Looking for information on part # 158740A.
I would like to know the thread pitch and diameter of this screw. Unfortunately the manufacture has used sever types of grip screws and I have ordered the wrong parts in the past.
The thread pitch and diameter of #158740 is 1/4" X 28.
Sorry apparently I'm an idiot. The pt.# I'm looking for is 1857410A. This time I cut and past the #
That's fine. I should have considered your heading of Armscor grip screw instead of just the item number given. Item #1857410 is a metric thread of M4 X 0 .5.
