Lucky me has only worked on two or three Weiserbolts. Someone made a round tool for removing the threaded on piece on the back of the plug.
Met a Weiser rep one time, who tried to assure me that his brand was great quality. The plastic they use for the cylinders is "Delrin 3, the same plastic they use for space helmets, and never needs lubrication". I don't think it's relevant about the space helmets. But, every Weiser I've seen has needed lubrication of some sort or other.
I got a deadbolt install job earlier this year. Got the deadbolts, and knobs in Schlage, cause I've had such good results with them. I will never again reccomend Schlage to anyone residential. The spring caps are miserable. The drivers are too short, and they saved 10 cents by making a one piece exterior knob instead of the old two piece knob.
Had a spring cap fly off, and I wasn't able to get it to stay back on.
Now, Kwikkie has me worried. The new "do everything" bolts I don't like. The ones that had the piece that slides out for 2 3/4 backset were a bad idea, and now they have a lift and slide extender for the knob lock bolts. The twist bolts for the 660 were acceptable.
