Using a safety wire or lock wires with safety wire bolts is common in the oil & gas industry, as well in aircraft and racing, as an extra precaution to keep critical bolts from unintentionally loosening and the attached parts from falling off due to vibration or other forces.
Barnhart Bolt located in Midland, TX and in Odessa, TX produces numerous types of fasteners and bolts including safety wire bolts and other custom fasteners in their expanding machine shops.
Each safety wire bolt needs to be cut to length, threaded, the end chamfered or angle cut, and then the head needs to be drilled. Barnhart Bolt produces safety wire bolts from 1/4" to 1 1/2" diameter.
The owners, Roger and Dax Barnhart both say that "the ChamferMate® and DrillMate® equipment we use is of the highest quality and reliability. These machines never break down."
