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

The Allstar Performance Hex Head Bolt 1/2-13 x 1 Grade 5 10-pack delivers the fastening reliability required in high-stress mechanical applications. Each bolt features a 1/2-inch diameter with 13 threads per inch, 1-inch length, and a 3/4-inch hex head—a configuration widely used in motorsports assembly, engine builds, and precision machinery work. Grade 5 steel construction with zinc oxide coating provides corrosion resistance and tensile strength suitable for critical load-bearing connections.

Grade 5 classification indicates a minimum tensile strength of 120,000 PSI, making these fasteners appropriate for applications where standard hardware would fail under vibration or sustained load. The zinc oxide finish resists oxidation in both dry and humid environments, extending service life compared to plain steel alternatives. The universal design means these bolts work across multiple platforms and assembly contexts—race engine blocks, suspension components, frame repairs, and structural fabrication all benefit from consistent, verified fastening.

Mechanics, fabricators, and motorsports enthusiasts stock this bolt size because the 1/2-13 thread pitch balances holding power with ease of installation. The 10-pack format accommodates replacement needs and kit assembly without overbuying bulk quantities. Whether rebuilding a small-block engine, securing suspension geometry, or fabricating custom components, having Grade 5 fasteners on hand eliminates sourcing delays during critical repair windows.

TacticalSurplusUSA stocks industrial-grade fastening components trusted across restoration, fabrication, and performance engine work. This 10-pack of Grade 5 hex head bolts represents verified, repeatable fastening quality for applications where failure is not an option.
