Clearance Lee Valley 1/4-20 Quick-Connect Capped Insert Nut

Used for through joints where the nut may be exposed, this nut has a closed end and is knocked into the pre-drilled hole.

The teeth hold the nut in place and prevent it from turning as the bolt is tightened.

The nut is die-cast from a zinc alloy. Pre-drill size will vary from 8.3mm to 8.7mm, depending on material thickness and density.
