[TowerTalk] Rohn 45 Tower Bolts Torque Setting

[Robert Chudek - K0RC]

There is an interesting article about this, here: http://www.carcraft.com/techarticles/116_0609_using_rod_bolt_stretch_tool/index.html

I'll have to check my tower bolts to see if they have the "dimples" on both ends for centering the gauge.

Mark,

Using torque measurement is not accurate because of friction related to different surface tensions of the fasteners and the difference in lubricants.

To get an an accurate measurement you should read the bolt stretch with a dial indicator using a bolt stretch gauge.  One can be purchased here:  http://www.summitracing.com/parts/ARP-100-9942/  ;-)
