Hex Head Bolt 1/4-20 x 5 Grade 5 5pk

The ALLSTAR PERFORMANCE Hex Head Bolt 1/4-20 x 5 Grade 5 5-pack (SKU ALL 16214) is a precision fastener engineered for high-demand mechanical applications requiring reliable clamping force and corrosion resistance. Grade 5 bolts deliver approximately 130,000 PSI tensile strength, making them suitable for critical assemblies in motorsport, heavy equipment, firearms components, and tactical gear fabrication where standard fasteners would fail under load or vibration.

The 1/4-20 thread specification (1/4-inch diameter, 20 threads per inch) paired with the 5-inch length and 7/16-inch hex head provides optimal engagement depth for component assembly without excess protrusion. Zinc oxide plating offers baseline corrosion protection suitable for indoor and controlled environments. The Grade 5 rating ensures these bolts maintain clamp load under thermal cycling and mechanical stress—critical when fastening serialized components or structural assemblies that cannot tolerate fastener relaxation. This five-pack format provides working inventory for shop maintenance, repairs, or equipment builds without waste.

Users working in gunsmithing, mechanical assembly, equipment restoration, or heavy-duty field maintenance rely on Grade 5 fasteners when OEM specifications demand strength and reliability. The 7/16-inch hex head accepts standard wrenches and sockets, enabling efficient installation without specialized tooling. Whether replacing worn fasteners in existing assemblies or specifying fasteners for new builds, the combination of Grade 5 strength, zinc plating durability, and universal 1/4-20 thread compatibility makes this pack a foundational choice for precision mechanical work.
