Product Details

The ARP 624-2250 is a premium 5-piece hex bolt kit designed for high-performance automotive, marine, and trailer applications. These fasteners are manufactured from specially alloyed ARP 300 stainless steel, delivering a nominal tensile strength rating of 180,000 psi—providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • Premium ARP 300 stainless steel construction for maximum strength and corrosion resistance
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Polished stainless steel finish provides superior rust resistance and maintenance-free operation
  • 12-point head design for improved grip and installation accessibility
  • Includes washers for complete installation
  • Available in multiple sizes from 1/4" to 1/2" or M6 to M12 in various lengths

ARP fasteners are engineered for critical applications where reliability and safety are paramount. The corrosion-resistant stainless steel construction makes these bolts ideal for harsh environments including marine and trailer applications, while the high tensile strength ensures secure fastening in demanding automotive installations.

Good

I've been looking for these for a long time

Great prices. Fast Shipping. I would definitely do business again.

I ordered online with autoplicity via google checkout. It was easy and a real good price compared to other sites. The communication was great every step of the way. Order confirmation, order tracking number and shipping number. Super fast shipping for a heavy item (springs)and was in perfect condition. I Will shop with them again.

Hands down the best price on the Magnaflow catback I have seen by more than 20%. They were able to work out the ship-from-manufacturer tracking after a quick phone call. Will definately be recommending these guys to others.

Great prices on the products I want. Quick shipping.

Good prices...easy to navigate.

awesome price and super fast shipping. I will use again. Thanks
