TORQUING FOR SIGHT SCREWS
We tell the guys who ask to tighten "FINGER TIGHT". That means as tight as your man hands will allow. But the questions persist as well as guys leaving their sight screws looser than DC Opsec.
So here we have the final word from the Dungeon.
We did some testing this morning to find a proper torque for the Glock
front sight screw.
We measured the length of (2) different screws, brand new out of the box. Then measured the length of each screw after different torques. Here are my results:
New: (1) .1172" long (2) .1172" long
5 in/lbs: (1) .1172" long (2) .1172" long
7 in/lbs. (1) .1173" long (2) .1174" long
10 in/lbs. (1) .1179" long (2) .1189" long
15 in/lbs. (1) .1205" long (2) .1210 long
Note: We stripped out (2) different front sight hex drivers getting the bolts to 15 in/lbs.
We recommend a torque of 5-7 in/lbs. You can achieve 5 in/lbs with only hand torque.
We also recommend that you de-grease and red loctite the front sight screw when installing.
Once the bolt has stretched more than .001" it is on its way to failure.
By the way...same for the RMR screws.
