S/S Bolt Kit - 6pt. (5) 3/8-24 x 1.250

The ARP Stainless Steel Bolt Kit – 6pt. (Set of 5) 3/8-24 x 1.250 delivers precision fastening for critical engine and component assembly where corrosion resistance and reliability are non-negotiable. ARP bolts are engineered to exacting tolerances and manufactured from premium stainless steel, making them the standard choice across automotive, motorsport, and precision mechanical applications where fastener integrity directly impacts performance and safety.

Each bolt in this 5-piece set features a 3/8-inch diameter with 24 threads per inch (3/8-24 thread specification), 1.250-inch length, and a 3/8-inch hex head for reliable wrench engagement. The polished stainless steel construction resists oxidation in marine, humid, and chemically harsh environments where standard steel fasteners would corrode or degrade. The 6-point head design ensures consistent clamping force distribution and reduces the risk of head stripping during installation and removal cycles. These specifications make the kit suitable for engine block work, exhaust system assembly, fuel system applications, and any critical joint where fatigue resistance and vibration security matter.

Operators and builders rely on ARP fasteners when OEM hardware won't suffice—particularly in high-vibration environments, extreme-temperature cycles, or applications requiring upgrade materials. The universal design of this bolt kit makes it a practical addition to tool kits, machine shops, motorsport facilities, and field repair stations. At 0.3 lbs for the complete set, this compact kit stores easily in toolboxes and vehicles without bulk, ensuring the right fastener is available when needed in the field.
