Through Bolts

How to install a through bolt

To install a Through Bolt, drill the required size hole and blow out any dust. This can be done with a blow out pump or similar piece of equipment. Screw the nut into position just below the chamfered head and tap the anchor into the hole using a hammer. Tighten it to the recommended torque size.

A quick tip - if you don’t have a torque wrench to hand we suggest tightening the nut finger tight, then make a small mark on the top of the nut, noting the position of the mark for a guide.  Tighten the nut a further 3 to 4 full turns using a wrench to ensure that sufficient torque is applied.

It always advisable to check the nut a short while after installation, as it may creep slightly loose and require re-tightening.
