Hex Head Bolt 3/8-16 x 6 Grade 5 5pk

The Hex Head Bolt 3/8-16 x 6 Grade 5 5pk from Allstar Performance delivers reliable fastening for tactical equipment builds, vehicle maintenance, and firearms assembly where precision and durability are non-negotiable. This five-piece set addresses the reality that quality hardware failures in the field create cascading malfunctions—whether securing rail systems, mounting accessories, or assembling load-bearing components. Grade 5 bolts provide the strength margin operators and mechanics demand when standard fasteners leave room for doubt.

Each bolt features a 3/8-16 thread pitch, 6-inch length, and 9/16-inch hex head sized for standard metric wrenches and sockets, enabling tool compatibility across most operational environments. Grade 5 steel construction with zinc-oxide plating resists corrosion during storage and field use while maintaining consistent torque characteristics across temperature swings—critical when securing optics, handguards, or chassis components that demand repeatable preload. The hex head design distributes load evenly, reducing cam-out risk during installation and removal under combat or workshop conditions.

Law enforcement and military armorers rely on Grade 5 bolts for permanent or semi-permanent mounting where fastener failure creates safety liability. The five-bolt quantity accommodates redundancy in builds while remaining compact for emergency repair kits or inventory replacement. These fasteners integrate into AR-platform upper receivers, chassis systems, scope ring bases, and vehicle-mounted tactical platforms where yield strength and fatigue resistance directly impact operational reliability. Stock multiple sets for maintenance cycles and field-expedient repairs.
