5/16"-24 x 3-1/2" Grade 8 Yellow Zinc Finish Hex Cap Screw

Engineered for high-stress applications and critical mechanical assemblies, the 5/16"-24 x 3-1/2" Grade 8 Hex Cap Screw (SKU: 18807) provides the uncompromising strength and reliability required for heavy-duty projects. Manufactured from high-strength medium carbon alloy steel and quenched and tempered for maximum durability, Grade 8 fasteners are designed to withstand significantly higher tensile loads than standard Grade 2 or Grade 5 bolts. This specific hex cap screw features a fine thread pitch (24 TPI), offering superior vibration resistance and greater clamping force compared to coarse-threaded alternatives. The 3-1/2" length makes it an ideal choice for securing thick components in automotive, industrial, and agricultural machinery. To ensure long-lasting performance in demanding environments, the bolt is finished with a yellow zinc plating. This coating not only provides a distinct gold appearance for easy identification of Grade 8 hardware but also offers an essential layer of corrosion and rust protection. Whether you are performing structural repairs, engine work, or industrial equipment maintenance, this hex head bolt provides the precision fit and safety margin your work demands. The hex head design allows for high-torque installation with standard wrenches or sockets, ensuring a secure, permanent hold. Trust SKU 18807 for projects where failure is not an option.
