Product Details

The Dorman 610-191 is a direct replacement wheel stud designed to restore safe and secure wheel mounting on a wide range of vehicles. This press-in style wheel stud features 1/2-20 thread pitch, a .621-inch knurl diameter, and 1.5-inch overall length, making it a versatile solution for many automotive applications.

Key Specifications:

  • Thread size: 1/2-20 UNF (Unified National Fine)
  • Knurl diameter: .621 inches for secure press-fit installation
  • Overall length: 1.5 inches
  • Serrated knurl design prevents rotation in the hub
  • Sold in package of 10 studs

Dorman wheel studs are manufactured from high-strength steel to meet or exceed OEM specifications. The serrated knurl ensures a tight interference fit in the wheel hub, preventing the stud from spinning during installation or removal of lug nuts. This replacement stud is ideal for repair shops and DIY mechanics looking for a reliable, cost-effective solution to damaged or worn wheel studs.

Note: Always verify thread pitch, knurl diameter, and length against your original stud before installation. Proper press-fit installation tools are recommended for best results.

simple website to navigate

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

Quick and easy and better bargain than competitors.

Easy and affordable!

Great prices on a lot of good stuff, shipping isn't what's listed in price comparison, but competitive.

The shipping was fast, although I couldn't get it the first day because they require signature for delivery. I guess it's an added safety measure. Thank you! Will shop buy from again!
