Slotted Head Step Break-Stem Blind Rivet
Products Description
Traditional blind rivets are prone to breakage during the riveting process, which can affect the locking effect and the appearance of the installation. The Slotted Head Step Break-Stem Blind Rivet structure, however, optimizes the change in the rivet's cross-section, making the breakage point more stable and controllable.
Its advantages include:
Uniform breakage position, neat appearance
Reduced residual burrs and breakage issues
Improved compatibility with automated assembly
Reduced manual rework rate
Enhanced overall connection stability
This stability is particularly critical for new energy vehicle battery packs, energy storage boxes, and precision sheet metal structures.
Technical Features: Combination of Break-Stem Technology and Blind Spot Installation
Predictable Breaking Load
The break point of the mandrel is precision-machined to ensure a clean and decisive break when the preset tensile force is reached, leaving a flat and tightly embedded head that forms a secondary mechanical lock.
Ease of Single-Sided Installation
Designed specifically for enclosed structures (such as pipe inner walls and chassis cavities), Flat Head Step Rivet allows for high-quality riveting without the need for rear-end support.
High Shear and Tensile Strength
The stepped section increases the shear cross-sectional area, resulting in significantly improved performance compared to standard rivets of the same specification when subjected to lateral loads.
Application Advantages: A Powerful Tool for Overcoming Assembly Pain Points Across Multiple Industries
Automotive Components and New Energy Battery Packs
In the sealing and fixing of battery casings, Step Flat Head Rivets not only firmly lock thin aluminum plates and composite insulation boards, but their large diameter section can also effectively seal excessively large mounting holes. Combined with sealing gaskets, this significantly improves the IP68 waterproof and dustproof rating of the battery pack.
HVAC and Ventilation Ducts
Flange connections in ventilation ducts often have significant hole misalignment. Slotted Head Step Rivets can directly pass through misaligned holes to achieve a tight fit, and the slotted head design facilitates pre-positioning within narrow ducts, greatly improving on-site construction efficiency.
Metal Curtain Walls and Precast Building Components
In the dry-hanging system of high-rise building facade components, Slotted Flat Head Step Rivets can compensate for hole misalignment caused by keel welding. Simultaneously, their full blind-side expansion provides strong shear resistance against high-altitude wind loads.
Detailed Showcase: Micron-Level Quality Control Determines Assembly Yield
| Flat, burr-free break | Observing the head after riveting, the break point of the core rod must be flush with or slightly concave with the top surface of the Flat Head Step Blind Rivet head. Our process ensures that no sharp, outward-curling burrs are produced after breakage. In automotive interiors or electronic devices, protruding burrs can cut through the wiring harness insulation layer; a flat break point is the baseline for electrical safety. |
| Fully Fitted Locking Ring Recess | Observing from the side of the rivet head, and even touching it, one can clearly feel a slightly raised metal ring inside the head. This is proof that the core rod break is perfectly embedded in the locking ring recess, meaning that the Flat Head Step Break-Stem Rivet has formed an irreversible mechanical lock, capable of withstanding hundreds of thousands of high-frequency vibrations. |
| Crack-free Expansion Texture on the Blind Side | Observing the expansion area on the blind side through X-ray or destructive cutting, the metal fibers of a high-quality Flat Head Step Structural Rivet should exhibit a smooth stretching state, with a smooth surface and no micro-cracks visible to the naked eye. Any tiny longitudinal crack can propagate rapidly under dynamic loads, leading to rivet failure. |
