S/S Header Bolt Kit - 6pt. 3/8-16 x 1in (16)

The STAGE 8 FASTENERS Stainless Steel Header Bolt Kit—3/8-16 x 1 inch, 6-point, set of 16—delivers the locking fastener integrity serious engine builders and performance technicians demand. Designed for Small Block Ford applications, these 3/8-16 header bolts combine stainless steel construction with a locking hex head design to eliminate vibration-induced loosening during sustained high-RPM operation. The 6-point head geometry provides positive engagement with standard wrenches and sockets, reducing rounding risk compared to 12-point alternatives.

Each bolt measures 1 inch in length with a 3/8-inch-16 thread pitch—the OEM fastener specification for Small Block Ford cylinder heads. Stainless steel material resists corrosion from exhaust heat cycling and moisture exposure, critical for engine compartment longevity. The integrated locking mechanism within the fastener design (unlike loose lock washers) maintains clamp load consistency across thermal cycles, preventing the creep that degrades header seal integrity on modified or turbocharged platforms. Complete set of 16 pieces covers a full Small Block Ford header assembly.

Engine builders, fabrication shops, and performance enthusiasts specify STAGE 8 locking fasteners for street engines, race builds, and restorations where header separation or stud pull-through creates risk. The stainless finish handles both visible engine bays and hidden manifold applications. If your Small Block Ford project requires header fasteners that won't back out under load, this kit eliminates the need for separate washers, lock nuts, or threadlocker compounds.

STAGE 8 FASTENERS holds industry credibility among engine machine shops and OEM restoration specialists for precision fastener engineering. These bolts comply with the fastener grade and thread specifications required for proper Small Block Ford assembly and are engineered to maintain torque retention in sustained high-temperature environments.
