fastener characterized by its unique head shape. Let's delve into its detailed description:
1, Basic structure
The bucket screw is ingeniously crafted with two integral components: the head and the screw.
1. Head: Fashioned in the shape of a hopper or hexagonal cone, this is the standout feature of bucket screws. Its design ensures superior locking capability and enhanced load-bearing strength during installation.
2. Screw: It features a cylindrical body adorned with threads, designed to dovetail seamlessly with threaded holes on the component to establish a robust connection.
2, Performance characteristics
1. High strength: Crafted from high-strength steel, bucket screws withstand significant tensile and shear forces, making them ideal for heavy-duty applications.
2. Wear resistance and corrosion resistance: With advanced surface treatments like galvanizing, spraying, or hot baking paint, bucket screws boast superior wear and corrosion resistance, adapting to outdoor environments or challenging conditions.
3. Easy installation and disassembly: While installation and disassembly necessitate professional tools and techniques, their special head shape ensures an unwavering locking effect once installed, resisting loosening.
3, Application scenarios
Thanks to its remarkable structure and attributes, bucket screws find wide usage across these domains:
1. Mechanical equipment: Utilized in the liners, hoppers, and belt connections of heavy machinery like ball mills, crushers, elevators, and conveyors, they secure and connect vital components.
2. Construction engineering: Bucket screws are prevalent in connecting steel structural components in construction projects, delivering formidable fastening strength.
3. Other industrial fields: Industries such as mining machinery, oil well operations, and drilling rigs demand high-strength and reliable fasteners, where bucket screws excel in meeting these stringent requirements.
4, Selection and Installation
Critical points to consider when selecting and installing bucket screws include:
1. Choose appropriate specifications and models: Base your choice on the material, thickness, and connection requirements of the parts. Ensure the head shape, screw diameter, length, and other parameters align with the component.
2. Use professional tools: Deployment and removal require specialized tools, such as wrenches, screwdrivers, or rivet guns. Steer clear of using improper tools to avoid damage or incorrect installation.
3. Pay attention to installation sequence and force: Tighten bucket screws in the correct order and with the proper force. Avoid overtightening to prevent breakage or component damage.
5, Maintenance and upkeep
To prolong the service life of bucket screws, implement regular maintenance and care:
1. Check the fastening status: Routinely verify the bucket screws' fastening state to ensure there's no loosening or detachment. Address any looseness promptly by tightening.
2. Clean surface dirt: Regular cleaning of dirt and corrosive substances from the bucket screw surfaces ensures they remain clean and dry.
3. Replace damaged screws: Promptly replace any damaged or worn bucket screws with new ones to ensure reliable and safe connections.
