These studs will not stretch or break as the factory steel items do. This will prevent repeated repairs as is commonplace with most weak factory steel studs.

As Inconel 625 has a high resistance to corrosion, these studs will not rust and cause issues down the track if components need to be removed for replacement or maintenance.

The ZD30 Manifold to EGR tube studs are 8 x 1.25mm on both ends of the stud. The overall length is 35.5mm.
9mm into the manifold, 6mm shank, and 19.5mm protruding.

    
The ZD30 Turbo to Dump pipe studs are identical to the EGR Tube, both are referred to as the “Short Stud in these kits”

The Manifold to Turbo studs are 8 x 1.25mm on both ends of the stud. The overall length is 43.5mm.

9mm into the manifold, 12mm Shank and 22mm protruding.

These studs have a stamped internal 4mm hex drive to make them easy to fit and reduce the chance of thread damage by the use of external stud installation tools.

The prevailing torque lock nuts supplied in these kits are German made copper-coated steel with Australian made 316 grade stainless steel washers.

Inconel 625 offers superior resistance to fatigue from heat and pressure well above standard high-tensile steel fasteners which ensures the correct clamping pressure is always applied during its service life.
