Product Details

The ARP 663-1010 is a 5-piece metric hex bolt kit designed for differential, ring and pinion, and general automotive, marine, and trailer applications. These premium fasteners are manufactured from ARP's specially alloyed 300 stainless steel, delivering exceptional strength and corrosion resistance for critical installations.

Key Features:

  • Nominally rated at 180,000 psi tensile strength for superior safety margin over Grade 8 hardware
  • ARP 300 stainless steel construction with polished finish
  • 12-point hex head design for improved torque application and reduced fastener rounding
  • Includes matching washers for complete installation
  • Rust-resistant and maintenance-free for long-term reliability
  • Suitable for automotive differentials, marine environments, and trailer applications

ARP fasteners are engineered to provide the extra margin of safety demanded in high-performance and critical fastening applications. The stainless steel construction ensures these bolts will maintain their appearance and strength even in harsh environments where corrosion is a concern.

Quick delivery and the product was as advertised.

Great shopping experience

Auto parts store no longer stocked my color of paint touchup, glad you guys had some

Overall, I was pleased with the purchased despite a long waiting period for its arrival due to it coming directly from the manufacturer. Better communication around shipping ETA would have been preferred.

Listing info was very helpful. Great price.

As I tried to order this part, there was confusion with other sites as to the dimensions. Autoplicity provided complete and clear information - and the checkout process was simple too.

Very fair prices *thumbs up*

Fast& easy checkout, unfortunately no option for faster than ground shipping that I really need for this purchase. I will be vertu impressed if it gets sent out this morning & to me tomorrow

Order arrived super quick with top-notch customer service along the way. Best price for OEM quality.

Super fast shipping.<br>I ordered husky front and rear floor mat for 2012 Prius.<br>It was delivered in 2 business days.<br>The product quality is very good.<br><br>Thank you,
