2.4.3 Fastener Information
All threaded fasteners are galvanized, ASTM A325, high-strength, hexagonal-
head screws (equivalent to SAE Grade 5) or stainless steel. The anchor bolts
used in the foundation are made of SAE Grade 5 steel or better.
Each fastener must be correctly tightened at final assembly to ensure that it
will carry its design load without working loose under vibration and will not
allow slippage or separation of joined members. Thus, the structural
integrity and pointing accuracy of the total antenna system depends upon the
proper installation of quality fasteners.
This manual specifies the required torque value for installation of all major
structural fasteners. Refer to Table 2-2 for the specific torque values for each
fastener.
