Product Details

The ARP 743-3250 is a premium 5-piece bolt kit featuring fine thread, 12-point head fasteners designed for high-performance applications on automotive, marine, and trailer assemblies. These bolts are manufactured from specially alloyed ARP 300 stainless steel with a nominally rated tensile strength of 180,000 psi, providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • Fine thread design with 12-point head configuration for superior grip and torque application
  • ARP 300 stainless steel construction with polished finish
  • 180,000 psi tensile strength rating for demanding applications
  • Excellent corrosion resistance for long-term durability
  • Includes matching washers for complete installation
  • Maintenance-free performance in harsh environments

ARP fasteners are engineered for enthusiasts who demand reliability and professional-grade quality. The 12-point head design allows for easier installation in tight spaces while distributing torque more evenly than standard hex head bolts. The polished stainless steel finish provides both functional corrosion protection and an attractive appearance.

Order 11001 was placed on Thurday and was shipped out on Monday. The item was cheaper than anywhere else on the web. I look forward to getting my new side steps. Thanks Autoplicity.

Great Price and Fast Shipping

Easy ordering and the best price I could find on the internet. However, I wouldn't have found this part by looking on the Autoplicity web site! The only way it showed up was doing a google search for that specific part.

I ordered a windshield wiper fluid reservoir. It came on time and was the product I needed. It fit perfectly and works great.

Best price no problem making order. Jesus is Gods gift to those who would believe

Best price available on the web. Fast shipping!
