commerical bolt or nut lock plates - US sources?
(OP)
In an effort to prevent fastener loosening Some equipment in some industries uses devices (lock plates) that engage the head of a bolt or nut and is in turn welded to the secured component. Sometimes bolts and huts are welded to the component (sometimes called "killed") to accomplish the same thing, but with the risk of compromising the fastener's metallurgy. I am an advocate of proper and adequate tightening as the most important means of keeping fasteners tight, but understand that preventing fastener loss is a reasonable back up plan. Rather than try to custom fabricate lock plates I think buying commercially available ones makes sense.
There are apparently DIN specs for devices called bridge clamps that seem to be serve the function.

Does anyone know of sources for Inch and metric lockplates?

With one simple hand-held tool and 5 minutes (with practice) the job is done. Removable in seconds without any damage to the bolt or the component material. There is a corresponding locking mechanism for nuts. Very common on aircraft fasteners. The bolts are ordered with holes pre-drilled through the head and/or the shank to allow the wire to pass through.
