Product Details

The ARP 616-3750 is a premium 5-piece bolt kit featuring high-quality stainless steel or chrome moly fasteners designed for automotive, marine, and trailer applications. These fasteners are manufactured from specially alloyed ARP 300 stainless steel or heat-treated 8740 chrome moly with a black oxide finish, both nominally rated at 180,000 psi tensile strength—providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • 12-point head design for superior grip and torque application
  • 180,000 psi tensile strength for maximum holding power
  • ARP 300 stainless steel construction resists corrosion and rust
  • Polished stainless finish provides excellent appearance
  • Maintenance-free performance in harsh environments
  • Includes matching washers for complete installation
  • 5-piece kit provides convenient replacement quantity

ARP fasteners are engineered to exceed OEM specifications and deliver reliable performance in demanding applications. The 12-point head configuration allows for easier installation in tight spaces while distributing torque loads more evenly than standard hex heads. Whether you're securing engine components, chassis parts, or marine hardware, these premium bolts offer the strength and durability professionals demand.

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

Great prices & fast shipping.

They had the best price anywhere on the items I ordered(Recon Lights). Prompt emails and accurate tracking via UPS shipping. I'm pleased and will order more items now that I know they're "legit". Thanks Autoplicity!<br><br>Nick C.

quick and easy

Easy to do business with BEST PRICE anywhere!! Shipped and arrived quickly

I ordered this product and Wednesday in the morning and it was on my door step Thursday morning with regular shipping. The ordering process was super easy and the price was $35 cheaper than any other online retailer. The Rack is awesome, easy to assemble took me about 20 minutes by myself, put on my jeep hooked up the bikes and off I went, fantastic design, I highly recommend the Rola NV2 bike rack and highly recommend Autoplicity

Not sure if they overlooked my order but I didn't get my shipping info (3 days after ordered) until I emailed asking for status update. I received a response the following day and all my items ordered came 2 days later...much faster than I had anticipated considering the "delay" or lack thereof (5 days total). Long story short...items are as described, best prices (from what I can researched online for same items/brand) and resonable shipping prices. the selection and brand(s) offered were somewhat limited for my specific needs, otherwise I would've ordered more.
