# Split Reaction Nut Usage

The split reaction nut is a completely separate component and is assembled onto the bolt after the tensioner has been fitted.

1. Position the split reaction nut over the bolt.

2. Press the nut release button to snap the split reaction nut into the ‘open’ position. The two halves of the split reaction nut will spring apart.

3. Position the split reaction nut over the stud protrusion.

4. Squeeze the two halves of the split nut together, after placing them on the top face of the tensioning tool. A ‘click’ can be heard when the two halves click into their closed position.

5. Using a Tommy Bar slotted into the a slot of the split reaction nut, rotate the reaction nut downwards until it engages fully into the tensioner's coned seat.

6. Before tensioning begins, ensure at least three threads is protruding above the split reaction nut when the split reaction nut is fully engaged into the coned seat in the top face of the tensioning tool.

   A: At least three threads should protrude from the top of the split reaction nut.

Never load a split reaction nut that has not ‘clicked’ into its fully closed position.

Never load a split reaction nut that has not got full thread engagement throughout its full length.

Repeat direct reverse assembly procedure when disassembling.
