Product Description

Top burst screw, often termed as top burst expansion screw or ceiling expansion bolt, is a specialized expansion screw that is invaluable in diverse installation setups due to its distinctive design and exceptional performance. Delve into this detailed overview covering its structure, operational principle, unique characteristics, ideal usage scenarios, step-by-step usage methods, and critical precautions needed when using this robust solution:

Structure: Predominantly composed of a cylindrical casing with a closed bottom and an open top, an expansion tube, a screw, a nut, and a washer. The internal expansion tube is penetrated by the screw. The screw's top is fashioned flat or cross-shaped, simplifying tool use for twisting, while its bottom is conically structured. Nuts and washers play a pivotal role in securing the desired objects, ensuring a seamless and sturdy installation.

Working principle: Begin by drilling a precise hole in the installation base, insert the top burst screw into this hole, and use a tool to twist the screw. As the screw ascends, the cone at the base expands the tube. The casing's closed bottom ensures outward tube expansion, tightly compressing against the hole wall, creating enhanced friction and anchoring force, securely fastening the object firmly onto the base.

• Characteristics

Strong anchoring force: Its innovative structure results in a larger contact interface with the hole wall post-expansion, offering superior anchoring strength over ordinary screws, perfect for securing heavier items.

Efficient installation: Its straightforward operation means that simply tightening the screw accomplishes secure expansion, markedly boosting overall construction efficiency.

Good concealment: Post-installation, the sleeve remains discreetly within the hole, presenting a clean aesthetic suitable for installations where appearance is key.

High stability: It consistently ensures a firm fixing effect, even under high tension and vibration, with stable and reliable connections at all times.

• Usage scenarios

Decoration and renovation: Perfect for installing ceiling joists, chandeliers, and large decorative artworks, ensuring the safety and steadfastness of these decorative elements.

Home installation: Ideal for securing heavy furniture pieces like large wardrobes and bookcases, providing peace of mind and ensuring the safety of household items.

Engineering construction: Offers robust support and secure fixation for machinery and components in mechanical and electrical setups, pipeline installations, and varied engineering projects.

• Instructions for use

1. Measurement and positioning: Based on installation needs, utilize measuring tools to mark drilling points with pinpoint accuracy at the intended installation site.

2. Drilling: Select a drill bit tailored to the top burst screw dimensions, drill vertically at the marked point, ensuring the hole depth exceeds the screw length slightly, facilitating a complete insertion.

3. Screw insertion: Insert the entire top burst screw into the prepared hole, ensuring the sleeve snugly aligns with the hole wall, setting the stage for a secure fit.

4. Fixing objects: Position the object to be secured onto the screw, sequentially place the gasket and nut, then use a wrench or power tool to tighten the nut. As the screw advances, the expansion tube widens, finalizing the fixation efficiently.

• Precautions

Specification matching: Choose the top burst screw specifications that align with the weight, size, and material of the installation object, ensuring it meets the necessary load-bearing capacity.

Quality inspection: Thoroughly inspect all top burst screw components pre-installation. Any deformed or damaged screws or tubes should be promptly replaced to maintain optimal fixing performance.

Control force: When tightening the nut, apply controlled force to prevent screw breakage or excessive tube expansion, which could damage the substrate. Avoid insufficient force, which would compromise the secure fixing effect.
