RLJ Posted April 23, 2021 Report Share Posted April 23, 2021 Anybody know the part number for the tall 8mm brass nut that connects exhaust pipe to exhaust manifold? Three are used on the flange connection. Are they still available from Nissan? Quote Link to comment
datzenmike Posted April 23, 2021 Report Share Posted April 23, 2021 The 510 nut is 20602-A7100 but I don't know if brass or bronze or what. Probably just steel. I got some for my L16 exhaust manifold from a fastener shop. They are longer at 5/8" or around 15-16mm long but I also replaced the broken studs with longer ones. They probably were stainless and the extra length made up for the lack of strength that stainless has. Quote Link to comment
RLJ Posted April 23, 2021 Author Report Share Posted April 23, 2021 20602-A7100 is discontinued. Can find brass ones through hardware supply but not the tall ones. Like you said not sure if the originals I’m seeking were brass or bronze but they didn’t seize to the studs overtime. Quote Link to comment
banzai510(hainz) Posted April 23, 2021 Report Share Posted April 23, 2021 I used reg nuts with anti seize but zcardepot.com might have something. the orginal are NLA and I couldnt find any exact replacements Quote Link to comment
datzenmike Posted April 23, 2021 Report Share Posted April 23, 2021 Get the thread size or take one with you to a fastener store. Get longer SS. Hell the studs that were on the L16 manifold only had threads where the nut was protecting them. Above the nut where the flange was it eroded down like a tooth pick. Quote Link to comment
