Stainless Hardware -- Tilt Base
The complete hardware set for the Greyline Tilt-Up Base: four 3/8"-16 x 3.25" pivot bolts, four nuts, eight washers, and eight 1/4"-20 section bolts -- in stainless. The pivot is the one joint on the antenna that moves by design, and it lives at ground level where moisture collects. Plated hardware there is on a short clock; stainless ends it.
Check the rest of your hardware while you are down there. Stainless is mildly magnetic, so a light pull on a magnet is normal; plated steel grabs hard, and it rusts. Rust is the verdict. Replace with stainless, always.
The right way to swap it -- pivot bolts last, antenna supported -- is written up in our assembly documents.
