Hex Head Bolt 1/2-13 x 2 Grade 5 10pk

The Hex Head Bolt 1/2-13 x 2 Grade 5 10pk from ALLSTAR PERFORMANCE is the fastening foundation every serious engine builder, fabricator, and weekend warrior needs in their toolkit. These bolts serve critical roles in everything from intake manifold assembly and cylinder head work to suspension geometry modifications and custom chassis fabrication. Whether you're sourcing OEM-spec replacement fasteners or assembling a complete engine refresh, having a reliable 10-pack on hand eliminates the frustration of hunting for the right bolt mid-project.

Grade 5 rated fasteners deliver the tensile strength and shear resistance required for high-vibration engine compartment applications without the premium cost of Grade 8 hardware. The 1/2-13 thread specification—1/2 inch diameter with 13 threads per inch—is a standard coarse pitch that matches common ported holes across most domestic and import platforms, from classic muscle cars to modern LS-based swaps. The 2-inch length provides versatility across multi-piece assemblies where washers or spacers may be involved, and the hex head design ensures solid wrench engagement, eliminating the risk of fastener rounding that plagues Phillips or slotted alternatives during high-torque assembly work.

Mechanics and engine shops trust ALLSTAR PERFORMANCE fasteners for consistency, corrosion resistance, and dimensional accuracy—critical when tolerances stack across multiple bolted joints. The 10-pack quantity positions this product as both an immediate project solution and a smart inventory replenishment choice for shops doing regular intake, carburetor, or accessory bracket work. These bolts are equally suited to street builds, race engine assembly, and restoration work where original specification fasteners are required or preferred over mixed hardware.
