CALIBRATED PRELOAD ASSEMBLY

ABOUT

Calibrated Preloaded Assemblies (CPA) are designed to replace conventional high strength friction grip bolts and rivets, which can be used on almost any steel construction connection.

 

The grade 10.9 high tensile strength bolt is identified by the round head and unique shape spline able to undergo significant deformation before rupture.

A lightweight electric shear wrench can easily install the bolt with correct tension and remove the spline at the same time, reducing the time it takes to install and the risk of human error by visual inspection. 

 

CPA bolting assemblies cover a range of sizes from M12 to M36. Manufactured in accordance with BS EN 14399-10:2018 and 

‘CE’ Marked in accordance with 

BS EN 14399-1:2015.

All CPA assemblies are hot dipped galvanized to BS EN ISO 10684:2004.
