Coil Bolt
Coil bolts are designed with fast-threading, self-cleaning threads.
The threads are contoured to mate with the helix coils of coil ties
and coil loops. Coil bolts may be furnished with standard formed
head or made from coil rod with heavy hex nut welded on.
Available in 3/4", 1", 1-1/4" and 1-1/2" diameter.
