OT: Darn &?%#@%! screw!!!

Before trying to impact torque the screw loose.(Which is the last resort)

First place a small amount of "Liquid Wrench" (available at most Automotive and Hardware Stores)Do not apply excessively, Just enough to wet the ring around the screw.

Allow to set for 1 hour then wet again and allow to set.

Do not rush the act apply many times over a 24 hour period.

Then;

Try using a screwdriver that you do not mind hammering the end of the handle while applying torque by hand to loosen the screw.

FIRST APPLY TORQUE BY HAND THEN TAP THE END OF THE HANDLE OF THE SCREWDRIVER WHILE APPLYING THE TORQUE LIGHTLY AND TAP LIGHTLY AT FIRST THEN WITH INCREASING TORQUE AND HAMMERING.

KEEP INCREASING TORQUE AND IMPACT UNTIL THE SCREW LOOSENS OR BREAKS.

If you wish to use an Impact Driver Do this as above described in CAPITALS.

If Breaking the screw seems extreme I'm sorry,

I know of no other option !

If this happens you must then employ the aid of a "GOOD GUNSMITH" to drill and tap out the remains of the broken screw .(possibly a special thread not usually found in Hardware Stores)

Wishing you LOTS OF LUCK !
