    Need nut, bolt, washer specs for Rohn 25 tower

    I'm going to try and get the tower up in the next few weeks. Does anyone know the sizes and grade specs for the nuts, bolts, and washers to put the thing together. I have the tower sections, but none of the hardware.

    Any help would be appreciated. I thank you for your support.

    At a minimum I would go with Grade 8 stainless. I have an area friend - Marty, N8XPK - who is a tower rigger. You might try getting in touch with him (bakertower_atsign_neo.rr.com) and asking his advice. Tell him I sent you.

    Yep.. Just grade 8 stainless. Lock washers and anti seeze will do ya just fine.. You don't need to buy them from Rohn. Call around, You'll find the best price. www.winetwork.org Len will tell you more info you need to know. His email is on the website.

    I figured Grade 8 stainless, but there are two sizes of bolts. Anyone know the size and length of the bolts?

    OK Heres the deal From da tower man. 5/16 fine thread 1 1/2 long is the one size and the other is 1/4 fine thread 1 1/2 long. He says don't waste your money on stainless. Reg Grade 8 is just fine. Lock washers and a dab of anti seeze so it comes apart in the future. Also knock the burrs and galvanizing out of the holes with spud pin.

    Don't forget to lube the leg interfaces, too (where one section goes into the next).

    I forget what we used to use for that, but it'll make it a lot easier to get the sections apart years from now. Bit of axle grease, maybe? Sucks when you have to dig out a scissor jack to pry the sections apart.
