Restore the correct tank fit on your vintage Triumph Trophy and other pre-unit twins with this OEM-spec petrol tank mounting bolt, part number 82-0966 (also listed as F966). This short, shouldered bolt is used to secure the underside of the fuel tank to the frame brackets on many 500cc and 650cc pre-unit models from the late 1940s through the mid-1950s.
Sized at 5/16 inch CEI x 26 TPI with a 15/16 inch under-head length, this bolt is designed to work with the original cupped washers and rubber isolators to properly rubber-mount the tank. Correct tank mounting helps control vibration, reduces stress on the tank, and preserves paint and brackets on restored machines.
Typical applications include pre-unit Triumph 5T, 6T, TR5, T100, T110 and TR6 twins circa 1946–1956 that use bolt-on tank mounts and rubber hardware. Always confirm fitment against your factory parts book to ensure this 82-0966 bolt is correct for your specific year and model before ordering.
