ABSTRACT:
A trailer door fastener includes a T-nut and a bolt. The T-nut includes a large washer face with a hollow cylinder extending coaxially from and perpendicular to the washer face. The hollow cylinder contains internal threads running the entire length of the hollow cylinder. The bolt includes a large head with a shank extending coaxially from and perpendicular to the head. On the shank adjacent the head is a knurled portion with grooves running parallel to the axis of the shank. The remainder of the shank has external threads running from the end of the knurled portion opposite the head to the end of the shank opposite the head. The bolt is inserted through aligned holes in the hinge plate and the door panel from the outside of the trailer such that the knurled portion traverses the interface between the hinge plate and door panel. This provides a greater surface area on the bolt to withstand shear forces at the interface. The T-nut is inserted into the hole in the door panel from the inside and screwed onto the bolt. The length of the knurled portion of the bolt is custom fitted to the thickness of the door panel and hinge plate to ensure that the knurled portion traverses the interface and that the internal threads of the T-nut fully engage the external threads of the bolt.
