Triumph Exhaust Clamp Nut(s) 10-32 TPI PN# 21-7009

This nut is used with a 10-32 panhead screw to tighten the finned exhaust clamp, as used on the 1973-1980 Triumph 750 twins with 1-3/8″ exhaust pipes.

The plain nut is threaded to 10-32 TPI and is zinc-plated for corrosion resistance.

When used with the correct screw, this nut fastens the finned exhaust pipe clamps over the header pipes on the Triumph TR7 and T140 models. This nut is also used to secure the flasher clip to its spring on the models fitted with turn signals.

Care must be taken to not overtighten the hardware on the aluminum header clamps, as they are prone to cracking.
