BoxJoint Nuts

Bolts

The BoxJoint nuts are the elements that the bolts are screwed to in order to secure the box pair. The Double nut is used when two plates are in direct contact where screws are coming in from both sides. The Anchor nut is found in Squeeze joints or when long bolts are used to reduce the number of bolts. The second case requires Sleeve bolts instead of Double nuts when the plates are in direct contact.
