Looking for a unique torque adapter.

Like these?

On old Caterpillar industrial engines, the fuel lines are all inline between the exhaust manifolds in the V on top of the engine. I used to use Snap On 12 point crowfoots to get in there and get them off or on. Worked great.

Would flare nut crowfoot wrenches fit?


Or is it the reach that is more important than the grip configuration?
Have to have both.

I have closed-end adapters that will reach, but there is not enough clearance around the bolt head for a closed-end.

When nothing else fit, I took a combination wrench, and cut out about 3/4” of the “ring” portion to make a crowfoot ring wrench. It was a good quality wrench, and it worked. It was an O2 sensor. Nothing else fit. I used a 7/8” Craftsman (made in the USA).

Perhaps take one of the closed ring wrench torque adapters, like you pictured, and cut out enough to slip over the stud. Buy a good one, like Stahlwille, Hazet, etc. it hurts to sacrifice a good wrench, but it gets the job done.

I later replaced that Craftsman with an eBay wrench, same vintage and markings.
 
What I have been doing is using a 10mm allen in the closed end of a stubby wrench. Most guys just skip it and give it German torque.

I can tell, because I end up replacing fasteners on everyone's aircraft but my own.

I've got authorization to purchase quite a few and have considered asking a local welding shop to make a run.
