Multi Grip Al/St 4.8*25*16

Description

Product Introduction
This 4.8 × 25 × 16 large brim multi grip aluminum steel pop core rivet produced by VANGUARD INDUSTRIAL is a highly adaptable wide riveting universal fastener:
Core parameters: The nominal diameter of the rivet is 4.8mm, paired with a large diameter umbrella shaped brim. The rivet body is made of lightweight anti rust aluminum alloy material, and the nail core is made of high-strength steel. The overall color is native metallic silver without additional coating.
Structural advantages: As a multi grip wide riveting range design, its effective riveting thickness coverage range is much larger than that of ordinary rivets of the same specification, which can adapt to workpieces with different stacking thicknesses and significantly reduce stocking costs; The oversized brim has a larger contact support area compared to conventional rivets, which can disperse riveting pressure, prevent soft and brittle workpiece surfaces from being fractured, and has better tensile and shear resistance.
Applicable scenarios: Riveting operations can be completed from only one side of the workpiece, widely used in sheet metal assembly, outdoor facility fastening, soft sheet metal splicing, chassis and cabinet assembly and other scenarios. It is particularly suitable for installation needs with small tolerances in workpiece thickness and the need to protect vulnerable workpiece surfaces. It is a cost-effective fastening solution that balances universality and high reliability.
🛠️ Usage
preliminary preparation
Drill a fitting through-hole with a diameter of approximately 4.9-5.0mm on the workpiece to be riveted based on the nominal diameter of the rivet of 4.8mm. Clean the burrs and residual debris in the hole, tightly fit and fix the workpiece to be connected, eliminate excess gaps between the workpieces, and confirm that the total stack thickness of the workpiece is within the effective riveting range of this rivet.
Clamping and debugging
Choose a riveting gun that is compatible with 4.8mm rivets, replace the corresponding nozzle size, fully insert the steel rivet core of the rivet into the nozzle of the riveting gun, and then pass the aluminum rivet body of the rivet through the through hole of the workpiece, keeping the rivet perpendicular to the workpiece surface and ensuring that the large cap edge is flat and fits the workpiece surface.
Riveting operation
Start the rivet gun smoothly to pull the nail core, and the aluminum rivet body gradually expands under tension, forming a full locking head on the back of the workpiece; When the tension reaches the set threshold, the steel nail core will break neatly at the preset neck position, completing the riveting operation.
Closing inspection
After riveting is completed, check whether the large cap edge is flat, without deformation, and fully adheres to the surface of the workpiece. Confirm that the back upsetting head is fully formed without looseness, and gently shake the workpiece to confirm that the connection is firm without displacement; When storing rivets for a long time, take moisture-proof measures to avoid rusting and affecting the riveting performance.
