Lockbolt 02621-07008 Steel C6LB-R8-8G Rivets 6.4*10mm

Description

Product Introduction
The 02621-07008 model C6LB-R8-8G 6.4 * 10mm steel lock bolt (ring groove rivet) produced by VANGUARD INDUSTRIAL is a high-strength anti loosening fastener designed specifically for heavy-duty conditions
Core parameters: nominal diameter 6.4mm, compatible riveting total thickness up to 10mm, complete set including semi-circular steel nail rod and matching steel lock ring, made of high-quality carbon steel, with tensile strength up to 7840N and shear strength up to 6760N, far exceeding ordinary bolts and conventional rivets in mechanical performance.
Performance characteristics: It belongs to high reliability permanent locking fasteners. After riveting, the locking ring will be squeezed and embedded into the annular groove of the nail rod, forming a rigid connection without gaps. It has strong anti vibration and anti loosening ability, good riveting consistency, and will not have the problem of loosening and failure of ordinary threaded connections after long-term use.
Applicable scenarios: Widely used in fastening scenarios such as rail transit vehicles, heavy trucks, mining engineering machinery, steel structure engineering, wind power equipment, etc. that require long-term high load and high-frequency vibration, it is the preferred solution to replace ordinary bolts in the industrial heavy-duty field.
🛠️ Usage
Preparation in advance
Drill a matching through-hole with a diameter of 6.5-6.6mm on the workpiece to be connected based on the nominal diameter of the rivet 6.4mm. Clean the burrs and debris in the hole, confirm that the workpiece is completely fitted without gaps, and then fix it in place.
Pre installed alignment
Insert the rivet rod into the through-hole from one side of the workpiece, and fit the matching steel locking ring onto the annular groove section where the rivet rod extends out of the workpiece, ensuring that the locking ring is completely attached to the surface of the workpiece and that the rivet rod is perpendicular to the end face of the workpiece.
Riveting operation
Select a specialized pneumatic/hydraulic ring groove rivet gun that is compatible with the 6.4mm specification, inject a small amount of lubricating oil into the tool in advance and adjust it to the rated working pressure. Align the gun head with the tail clamping section of the nail rod and clamp it tightly. After the gun head is tightly locked to the end face of the locking ring, start the tool. Under tension, the locking ring will undergo plastic deformation and be tightly embedded in the annular groove of the nail rod. When the tension reaches the set threshold, the nail rod will break neatly at the preset neck position, completing high-strength locking in one go.
Completion inspection
After riveting is completed, visually inspect that the locking ring is fully inserted into the nail groove without any looseness or displacement. Confirm that the riveting end face is flat and free of protrusions or deformations, and the entire connection operation can be completed. It can be directly put into heavy-duty use without additional reinforcement.
