About Auto Racing Products

ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.

Ultimate Fastener Integrity: Auto Racing Products Chamfered Chromoly Flat Washers (1/2" ID x 7/8" OD)

For builds where compromise is not an option, the Auto Racing Products Chamfered Chromoly Flat Washers (1/2" ID x 7/8" OD) provide an unparalleled level of fastening security and component protection. These premium washers are meticulously crafted with a chamfered edge, a critical design feature that ensures optimal seating, reduces stress points, and prevents surface damage, making them indispensable for high-performance automotive, motorsports, and heavy-duty industrial applications. Elevate your assembly's reliability with hardware built to exceed expectations.

Engineered for Superior Performance and Protection

These special purpose flat washers combine the best of material science and precision manufacturing:

  • High-Grade Chromoly Construction: Chosen for its exceptional tensile strength and resistance to fatigue, chromoly steel ensures these washers can withstand the most rigorous conditions, maintaining structural integrity under high torque and dynamic loads.
  • Durable Black Oxide Finish: The protective black oxide coating provides a robust barrier against corrosion, rust, and chemical degradation, extending the lifespan of the washers and maintaining a clean, professional appearance in any environment.
  • Precision Chamfered Edge: The expertly machined chamfer allows for a smoother transition and better fitment, particularly beneficial when working with fasteners that have a radius under the head, minimizing stress concentrations and preventing galling.
  • Optimal Load Distribution: With a substantial 7/8" outer diameter, these washers effectively spread the clamping force, preventing localized pressure points and safeguarding softer materials from embedment or damage, ensuring a more secure and lasting connection.

Versatile Applications with Exacting Fitment

Featuring a 1/2" (0.5 inches) inner diameter and 7/8" (0.875 inches) outer diameter, coupled with a consistent 0.12" thickness, this 10-piece set of chamfered flat washers is designed for a broad spectrum of critical fastening tasks. They are ideal for engine components, driveline assemblies, suspension systems, and any application where precise fitment, superior strength, and enhanced durability are non-negotiable. Trust in ARP for your most important connections.

Specifications:

  • Material: Chromoly Steel
  • Finish: Black Oxide
  • Inner Diameter (ID): 0.5 in (1/2")
  • Outer Diameter (OD): 0.875 in (7/8")
