Product Description

The Top Burst Screw, often referred to as the top burst expansion screw or ceiling expansion bolt, is a revolutionary fastening solution designed to excel in diverse installation scenarios. Its unique structure and performance set it apart, making it an essential component in many projects. Below is an in-depth exploration of its structure, operating principle, distinct characteristics, versatile usage scenarios, application methods, and important precautions to consider:

Structure: This innovative screw system is primarily composed of a casing, an expansion tube, a screw, a nut, and a gasket. The cylindrical casing features a closed bottom and an open top. Nestled inside is the expansion tube, through which the screw is threaded. The screw's top is flat or cross-shaped, facilitating easy tool engagement, while its bottom boasts a conical design. Nuts and washers are employed to securely fasten objects.

Working Principle: Begin by drilling a hole into the installation base. Insert the top burst screw into this pre-drilled hole and twist the screw using a suitable tool. This action causes the screw to ascend, gradually expanding the cone at its base, which in turn widens the expansion tube. The closed bottom of the casing ensures the expansion is directed outward, tightly adhering to the hole walls. This process generates significant friction and anchoring force, ensuring the object is securely affixed to the base.

• Characteristics

Robust Anchoring Force: Thanks to its specialized structure, the top burst screw achieves a superior contact area with the hole wall upon expansion. This results in anchoring force that surpasses that of conventional expansion screws, making it an ideal choice for suspending heavier items.

Efficient Installation: The process is straightforward, with the simple action of tightening the screw completing the expansion and fixation. This significantly enhances construction efficiency, saving both time and effort.

Aesthetic Concealment: Once installed, the sleeve remains hidden within the hole, providing a clean and polished appearance. This feature is perfect for applications where aesthetics are a priority.

High Stability: The top burst screw maintains a reliable fixing effect even under conditions of high tension and vibration, ensuring a stable and trustworthy connection that stands the test of time.

• Usage scenarios

Decoration and Renovation: Perfect for securing ceiling joists, chandeliers, and large decorative art pieces, safeguarding the integrity and stability of decorative elements.

Home Installation: Ideal for anchoring heavy furniture such as expansive wardrobes and bookcases, ensuring the furniture is safely secured for everyday use.

Engineering Construction: Provides steadfast support and fixation in mechanical and electrical equipment installations, pipeline anchoring, and various engineering endeavors.

• Instructions for use

1. Measurement and Positioning: Use precise measuring tools to accurately mark the drill points at the designated installation location, in accordance with the installation requirements.

2. Drilling: Select a drill bit that matches the specifications of the top burst screw. Drill vertically at the marked point, ensuring the hole depth exceeds the screw's length to allow full insertion.

3. Screw Insertion: Insert the entire top burst screw assembly into the drilled hole, ensuring the sleeve is snugly aligned with the hole wall for optimal installation.

4. Fixing Objects: Position the item to be secured onto the screw, then sequentially place the gasket and nut. Use a wrench or power tool to tighten the nut, prompting the screw's upward motion and expansion tube's deployment to finalize the fixation.

• Precautions

Specification Matching: Select the top burst screw specifications based on the installation object's weight, size, and material to ensure its load-bearing capacity is adequate for the task.

Quality Inspection: Prior to installation, meticulously inspect each component of the top burst screw. If any deformation or damage to the screw or expansion tube is detected, replacement is necessary to maintain effective fixation.

Controlled Force: When tightening the nut, avoid excessive force that could fracture the screw or over-expand the tube, potentially damaging the substrate. Similarly, inadequate force won't achieve a satisfactory fixation.
