Product Details

ARP's 200-8405 stainless steel washers are designed for general-purpose applications including accessory mounting, chassis components, and various automotive assemblies. These precision-engineered washers feature excellent corrosion resistance thanks to their stainless steel construction.

Key Features:

  • Designed for 5/16" shank bolts and studs
  • 9/16" outer diameter provides proper load distribution
  • Oversized inner diameter clears most under-bolt head radii
  • Stainless steel construction for superior corrosion resistance
  • Ideal for accessory mounting and chassis applications

Important Note: These washers are engineered for general-purpose use and are not hardened for critical high-stress applications such as cylinder heads, main caps, or connecting rod bolts. For those applications, ARP's hardened washers should be used instead.

ARP is a trusted name in fastener technology, providing quality components for automotive, racing, and performance applications. Each washer meets ARP's strict quality standards for precision and reliability.

i looked for a week to find the best price and autoplicity had the rest beat and they didnt charge me an outragous shipping and handling fee.... will use again...

Very good and easy experience! Items shipped out quickly. Definitely will do future business here.

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Autoplicity did a wonderful job, and was definitely the best price. I don't know how they do it, BUT I'll buy more from them. Amazingly swift delivery. GREAT SERVICE !!!!!!

You can tell customer service is important to this company. Not only were the prices lower than other places but they communicate the status of the order and shipping very well. They obviously care what people think. I was suspicious of all the positive comments but decide to try them anyways. Very happy I did and definitely plan on buying from them again.

Utilized customer support for question on particular item. Phone answered immediately, consultant answered questions and I was able to place order immediately. This second purchase was due to the initial experience. Will make future purchases from Autoplicity.

Great Price! Fast Shipping!

fast and easy
