Product Description

FAA-PMA approved for Continental and Lycoming engines

Save money and get an enhanced product with McFarlane Stainless Steel Exhaust Nuts and Studs! A heat-treated, high-strength stainless alloy improvement, these studs are nitrocarburized Black Max™ coated for additional corrosion protection and resistance to galling. The studs are tap-end studs that come in various oversized options for use on Continental and Lycoming engines.

Lasts much longer! Save $$$ and labor!
Less stress on the exhaust flanges and gaskets as the engine heats up and cools down
Studs are nitrocarburized Black Max™ coating to resist galling and corrosion
Black Max™ prevents galvanic corrosion between stainless and aluminum cylinder
