Chromoly Strength For Critical Fastener Applications

Factory bolts are engineered for cost, not for the loads a built engine bay or high output chassis actually sees. This heat treated 8740 chromoly 12 point bolt is rated at 180,000 psi tensile strength, giving builders a drop in upgrade anywhere a reliable M6 fastener is required.

Key Features

  • Heat treated 8740 chromoly construction rated at 180,000 psi tensile strength
  • Black oxide finish for corrosion resistance and a clean appearance
  • 12 point head design allows a socket to grip more surface area than a hex head
  • M6 x 1.00 thread with a 35mm under head length
  • 8mm wrenching size for common socket compatibility
  • Sold in a pack of 5 bolts

Is this bolt stronger than a stock Grade 8 bolt?

Yes, its 180,000 psi tensile rating provides a substantial margin over standard Grade 8 hardware.

What is the recommended torque value for this bolt?

ARP publishes a general torque value of approximately 11 ft-lbs for M6 x 1.00 fasteners of this style, though final torque should follow the application specific service manual.

Install Instructions

  1. Clean and inspect the threaded bore before installing the new bolt
  2. Apply the recommended thread lubricant or ARP fastener assembly lubricant if specified for the application
  3. Thread the bolt in by hand to avoid cross threading
  4. Torque the bolt to the application specific torque value using an 8mm 12 point socket
  5. Recheck torque after initial break in if used in a high vibration location

ARP

ARP (Automotive Racing Products) is the world’s premier manufacturer of high-strength engine and driveline fasteners—head studs and bolts, main studs, rod bolts, and more—engineered and manufactured in-house from start to finish for race-proven reliability. With vertically integrated processes that include cold heading, machining, heat-treating, thread rolling after heat treat, and rigorous QA, ARP maintains aerospace-level certifications (ISO 9001 and AS9100) and validates every part for repeatable clamp load and fatigue resistance. Signature alloys such as 8740 chromoly, ARP2000, L19, and Custom Age 625+ deliver ultimate tensile strengths up to the super-alloy range, while ARP Ultra-Torque fastener assembly lubricant helps achieve consistent pre-load during installation. From street performance builds to professional motorsport programs, ARP fasteners provide precise fitment, superior metallurgy, and the durability needed to keep engines together at elevated cylinder pressures and...

ARP Head Studs

ARP Head Studs

ARP head studs replace factory head bolts with precision-machined threaded studs that provide more consistent and repeatable clamping force on the cylinder head gasket. Unlike head bolts that apply torque through both rotational and tensile forces, head studs allow the nut to be torqued concentrically on a stud that is already stationary, producing more even clamping load across the entire head gasket surface. Popular ARP Head Stud Applications ARP head studs are available for a wide range of performance and turbocharged engines including the Subaru EJ series, Honda K series and B series, Mitsubishi 4G63 and 4B11, Honda Civic and Integra, Toyota 2JZ-GTE, Nissan SR20DET and RB series, GM LS series, Ford Coyote and 5.0, and Dodge/Chrysler HEMI applications. ARP offers both 8740 chromoly and ARP2000 alloy head stud kits, with the ARP2000 material providing approximately 20 percent higher tensile strength for high-boost applications above 30 psi. Why are head studs preferred over head b...

Fabrication

Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...
