pug Posted February 3, 2011 Share Posted February 3, 2011 Is there a differance between 3/8 thread bolt and a 3/8 pipe thread bolt. thanks Link to comment Share on other sites More sharing options...
dasbulliwagen Posted February 3, 2011 Share Posted February 3, 2011 The pipe thread will be tapered to provide a tighter seal as it threads in. Not sure if the thread pitch and threads per inch are the same or not though. Link to comment Share on other sites More sharing options...
pug Posted February 3, 2011 Author Share Posted February 3, 2011 Is it a standard tap i can get at auto part store or hardware. thanks Link to comment Share on other sites More sharing options...
mvusse Posted February 3, 2011 Share Posted February 3, 2011 3/8 pipe thread is also 1/2" or so. It is the thread on the outside of a standard pipe with an inside diameter of 3/8". I get individual taps from Ziegler Bolt and Nut. Imagine Fastenall will also have them. Hardware stores *migh*. Sears and Harbor Freight sell kits with an assortment of different sizes.

johnnyc Posted February 3, 2011 Share Posted February 3, 2011 So which is it that you need? 3/8" or 3/8" pipe thread? If you need 3/8" pipe thread, make sure the tap you buy says "3/8" NPT". Link to comment Share on other sites More sharing options...

Eagle Posted February 4, 2011 Share Posted February 4, 2011 3/8 pipe thread Then you need the local PLUMBING parts store, not the local auto parts store. Although 3/8" NPT isn't that unusual -- Sears will probably have it. Link to comment Share on other sites More sharing options...
