†Prepunched or predrilled holes are recommended for bottom-up installation configurations.
*NOTE: Values shown are for steel materials only. Aluminum applications must be indivdually tested to determine performance parameters. Size
M10 requires application testing whether they are used in steel or aluminum applications.
Underhead shape and dimensions controlled by manufacturer to meet performance requirements.
Performance data shown are typical results obtained under laboratory conditions. It is recommended that each application be tested individually
for precise values. For performance in materials other than steel, individual testing is a requirement. This data is not to be considered a
specification.
Contact an Acument Global Technologies applications engineer for assistance.
This cross-section of an actual
application demonstrates how the
application material cold flows into the
retaining groove of the TSPN nut.
