S/S Header Bolt Kit - 3/8 x .875 UHL (12)

The S/S Header Bolt Kit - 3/8 x .875 UHL (12) represents a precision fastening solution designed for high-performance engine builders, motorsports technicians, and tactical firearms manufacturers who demand reliable, corrosion-resistant fasteners. ARP's stainless steel header bolts serve critical functions in applications where vibration, thermal cycling, and exposure demand superior material integrity. This 12-piece kit provides the fastening backbone for custom builds and field repairs where standard hardware would fail under sustained stress.

These 3/8-16 inch thread fasteners measure 0.875 inches in length with a polished hex head design that facilitates secure installation and removal in tight engine compartments and mechanical assemblies. ARP's proprietary stainless steel composition resists salt spray, high-temperature oxidation, and chemical corrosion—critical for applications subject to harsh environmental conditions or marine exposure. The drilled design allows for safety-wire application, a mandatory feature in military and law enforcement vehicle maintenance protocols that require positive retention against vibration-induced loosening.

Operators and technicians working with specialized engine builds, armored platform maintenance, or precision tactical equipment benefit most from this kit's reliability and uniformity. The universal compatibility of these 3/8-16 header bolts extends across multiple platforms—from custom motorsports installations to military vehicle restoration and firearms manufacturing. Installation requires standard hex sockets and torque specifications appropriate to the application; ARP's polished finish aids corrosion prevention and visual inspection during routine maintenance checks.
