Product Information

Full details

This guide is for mechanics and automotive enthusiasts working on Alfa Romeo and Chrysler vehicles requiring robust exhaust manifold connections. The key benefit is the M8 x 1.25 double-ended threaded studs, offering secure and adaptable manifold mounting. A potential caveat is that the studs are slightly lubricated for corrosion prevention, which may require cleaning before final assembly depending on your specific application. This 5-piece set provides essential components for inlet and exhaust manifold tasks.

FAQs

What vehicles are these studs primarily designed for?

These studs are specifically designed for inlet and exhaust manifolds on Alfa Romeo and Chrysler vehicles.

What is the thread size and pitch?

The thread size is M8, with a pitch of 1.25mm.

Can the length of the stud be adjusted?

Yes, the longer, outer thread is designed to be cut to the required length for specific applications.

Why are the studs lightly lubricated?

The studs are slightly lubricated to help prevent corrosion during storage and transit.

What type of nuts are compatible with these studs?

They are compatible with M8 x 1.25 nuts, including standard hex, flanged, and self-locking variants.

How should I clean the studs if needed?

If the lubricant needs to be removed for your application, use a degreaser or solvent. A wire brush can also be used for cleaning threads.

What are the dimensions of the different thread sections?

The overall length is 43mm. The long thread is 17mm, the shoulder is 9mm, and the short thread is 17mm.

Troubleshooting

Stud does not thread in smoothly

Ensure the thread size (M8 x 1.25) matches the receiving hole. Check for any debris in the hole or damage to the stud threads. Clean the receiving threads if necessary.

Cut length is incorrect

Carefully re-measure and re-cut the stud to the correct length. Ensure you are using a precise measurement and a clean cutting method.

Lubricant interferes with assembly

Clean the lubricant from the stud threads using a degreaser or solvent before installation.

Nut will not tighten sufficiently

Verify that the nut thread size (M8 x 1.25) is correct. Ensure the stud is fully seated in its threaded hole and that no foreign material is preventing proper tightening.

Setup, Compatibility & Care

Setup:

  1. Determine the required length for the longer thread based on your manifold and cylinder head configuration.
  2. Carefully cut the longer thread to the desired length using an appropriate cutting tool (e.g., a hacksaw or metal-cutting saw).
  3. Clean any excess lubricant from the stud threads if required by your specific application or assembly process. Use a degreaser or solvent.
  4. Thread the studs into the manifold or cylinder head as per your vehicle's service manual.
  5. Install manifold components and secure with appropriate M8 x 1.25 nuts.

Compatibility:

  • Thread Size: M8 x 1.25 (pitch 1.25mm).
