Blue Aluminum T-Bar Wing Nut 4-3/4In With 1/4-20

The Blue Aluminum T-Bar Wing Nut 4-3/4In With 1/4-20 from Racing Power Co-Packaged is a precision fastener engineered for engine builders, performance mechanics, and automotive enthusiasts working on custom carburetors, intake manifolds, and fuel system components. This wing nut delivers the quick-access convenience that high-performance engine builds demand, allowing technicians to make rapid adjustments without requiring dedicated wrenches or socket sets. Built for serious engine modifications and competition-grade installations, it's become a staple in hot rod shops and professional machine facilities.

Manufactured from lightweight aluminum, this T-bar wing nut combines corrosion resistance with minimal weight penalty—critical attributes in engine compartments where thermal cycling and fuel exposure demand durability. The 1/4-20 thread pitch (standard SAE coarse thread) ensures universal compatibility with aftermarket carburetors, fuel blocks, and custom intake adapters common in street and competition builds. The 4-3/4-inch overall length provides leverage for hand-tight sealing without stripping delicate aluminum components, while the anodized blue finish protects against oxidation and provides visual identification in tight engine bays. The compact 0.4-pound weight and slim profile (0.65 inches wide) allow flush mounting in congested carburetor and air cleaner assemblies.

This wing nut is ideal for builders assembling fuel system transitions, manifold adapters, and velocity-stack carburetors where repeated adjustments occur during tuning and testing phases. Its hand-operated design eliminates the need for additional tools during dyno sessions or track days, reducing downtime between baseline runs and jetting changes. Whether you're transitioning between carb spacers, securing fuel block adapters on EFI conversions, or finalizing intake manifold bolting on an LS or big-block build, the Racing Power Co-Packaged design delivers reliability without compromise. Compatible with 1/4-20 studs and threaded holes across virtually all aftermarket carburetor platforms and custom intake systems.
