The ALLSTAR PERFORMANCE Hex Head Bolt 1/4-20 x 2 Grade 5 10-pack is a precision fastener engineered for applications requiring structural reliability under load and vibration. Grade 5 specification delivers tensile strength rated at 120,000 psi, making these bolts suitable for engine assembly, suspension systems, equipment mounting, and other critical assembly work where fastener failure is not an option. The 7/16-inch hex head accommodates standard socket and wrench sizing, while the 1/4-20 thread pitch and 2-inch length address standard fastening dimensions across automotive, mechanical, and industrial applications.
Each bolt is manufactured from steel and finished with zinc oxide coating to provide corrosion resistance during storage and use. The zinc oxide treatment extends service life in humid or variable storage conditions without compromising the fastener's core strength. Grade 5 bolts generate superior clamping force compared to lower grades, a critical factor when fastening components subject to thermal cycling, vibration, or sustained load. The 10-pack quantity offers practical economics for build-outs, repairs, and spare inventory without excess bulk.
This fastener set serves mechanics, restoration specialists, equipment technicians, and equipment operators who depend on consistent, traceable fastening standards. Whether securing engine components, mounting brackets, or assembling structural assemblies, Grade 5 specification ensures the bolt will perform at rated tension without deformation or failure. The hex head design permits quick installation and removal using common hand tools and powered drivers, reducing assembly time in field or shop environments.
Grade 5 fasteners occupy the middle tier of the tensile strength spectrum—stronger than common Grade 2 bolts but less costly and more widely available than premium Grades 8 or higher. This positioning makes Grade 5 the standard choice for most automotive and light-industrial fastening, balancing performance, cost, and parts availability. The 1/4-20 thread and 2-inch length are among the most commonly specified dimensions across fastener applications.
