IAG M10 Copper Exhaust Nuts (6 Pack) – Universal

IAG M10 Copper Exhaust Nuts — 6 Pack — Universal

Reliable Exhaust Fasteners for High-Temperature Applications
IAG M10 Copper Exhaust Nuts are the correct fasteners for high-temperature exhaust applications. Copper’s natural galling resistance and corrosion resistance at elevated temperatures make it the preferred material for exhaust flange nuts. Sold as a 6-pack — the quantity needed for most exhaust header installations.

DETAILS

• Material: Copper
• Thread size: M10
• Sold as 6-pack
• High-temperature compatible — resists galling and corrosion in exhaust applications
• Universal fit

Why Copper for Exhaust Fasteners
Standard steel nuts can gall, corrode, and seize when exposed to the heat cycling of an exhaust system. Copper maintains its corrosion resistance at elevated temperatures and resists galling against stainless steel exhaust studs — making it the preferred material for exhaust flange fasteners in performance applications.

Correct Quantity for Header Installations
A 6-pack provides the correct quantity for most Subaru exhaust header installations that use M10 exhaust studs and nuts.

Universal Application
These nuts are appropriate for any M10 exhaust application. Use them when replacing or reusing exhaust studs during header installation or exhaust manifold service.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available — and the engineering shows.

The RallySport Take

Copper M10 exhaust nuts are a small item that makes a real difference at the next exhaust service. Stainless header studs and copper nuts are a proven combination that removes easily at the next installation. Keep a pack in the toolbox.
