Has anyone else had trouble with these four screws?
They are small, 4-40x1/2 cap head screws with 4-40 hex head crimped locknuts. For starters, even my smallest ignition wrenches were too big for the nuts. Pliers and adjustable wrenches were a poor and ineffective substitute. So I clamped the nuts into a vise to allow me to run the screws on prior to final panel installation.
Long story, short - I can't run those screws into those nuts due to the high locking torque, without destroying the nut in the vise or stripping the Allen socket in the screw cap, or both. Plus the screw seems a little long for the application and so requires the locknut to run way down the threaded length of the screw.
This remote switch is a small, lightweight plastic assembly, not needing such a robust installation. And, with a battery inside, needs periodic removal, meaning this is not a one-time heartburn.
Failing advice to the contrary, I plan to substitute non-locking hexnuts with either a touch of locktite, or a serrated or split-ring locking washer.
