Reinforced Panel Lockbolts

FRP bolts, or lockbolts for fiberglass reinforced plywood, are two-piece specialty fasteners designed specifically for FRP and metal clad composite panel applications. They install with a consistent pressure; you don't have to worry about over or under tightening, reducing the potential for crushing or crazing FRP panels.

These FRP bolts prevent cracking and pull through of composite materials and are ideal for the assembly of GRP vehicle panels. They feature high shear strength for strong joint integrity and an under head seal. The internally locked stem provides a secure, vibration resistant joint with a smaller shell size available for use against metal surfaces and FRP giving its low profile head and a neat appearance. There are optional encapsulated heads to match surrounding panel colors on these.
