Product Description

Introducing the Top Burst Screw, also recognized as the top burst expansion screw or ceiling expansion bolt, a specialized expansion screw that excels in diverse installation scenarios thanks to its innovative structure and exceptional performance. Dive into a comprehensive exploration covering its structure, working principle, distinctive features, varied applications, step-by-step usage guide, and important precautions for optimal use:

Structure: This screw is ingeniously designed with a casing, expansion tube, screw, nut, and gasket. The cylindrical casing features a closed bottom and an open top, housing the expansion tube within. The screw pierces through it, boasting a flat or cross-shaped head for convenient tool use, and a conical base structure. Nuts and washers ensure secure fastening of objects.

Working Principle: Begin by drilling a hole in your chosen installation base, then insert the top burst screw. Engage a tool to twist the screw, prompting upward movement of the screw. The conical end expands the tube outward due to the casing's closed bottom, exerting substantial force against the hole wall. This generates remarkable friction and anchoring strength, steadfastly securing your object to the base.

• Characteristics

Robust anchoring power: Its unique structure allows for an expanded contact area with the hole wall, delivering superior anchoring force compared to standard expansion screws, making it ideal for suspending heavier items.

Swift installation: The process is straightforward. Tightening the screw achieves expansion fixation, markedly boosting construction efficiency and minimizing installation time.

Excellent concealment: Post-installation, the sleeve remains in the hole, ensuring a neat appearance. This makes it perfect for scenarios where aesthetics are paramount.

Unwavering stability: Even under substantial tension and vibration, it maintains a reliable fixing effect, ensuring the connection remains stable and trustworthy.

• Usage Scenarios

Decoration and Renovation: Ideal for installing ceiling joists, chandeliers, and large decorative art pieces, guaranteeing the safety and stability of all decorative fixtures.

Home Installation: Perfect for securing heavy furniture such as large wardrobes and bookcases, ensuring furniture remains safely in place.

Engineering Construction: Offers dependable support and fixation for equipment and components in mechanical, electrical installations, pipeline stabilization, and various engineering endeavors.

• Instructions for Use

1. Measurement and Positioning: Use precise measuring tools to accurately mark drilling points as per installation specifications, ensuring optimal placement.

2. Drilling: Choose a drill bit matching the top burst screw's specifications, drill vertically at the marked site, ensuring the hole's depth slightly exceeds the screw's length for complete insertion.

3. Screw Insertion: Insert the entire top burst screw into the drilled hole, ensuring the sleeve is firmly secured against the hole wall for optimal stability.

4. Object Fixation: Position the object to be secured over the screw, layer the gasket and nut in sequence, then use a wrench or power tool to tighten the nut. As the screw ascends, the expansion tube extends to achieve firm fixation.

• Precautions

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

Quality Inspection: Prior to installation, meticulously inspect all top burst screw components. Replace any deformed or damaged screws or expansion tubes promptly to maintain optimal fixing efficacy.

Controlled Force: Avoid over-tightening the nut to prevent screw breakage or excessive tube expansion, which could damage the substrate. Conversely, insufficient force will fail to secure effective fixation.
