ARP Flexplate Bolt Kit 7/16-20 × 0.680 in, Set of 6 — Chromoly Black Oxide, 12-Point Head

ARP 200-2902 is a six-bolt flexplate fastener kit built from chromoly with a 12-point head and black oxide finish sized 7/16-20 × 0.680" for high-strength drivetrain assemblies.

This Pro Series flexplate bolt kit from ARP supplies six precision-ground bolts engineered for repeated torque and thermal cycling in automotive applications. Each fastener is manufactured in the USA from chromoly alloy, finished with black oxide for corrosion resistance, and designed to work where consistent clamp load and durability matter — especially in performance or rebuild projects.

What materials and dimensions define these flexplate bolts?

These bolts are forged from high-strength chromoly steel and specified at 7/16-20 thread pitch with a length of 0.680 inches. They use a 12-point head for tool engagement and are treated with a black oxide finish to reduce corrosion risk while maintaining reliable torque characteristics.

• Material: chromoly alloy for fatigue and tensile strength
• Thread: 7/16-20 (coarse-thread format)
• Length: 0.680 inches shank engagement
• Head: 12-point for stronger socket contact and less rounding
• Finish: black oxide to protect against surface rust

How do these bolts affect installation and torque consistency?

ARP Pro Series bolts are manufactured with tighter tolerances than many OE fasteners, which helps deliver repeatable clamp load when torqued to spec. That consistency reduces the chance of loosening or uneven seating that can occur under vibration or heat cycles in driveline components.

• Precision threads reduce galling and misalignment during installation
• 12-point head provides secure tool engagement for correct torque application
• Uniform length and finish promote even clamp across the flexplate
• Sold as a matched set of six to ensure uniform performance

Will these bolts fit my vehicle and how do I confirm compatibility?

These bolts are intended for applications that require 7/16-20 thread fasteners with a 0.680" length; verify your flexplate or flywheel bolt specifications against those dimensions. Check your service manual or measure an original bolt to confirm thread pitch, hex pattern, and engagement depth before ordering.

• Confirm thread size (7/16-20) and bolt length (0.680") match your application
• Verify 12-point head fits your torque tool or socket set
• Cross-check part number 200-2902 or 2002902 with vehicle references
• Made in USA — suits domestic performance builds and rebuilds

Who is this for? ARP 200-2902 is aimed at technicians, engine builders, and performance enthusiasts who need a matched set of chromoly flexplate bolts with consistent torque behavior and enhanced durability. If you're rebuilding an automatic transmission flexplate or upgrading to a higher-strength hardware solution for repeated track use, this kit supplies six precisely made bolts to replace worn or underspecified fasteners. The compact packaging and clear part number make it convenient for shops and DIY mechanics looking for reliable, USA-made drivetrain hardware.
