Fixture for drilling bolt heads

[Morgan]

I think this would be the place to ask this question. Which fixture for drilling bolt heads for safety wire is considered the “Cadillac” of the industry?
Would appreciate any input.

Thanks Ron

The: "Bought them already drilled" Cadillac price tag says it all.

Good question. It used to be addressed in 43.13 to drill bolt heads, but I have never actually seen a jig or block for doing so.

Part 91 might still be ok, but drilled and non drilled are different part numbers for 121 Operations.

HAHA yes

You want to make a tool a lot of people would buy. A jig that allows you to drill through tubing perfectly centered.
NO matter how hard I try, it is always a little off center.

Boeing and Airbus US carriers fly are SAE. Do you run into metric fasteners.

[Jmann]

Yes, you work in GA long enough, you will see an odd fastener that is metric due to pilot maintenance. NAPA (National Aircraft Parts Association) has great stock....LOL.

I see Diamond aircraft quite a bit, they are metric. Rotax engines are metric as well. Airliners not at all. Business aircraft I would say not but I do not know them well.

Old Convairs were BS
I think Saab and BAE have some metric, but usually only allen head stuff. Not bolts.
