Quick Fastener Plate 1.75 OD X .43 ID x .032

The Quick Fastener Plate 1.75 OD x .43 ID x .032 from Moroso is a precision engineered component designed for high-performance engine builders, fabricators, and serious automotive enthusiasts tackling custom motor mounts, fuel system plumbing, and structural reinforcement work. This hardened steel plate serves as an essential backing washer and load-distribution component in applications where standard fasteners alone cannot safely transfer stress loads across thin materials or irregular surfaces. Whether you're building a stroker engine, installing a custom fuel cell, or securing auxiliary components in a race-ready platform, this Moroso fastener plate eliminates material deformation and fastener pull-through.

With an outer diameter of 1.75 inches and a precisely machined 0.43-inch inner diameter, the Quick Fastener Plate distributes clamping force evenly across a wide surface area while the 0.032-inch thickness maintains minimal bulk for tight engine bay fitment. The design accepts standard fasteners through its center bore, making it compatible with virtually any bolt or stud diameter in common automotive applications. Moroso's manufacturing standards ensure consistent hardness and flatness, critical when securing components to aluminum castings, thin sheet steel, or composite materials that would otherwise yield under concentrated bolt pressure. At just 0.085 pounds, this plate adds negligible weight while dramatically improving assembly reliability and longevity under vibration and thermal cycling.

Professional engine builders and fabricators rely on the Quick Fastener Plate 1.75 OD x .43 ID x .032 for motor mount bushings, turbo mounting bases, alternator and power steering pump brackets, and fuel pressure regulator mounting points where load concentration would otherwise crack aluminum or pull fasteners through thin materials. This plate is equally effective in chassis reinforcement, roll cage gusset backing, and suspension component attachment. For any build prioritizing durability and safety over cost-cutting, keeping several of these Moroso fastener plates in your shop inventory is fundamental—they're the difference between a reliable assembly that lasts and a catastrophic failure on the dyno or track.
