Products Description
This special type of Slotted Head Step Break-Stem Blind Rivet is essentially a precision fastening component with multi-level load distribution. It not only performs basic blind-punch connections but also, through its unique "step" design, achieves secondary compensation and reinforcement of the hole diameter during the riveting process.
Its core feature lies in utilizing controlled failure technology based on broken rods to achieve precise control of the pressure at the connection interface. The addition of the slotted groove serves not only as auxiliary positioning during installation but also as a reference for unloading under specific maintenance conditions.
Design Advantages: Stepped Force Distribution and Fluid Forming
Unique Step Mandrel
Unlike ordinary straight rivets, our stepped design creates a physical limit at the moment of riveting. This structure ensures that the Flat Head Step Rivet body preferentially fills the gap at the bottom when expanding, resulting in extremely high fastening density in ultra-thin or ultra-thick sheet metal connections and effectively preventing wobbling caused by hole diameter tolerances.
Precision Milled Slotted Head
The slot depth of the Step Flat Head Rivet head is rigorously calculated mechanically. While ensuring the integrity of the head structure, it reduces the risk of slippage of installation tools and provides physical feature points for subsequent visual inspection or automated alignment.
Consistent Breakage Control
Through micron-level machining of the pre-set fracture groove in the Slotted Head Step Rivet core, precise breakage is ensured the instant the design tensile force is reached. This guarantees completely consistent residual tensile force at every riveting point, a prerequisite for uniform stress distribution in large structural components.
Manufacturing Advantages: A Leap from Cold Heading to Micro-Precision
Multi-Station Cold Heading
Our stepped shapes are formed in one step through cold extrusion, rather than machining. This process preserves the internal fiber flow lines of the metal, increasing the Flat Head Step Blind Rivet's fatigue strength by over 40%.
Automatic Mirror Polishing System
Ensures smooth, burr-free edges on the slotted head. In consumer or medical-grade products with extremely high aesthetic requirements, this refined feel significantly enhances the final value.
Digital Hardness Monitoring
Batch-by-batch monitoring of the heat treatment hardness curves for broken cores ensures a dynamic balance between brittleness and toughness at the fracture point for Slotted Flat Head Step Rivet.
