As of June 1, 2019, we are no longer providing the 1" -8* 2 1/4" full threaded A325 bolt, the 1" Heavy Hex Nut Grade C A563 nut or the 1" F436 washers for the Solar Carport systems and the 5-High posted Ground Mount system. We have made this change because we are now providing an A325 Tension Control Bolt assembly, which includes the bolt, the 1" nut and the 1" F436 washer. If you choose to use the new TC Bolt, the cost will be $3.00 per bolt assembly vs the $3.70 you would pay for nuts, bolts and F436 washers.
Above is a picture of the TC bolt we will be providing.
The TC bolts we will provide require the specific TONE TC Bolt Shear Wrench, with the socket and inner socket specific to the TC bolt we will provide. This method will be a savings in the long run, with respect to cost of fasteners, time to install the bolts, which translates to less labor. Once your crew get a handle on using the gun, it will take seconds to install a bolt. When it’s torqued to the proper point, the end of the bolt will break off. Another benefit is that inspectors won’t be checking torque values on bolts when they see that TC bolts were used.
If you choose to continue to use the nut, bolts and washers previously provided for projects, you would now source those from a local fastener provider. Please contact us for the specs for each if that is your preference.
