Interesting info. Which brings up a question I've been looking for the answer to for several years. I've installed numerous M2 Orion 2800 rotators over the years and invariably the mast turns eventua

Bolts loosen because rotational effects work on them torque wise. For example if you put a Phillips head bit into an electric drill and tighten the chuck, the bit will drive screws and never loosen.

Unless you are sealing leaks, Loctite is a band-aid for design problems. It almost never works anyway, as you found out. Critical automotive bolts are actually lubricated rather than glued! I lubric

The chart below gives you the middle of the road for most bolts and nut in Metal to Metal contact as to proper Torque spec. I honestly believe that anyone doing Tower/Antenna work should own a 3/8 an

As I seem to recall reading somewhere that it is desirable to have the mast clamp slip for situations of a very large beam load and a high wind; that it is better for an occasional slip than to "bust

Here's a comprehensive guide to fasteners and their use. Includes 11 pages on galling, corrosion, high temperature effects, joint design and tension control in a bolted joint, including a description

In fact my recently concluded study has revealed the HAMs in America rotate their rotor's counter clockwise precisely twice as often as they rotate them in the clockwise direction. I am now off to C
