Xiaoguo® China factory supports your procurement of this fastener to buy in bulk. The Construction grade Snap head rivets is a type of metal fastener with a head resembling a small round button and a shaft like a nail. Its head is a smooth hemispherical shape, which looks very nice when exposed; during installation, the shaft is inserted through the holes of two parts, and then a tool is used to flatten or thicken the tail of the shaft to form a plug. The two plates are then firmly riveted together.
Once the Construction grade Snap head rivets is installed, it cannot be removed. It is more reliable and less prone to vibration than screws. It is commonly used in the rotating shafts of scissors pliers, iron boxes, car brake pads, copper nails on jeans, etc. The materials include iron (galvanized for rust prevention), copper, stainless steel, aluminum, etc. The choice of material can be made according to actual usage.
Construction grade Snap head rivets have more installation advantages in thin plate connections compared to screws and welding.
Scene: The assembly of the shells of distribution boxes, control cabinets and ventilation ducts
The thin steel plate cannot achieve sufficient thread depth when using a drill bit. Self-tapping screws are prone to slipping. For rivets, only a pre-drilled hole or pre-screwed hole is needed. After insertion, a pull with a riveting gun completes the connection point in just a few seconds.
If a bolt connection is chosen, a nut needs to be provided on the other side. However, if the internal space of the box is narrow or there are already installed components, it is difficult to reach in and tighten the bolt. The operation is quite challenging. The Construction grade Snap head rivets enters from the outside and is tightened from the same side using a riveting gun. No operation is required inside the box.
Welding will burn off the powder coating or galvanizing layer on the surface of the sheet, and after welding, it is necessary to sand and repaint. The Construction grade Snap head rivets installation has no high temperature or sparks, and does not damage the surface coating. The flat round head is smooth and beautiful, and there are no protruding bolt heads on the box surface, which meets the appearance requirements of electrical products.
Blade pre-drilling → Workers place rivets → Pneumatic riveting gun rivets, with a cycle time of 20-30 rivets per minute. This is much faster than welding or bolt connections, making it suitable for large-scale sheet metal processing.
