Product Details

The ARP AM4500-2B is a premium individual head stud manufactured from ARP2000 alloy steel, designed for high-performance engine applications requiring superior clamping force and reliability. This precision-engineered fastener features a black oxide finish for corrosion resistance and is commonly used in BMW 2.5L engine builds and other applications requiring this specific thread configuration.

Key Specifications:

  • Material: ARP2000 alloy steel with 220,000 psi tensile strength
  • Overall length: 4.50 inches
  • Base thread size: M10 x 1.50mm
  • Top thread size: M10 x 1.25mm
  • Finish: Black oxide coating
  • Thread rolled to Mil-S-8879 specifications
  • Precision centerless-ground for exact tolerances

Features and Benefits:

  • ARP2000 material offers significantly higher strength than standard 8740 chromoly, making it ideal for forced induction and high-horsepower applications
  • Dual thread pitch design (1.50mm base, 1.25mm top) provides proper engagement for specific cylinder head and block combinations
  • Thread rolling after heat treatment provides up to 10 times greater fatigue strength than pre-threaded fasteners
  • Precision manufacturing ensures consistent clamping loads and proper head gasket sealing
  • Black oxide finish provides rust protection while maintaining dimensional accuracy

This stud is sold individually and does not include nuts or washers, which must be purchased separately. When installing ARP studs, always use ARP Ultra-Torque fastener assembly lubricant and follow the manufacturer's torque specifications for optimal performance and longevity.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

quick

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Quick and easy so far

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.
