Description
The hammer drive blind rivet was specially designed for attachment of hard materials to solid wood and similar materials. As soon as the drive pin in the hammer drive blind rivet is struck, the end of the rivet splits into four sections that hold the materials together, while the borehole diameter is 0.5 mm greater than that of the rivet. Ideal for fixing profiles, insulation, etc, on construction materials. The rivets are set with a hammer or striking mechanism.
This rivet is formed in one piece and consists of a body having a helical thread, performing a deformation in the support where it is introduced. The visible round head secures relatively thin parts in all support.
U-drive rivets (also known as hammer drive screws or ) are unslotted round head self tapping rivets often used for attaching nameplates in castings and for sealing drain holes in corrosion proofing tubular structures.
They possess multiple start threads with large helical angles and an unthreaded pilot point.
Similar to nails they are driven into mating parts with a mallet or hammer for a quick and permanent assembly. No tapped threads are required in the mating part.
However, the u-drive screw must be of harder material than the
mating part and a undersized pre-drilled pilot hole is required.
The assembly can be done in a blind hole.
Drilling support and drilling piece to be fixed. The assembly is done manually with traditional tools (hammer, mallet or small hand press).
Used a lot for name plate of label fixing on metal bodies. That is why they are also known as name plate rivets.
