Product Details

The ARP 744-3750 is a premium 5-piece fastener kit featuring fine thread, 12-point bolts designed for high-performance applications on cars, boats, and trailers. These bolts are manufactured from specially alloyed ARP 300 stainless steel, offering 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 heads for superior grip and precise torque application
  • ARP 300 stainless steel construction with polished finish for exceptional corrosion resistance
  • 180,000 psi tensile strength for maximum clamping force and reliability
  • Maintenance-free design that resists rust and oxidation
  • Includes matching washers for complete installation
  • 5-piece kit provides convenience for multiple applications

ARP fasteners are engineered to exceed OEM specifications, making them ideal for differential installations, ring and pinion setups, and other critical fastening applications where reliability and strength are paramount. The polished stainless steel finish not only delivers outstanding durability but also provides a professional, show-quality appearance.

Awesome website easy to use and no looping!

Product was as described, great price and reasonable shipping cost. Shipping was also very quick.

Quick shipping on my order. Thanks

Wow. Ordered it on a Wednesday got it in 2 days....amazing....and to top it off my mandrel bent ss tubing was packaged infinitely better then I would of imagined. The price was amazing. I literally have no complaints. I will definitely order again. I will say that items on their website were not labeled well so I used vibrants website to look up part numbers so I could get the right parts. Search engine wouldn't bring up items via part number. Kinda confusing but for all I got simply awesome.

Great customer service answered my question with confidence and knowledge

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

Autoplicity had the best price for my Thule 867 roof rack cargo bag. It was easy to pay thru my Amazon accont and the order shipped within 24 hours of my placing the order.
