Hex Head Bolt 1/4-28 x 1-1/2 Grade 5 10pk

The Hex Head Bolt 1/4-28 x 1-1/2 Grade 5 10-pack from ALLSTAR PERFORMANCE is a reliable fastening solution designed for automotive enthusiasts engaged in engine builds, suspension upgrades, and frame modifications. These bolts are essential structural connectors in high-vibration environments, particularly in applications like motor mounts and performance suspension linkage.

Manufactured to Grade 5 specifications, these fasteners typically exhibit a tensile strength of around 120,000 PSI, making them a preferred choice for performance automotive work. The 1/4-28 thread pitch offers fine threading, which can generate a strong clamping force and resist loosening under extreme vibration, although the effectiveness can vary based on specific applications.

Ideal for tasks such as assembling stroker engines or installing roll cages, having Grade 5 fasteners on hand helps prevent issues like stripped threads or loose connections. The hex head design ensures a reliable grip for wrenches and distributes load effectively, reducing the risk of bolt-head stripping during high-torque assembly or repeated disassembly.
