Oval Head Quick Fastener 5/16 x .500

The Oval Head Quick Fastener 5/16 x .500 by Moroso is an essential component for engine builders, hot rodders, and serious mechanics tackling custom automotive projects. These fasteners are designed for applications where speed of assembly and reliable clamping are critical, such as securing intake manifolds, carburetor bases, and aluminum valve covers.

Quick fasteners eliminate the need for traditional bolts and washers, delivering faster builds without sacrificing holding power. The 5/16-inch diameter with a 0.500-inch grip length provides optimal clamping force for sheet metal, gasket stacks, and aluminum components, ensuring consistent pressure distribution and reducing vibration-induced loosening.

Engineers and technicians rely on the Oval Head Quick Fastener for manifold work, fuel system component mounting, and custom intake fabrication on both carburetor and EFI platforms. Its durable design resists corrosion and maintains tension through thermal cycling, making it suitable for both street and race applications.
