Product Details

The Dorman 803-020 is a Grade 5 hex head cap screw designed for automotive, marine, and general mechanical applications requiring medium-strength fastening. This zinc-plated steel bolt features 1/4-20 threading and measures 2 inches in length, providing reliable performance in a wide range of repair and assembly situations.

Key Specifications:

  • Grade 5 hardness rating for superior strength compared to standard Grade 2 fasteners
  • 1/4-20 UNC (Unified National Coarse) threading for broad compatibility
  • 2-inch overall length provides extended reach for deeper assemblies
  • Hex head design allows for secure tool grip and high torque application
  • Zinc-plated finish offers corrosion resistance for extended service life

Grade 5 fasteners are heat-treated medium carbon steel, offering tensile strength up to 120,000 PSI. This makes them ideal for automotive suspension components, engine mounts, chassis fastening, and other applications where standard hardware may be insufficient. The hex head configuration accepts standard wrenches and sockets for easy installation and removal.

I just placed an order, I cant really leave feedback yet?

Very high level of responsive customer service, wow! And the items arrived immediately, so fast I thought there might be a mistake. :D<br>thx Sean!

My first order and I must say, very impressive! Awesome prices and super-fast shipping direct from the manufacturer. Couldn't ask for more! I will return.

This was my first order with Autoplicity. Their prices were great, and the ordering process very easy. I was a little frustrated at first, as the order didn't arrive as expected. When I called, it took a little work, but I finally got the info that it was shipping from the manufacturer, and did get the tracking info. The parts arrived when tracking said it should. Would I place another order with Autoplicity? Short answer is yes!

Purchased K&N Filter. Excellent price and received filter as scheduled.
