Fastener System for Panel Joints

Product Specifications

Technical details and manufacturing context for Fastener System

Definition

The fastener system is a critical component within panel joint systems, responsible for creating secure, reliable, and often adjustable connections between adjacent panels. It ensures structural integrity, alignment, and load transfer while potentially allowing for thermal expansion, contraction, or modular assembly/disassembly. Its design directly impacts the joint's strength, durability, and ease of installation. The system typically employs mechanical interlocking, clamping force, or a combination thereof. Common mechanisms include bolts/screws applying tension through threaded engagement, clips or latches providing snap-fit or spring-loaded retention, or specialized interlocking profiles that engage when panels are brought together. The principle relies on converting applied force (e.g., torque on a bolt) into clamping pressure or positive mechanical lock to resist shear, tension, and separation forces between panels. Materials on file include stainless steel, carbon steel, and aluminum alloy. Reference parameters include nominal size range M6–M24 (ISO 68-1), tensile strength 800–1200 MPa (ISO 898-1), yield strength 640–1080 MPa (ISO 898-1), hardness 22–38 HRC (ISO 898-1), operating temperature -40–150°C (ISO 3506-1), corrosion resistance ≥500 h salt spray (ISO 9227), thread tolerance 6g–6H (ISO 965-1), surface finish Ra 0.8–1.6 μm (ISO 1302), preload scatter ±15% (ISO 16047), and weight per 100 pcs 0.5–5.0 kg. These values are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier before procurement or use.

Frequently Asked Questions

What is the typical operating temperature range for this fastener system?

According to the reference data, the operating temperature range is -40°C to 150°C, based on ISO 3506-1. Above 150°C, strength may degrade. Always verify the specific model's rating with the manufacturer.

What materials are available for this fastener system?

The materials on file include stainless steel, carbon steel, and aluminum alloy. The choice depends on the application requirements such as corrosion resistance, strength, and weight. Confirm material suitability with the supplier.

How does the fastener system achieve a secure connection?

It uses mechanical interlocking, clamping force, or a combination. For example, bolts apply tension via threads, clips provide snap-fit retention, or interlocking profiles engage when panels are brought together. The applied force is converted into clamping pressure to resist separation.

What standards are referenced for the fastener system's parameters?

Reference standards include ISO 68-1 for thread sizes, ISO 898-1 for mechanical properties, ISO 3506-1 for temperature, ISO 9227 for corrosion resistance, ISO 965-1 for thread tolerance, ISO 1302 for surface finish, and ISO 16047 for preload scatter. These are for verification; actual compliance must be confirmed with the manufacturer.
