Technical Threads supplies ASME SA453 Grade 660 (A-286) precipitation hardened incoloy fasteners for high-temperature, high-pressure applications on pressure vessels, including boilers, DA/DC tanks, exchangers, reboilers, aftercoolers, etc. The sizes typically supplied are 1/2″ through 2″. The specification is typically for fully threaded studs for extreme conditions. When applciations call for the “big three”, temperature, pressure and corrosion resistance, ASME SA453 is often found.

Material is made to order, but fully threaded studs are available from round bar stock for immediate shipment.
