ARP 674-1005 Metric Stainless Steel Bolt - 12-Point Kit 5-Pack

The ARP 674-1005 is a 5-piece kit of premium metric 12-point bolts engineered for high-performance applications. These fasteners are manufactured from ARP's specially alloyed 300 series stainless steel or heat-treated 8740 chrome moly with a black oxide finish, delivering a nominal tensile strength of 180,000 psi—significantly exceeding Grade 8 hardware standards for superior clamping force and reliability.

ARP fasteners are trusted by professional engine builders and enthusiasts for their exceptional strength-to-weight ratio and precision manufacturing. The 12-point head design allows for finer angle engagement during installation, making them ideal for tight clearance applications where standard 6-point bolts may be difficult to position.

Key Features:

• Premium ARP 300 stainless steel construction with polished finish
• 180,000 psi tensile strength rating
• 12-point head design for improved wrench engagement
• Corrosion-resistant and virtually maintenance-free
