Info
PIAS®-KP self-piercing nuts are designed to meet high strength thread requirements and higher torque demands of
the automotive industry (for example), with thread sizes ranging from M5 to M10 and are available in strength
classes 8 and 10 material. They can be specified for panels ranging from 0.6mm to 2.0mm. The Pias® installation
tooling system is required to install Pias® nuts.
Available in metric thread sizes in strength class 8 and 10 steel, they can be supplied as unplated or with a range of
electro plated zinc finishes including zinc/clear, zinc/nickel and zinc/thick film passivated.
Benefits of Pias® KP Nuts include:
•
Self piercing so no need to pre-punch the hole, meaning one less process is required and there is no potential
for misalignment between hole and nut
•
Reliable, flexible installation process
•
High torque values
•
No surface distortion
•
Various feeding options available
•
Can be specified with a self-locking thread
