Metric 8mm Exhaust Manifold Studs & Lock Nuts

Pack of 2 studs & 2 nuts

M8 x 1.25  - Premium Quality - Ships Fast!

 Product Description:  This is a metric M8x1.25 exhaust manifold stud & nut set, consisting of 2 studs and 2 nuts. The thread size/pitch of both stud and nut is M8x1.25. The stud has an overall length of 46mm, with two unequal-length threaded ends (13.5mm and 25mm). The length of the unthreaded center portion is about 8mm.  The nut hex size is 12mm (requires a 12mm wrench or socket).  The flanged nuts feature a self-locking design, so when they are fastened to a stud by hand, they will stop when they reach the "locking" portion.  You will then need a wrench or socket to fasten it further, at which point it will "lock" in place.  Self-locking nuts are especially useful as for exhaust systems, where vibrations could cause regular, non-locking nuts to gradually loosen and come off.  These studs and nuts are premium quality, high strength and temperature resistant for exhaust system applications.

Applications: M8x1.25 is a popular size for the exhaust manifold of many import vehicles, such as Acura, Honda, Nissan, Infiniti, Mitsubishi, Volkswagen, etc. If you are uncertain what size you need, feel free to ask us before you purchase.  You can usually determine what size you need by checking the hex size of the nut.  If a 12mm or 13mm socket / wrench fits the nut, most likely you have 8mm studs/nuts.  If the nut requires a 14mm socket/wrench,  then likely you have 10mm studs/nuts. If you need the larger 10mm studs/nuts, we have those available under a separate listing in our eBay store under "Specialty Hardware & Fasteners".
