Engineered for heavy-duty applications where failure is not an option, the 1/4"-20 x 2-1/2" Grade 8 Hex Cap Screw (SKU: 0115013) offers superior strength and reliability. Manufactured from high-strength medium carbon alloy steel, this fastener is heat-treated to achieve a minimum tensile strength of 150,000 psi. This makes it significantly stronger than standard Grade 5 bolts, providing the structural integrity needed for high-stress environments such as automotive repair, industrial machinery, and heavy equipment manufacturing. Each bolt features a distinctive yellow zinc dichromate finish. This protective plating serves two critical purposes: it provides an extra layer of corrosion and oxidation resistance—ideal for outdoor or humid environments—and offers the industry-standard visual identification for Grade 8 hardware. The 1/4"-20 coarse threading ensures a secure, cross-thread resistant fit, while the 2-1/2" length provides ample reach for thick assemblies or through-bolt applications. Designed with a precision-engineered hexagonal head, these screws allow for maximum torque application using standard wrenches or socket tools. Whether you are reinforcing a vehicle chassis or securing industrial mounts, these Grade 8 hex cap screws deliver the professional-grade durability and safety margins required for your most demanding projects.
