SELF-PIERCE
RIVETING
STRONG, RELIABLE JOINTS,
NO PRE-DRILLED HOLES.
Self-Pierce Riveting (SPR) is a specialised mechanical joining process in which a semi-tubular rivet is driven through multiple layers of material to create a secure, permanent joint.
As the rivet passes through the material, it expands and flares within a specially designed die, mechanically interlocking the material layers without the need for pre-drilled holes. The result is a strong, reliable joint that is well suited to a wide range of industrial applications.
NO PRE-DRILLED
HOLES
SPR pierces and joins the material in a single operation, eliminating the need for pre-drilled holes.
STRONG
MECHANICAL JOINT
The rivet flares beneath the material layers to create a secure mechanical interlock.
