Z-Form® Assembly
For joints subjected to high shear loads.
Typical bolted joints require clearance to accommodate machining tolerances and rely solely on clamp load to prevent joint slip. In joints subjected to high shear loads, traditional bolted joint assemblies may not be capable of keeping the clamped components from moving laterally in relation to each other. Dowel pins and locating sleeves are traditionally used to resist these shear loads.
The Z-Form® Assembly consists of a shoulder bolt with a pre-assembled deformable sleeve which, when installed completely eliminates clearance between the bolt and the through hole in the clamped component. This increases resistance to slippage, retains clampload and extends gasket/seal life.
