What size are Cummins exhaust manifold bolts?
Product Specifications. Thread Size: M10 (10.0 mm.)
What grade bolt should I use for exhaust manifold?
You don’t need seriously strong bolts just to fasten manifolds to the heads. Grade 5 is fine.
What size are exhaust bolts?
The usual options of exhaust flanges are the 3 bolt or 2 bolt types. Usually, m10 with the 2 bolt option is helpful, and an m8 bolt for the 3 bolt. The recommended grade of bolts is 8.8 tensile or higher so that you can tighten them without stretching or breaking the bolts.
What size are header bolts?
Header Bolts, 3/8-16 x 1 Inch, Set/12.
Why do exhaust manifold bolts have spacers?
Spacers help to stop manifold bolts breaking due to the expansion and contraction due to heat. By fitting spacers and long bolts they have more room to grow without breaking.
Can you use regular bolts for exhaust manifold?
Super Moderator I agree, the bolts in place of studs and nuts would be okay. Be sure to observe the torque specs for the bolts, i.e. to be the same as the nuts on the studs. You dont want an exhaust manifold to be too tight – it interferes with the manifold expanding at a different rate than the head.
Can you use stainless steel bolts exhaust manifold?
There’s nothing wrong with them on exhaust systems but you really can’t put any serious torque on them because they are much lower tensile strength than alloy steel. They will stretch more so have to be tightened more than once after break in (in this application.
What size are exhaust clamp nuts?
Each exhaust clamp / muffler clamp has a different clamping diameter size to match various sized exhaust pipe applications. All clamps have an 11 gauge saddle, a 14 gauge clamp, and 3/8 inch diameter U-bolts with serrated nuts to provide secure connections.
Are all header bolts the same size?
It depends on the header flange. You need at least six threads engaged, preferably more. With my flanges, I had about three threads with the 3/4″ bolts.
Why stud is used instead of bolts?
Studs provide the ability to obtain much more accurate torque values because the studs don’t twist during tightening as do bolts. Because the studs remain stationary during nut tightening, the studs stretch in one axis alone, providing much more even and accurate clamping forces.
