73 TA 6-6 (4.8 Ø x 16L) Sealed Dome Alum Steel Rivet Grips 7.5-11.5mm

Description

Product Introduction
This VANGUARD INDUSTRIAL 73 TA 6-6 closed round head aluminum steel pop rivet is a high-performance sealed single-sided rivet fastener:
Core parameters: The nominal diameter of the rivet is 4.8mm, the length of the rivet body is 16mm, and the total thickness range of the compatible rivet workpiece is 7.5-11.5mm. The rivet body is made of aluminum alloy material and the nail core is made of steel material, balancing lightweight and high-strength connection performance.
Structural advantages: It belongs to the closed type waterproof core pulling rivet. After riveting, the head of the core will be completely enclosed inside the rivet body, forming a closed cavity, with excellent waterproof and leak proof capabilities. At the same time, it has high shear resistance, vibration resistance, and high pressure resistance. After riveting, the core will not accidentally fall off, and the connection reliability is much higher than that of ordinary open core pulling rivets.
Applicable scenarios: No double-sided operation is required, riveting operations can be completed from only one side of the workpiece. It is widely used in sealing parts of automobile bodies, ship cabins, electrical equipment shells, outdoor hardware components, HVAC pipeline flanges and other scenarios that require sealing performance and connection strength. It is especially suitable for closed structure riveting operations that are inconvenient to operate from the back of the workpiece.
🛠️ Usage
preliminary preparation
Drill a fitting through-hole with a diameter of approximately 4.9mm on the workpiece to be riveted based on the nominal diameter of the rivet of 4.8mm. Clean the burrs and debris in the hole, tightly fit and fix the workpiece to be connected, eliminate all gaps between the workpieces, and ensure that the total stack thickness falls within the fitting range of 7.5-11.5mm.
Clamping and debugging
Choose a manual, electric, or pneumatic riveting gun that is compatible with 4.8mm rivets, replace the corresponding nozzle size, fully insert the rivet core into the nozzle of the riveting gun, and then insert the rivet body into the pre drilled through-hole of the workpiece, keeping the rivet perpendicular to the workpiece surface.
Riveting operation
Start the riveting gun to smoothly pull the nail core, and the rivet body gradually expands and adheres to the wall of the workpiece hole under tension, forming a sealed upsetting structure on the back of the workpiece; When the tension reaches the set threshold, the nail core will break neatly at the preset neck position, and the closed rivet body cavity will be fully formed, forming a firm and sealed reliable connection between the workpieces.
Closing inspection
After riveting, check whether the rivet head is completely attached to the surface of the workpiece, confirm that the back of the rivet head is fully formed without looseness, and verify whether the sealing performance meets the standard through water testing; When storing rivets for a long time, moisture-proof protection should be taken to avoid rusting of the aluminum alloy rivet body and steel nail core, which may affect the riveting performance.
