Barrel nut size: M8

This Allen-type exhaust nut is used to fasten the heat exchangers to the bottom of the engine in places where only an Allen wrench can be used for torqueing.  

This exhaust barrel nut  replaces the normal M8 nut reference 911.010479A in locations where an open M8 wrench cannot be used.

Note: this part is sold separately but can also be included in one or more of our exhaust hardware kits. 

Other uses of this Allen nut are possible in the Porsche parts program. Please check with us for further details.

During replacement of your heat exchangers on your 911, 911 Turbo or 914-6, may we also suggest the following components:

911.010479A: M8 nut 911 (65-89)

911.010471B: Exhaust hexagonal head bolt, M10 911 (65-74) + 914-6 (70-72)

911.010471C: Exhaust copper nut, M10 911 (65-77) + 911 Turbo (75-77) + 914-6 + 356
