Metric 8mm Exhaust Manifold Studs & Lock Nuts

6-pc set includes 3 studs & 3 nuts

M8 x 1.25  - Premium Quality - Made in USA or Japan

 Product Description:  This is a six-piece metric M8x1.25 exhaust manifold stud & nut set, consisting of 3 studs and 3 nuts. The thread size/pitch of both stud and nut is M8x1.25. The stud has an overall length of 47mm, with two unequal-length threaded ends (14mm and 23mm). The length of the unthreaded center portion is 10mm.  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.  Order by 3:00PM Pacific time, and this ships out the same day!

Ordering Guide: This listing is for a set of 3 studs and 3 nuts. If you need more than 3, you can order a quantity of "2", which will give you a total of 6 studs and 6 nuts; a quantity of "3" will give you a total of 9 studs and 9 nuts, and so on.

Applications: M8x1.25x47 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".
