Product Details

The ARP 300-8333 is a set of ten high-strength 12-point hex nuts designed for demanding automotive and racing applications. Manufactured from premium 8740 chrome moly steel, these fasteners deliver exceptional strength and reliability where it matters most.

Key Specifications:

  • Thread size: 7/16 inch - 20 threads per inch
  • 12-point design for precise torque application and easy wrench positioning
  • 1/2 inch socket size for standard tool compatibility
  • Tensile strength: 180,000 PSI for maximum clamping force
  • Black oxide finish for corrosion resistance and professional appearance
  • Chrome moly steel construction for superior strength-to-weight ratio

ARP fasteners are precision CNC-machined and heat-treated to exacting standards, making them the preferred choice for engine builders and performance enthusiasts. The 12-point configuration allows for finer angle adjustments during installation compared to standard 6-point nuts. Each nut is manufactured in the USA and meets or exceeds OEM specifications for critical engine assembly applications.

This 10-piece pack provides sufficient quantity for typical cylinder head installations or other high-stress fastening requirements where reliability cannot be compromised.

Item and shipping as advertised.

The part was advertised as Goodyear but Goodyear sold or divested its interest in Gatorback belts to Continental. The belt I received was a Continental Elite Poly-V Belt which is the same as the Goodyear Gatorback belt. Autoplicity needs to update its website. I contacted Autoplicity after placing the order when I found on another website that Goodyear no longer makes Gatorback and asked what belt I was going to be sent. Justine O, a Senior Production Specialist directed me to the generic Goodyear website which had nothing about Gatorback belts because they no longer make Gatorback belts... thank you Justine O, Senior Production Specialist for absolutely nothing! Bottom line, Autoplicity may, or may not have what you want... but one thing is for certain, their customer service is as useless as every other customer service you have ever dealt with!!!

Nice easy to find the parts I need
