ARP 711-2250 Stainless Steel 1/4-28 x 2.250 12-Point Bolt Kit

The ARP 711-2250 is a premium stainless steel bolt kit designed for universal automotive, marine, and powersports applications. Each kit includes five high-strength 1/4"-28 fine thread bolts with a 2.250" underhead length and precision-machined 12-point heads requiring a 5/16" socket.

Key Features:

• Manufactured from specially alloyed ARP 300 stainless steel rated at 170,000 psi tensile strength
• 12-point head design provides superior grip and reduces risk of rounding compared to hex heads
• Polished stainless steel finish offers excellent corrosion resistance and attractive appearance
• Fine thread 1/4"-28 pitch for applications requiring greater holding strength than coarse threads
• 2.250" underhead length with approximately 1.000" thread length
• Includes washers with each bolt for proper load distribution
• Maintenance-free construction resists rust and corrosion in harsh environments

ARP stainless steel fasteners provide a substantial safety margin over Grade 8 hardware, making them ideal for critical automotive, marine, and trailer applications where reliability and appearance matter. The 5/16" 12-point socket size allows for use in tight spaces where standard hex heads may not fit.
