Hex Base and Locking Flange Pallet Nuts are designed for wood pallet assembly.

Hex Base Pallet Nuts allow the user to drive or hold the nut with a hex key or bit to tighten assembly. 

Locking Flange Pallet Nuts grip the wood to prevent turning when tightening bolt. Unique low profile nut with hex drive can be tightened instead of the bolt to make it ideal for carriage bolt applications.

Trailer Nuts have a dished flange and more shear strength than a conventional T-Nut.  Used by trailer manufacturers for metal and FRP body attachments.
