Ground Rod Clamp Torque

[A.D. Miller]

Does anyone know the torque requirements for ground rod clamp bolts/screws? The only reference I have found is to UL 486, but hate to buy it if I don't need it. Thanks.

see last page.

Also they do make 'torque shear head at proper installation torque (nonremovable)'
