Small Parts - threaded pin
VEF26 Threaded Pin fits into the ends of the roll bar to connect the tops of the side rails. It is 1/4" x 20 2 1/2" zinc plated steel with an 1/8" hole drilled on one end.
This a 1/4" x 20 x 2 1/2" grade 5 zinc plated steel bolt with the head cut off of the end and an 1/8" hole drilled 1/4" from one end and threads cut 7/8" up the other end.
The threads are treated with a thread lock material and inserted into the end of the roll bar so that it protrudes enough to allow a cotter pin to secure the roll bar to the side rail.
