The Multiquip 915159 is a genuine OEM HHC Screw 7/16-14 x 1-1/2 Grade 8 designed for GRD8 series applications. As a direct Multiquip OEM part, 915159 meets the exact thread pitch, length, and strength grade specifications required for a correct and secure installation. Grade 8 hardware is specified for high-stress fastening points where tensile strength and torque retention are critical to safe machine operation. Order with confidence knowing this is the factory-correct fastener for your equipment.
Key Features
- Grade 8 Tensile Strength — Manufactured to Grade 8 specification, delivering the high tensile and proof load strength required at demanding fastening points on heavy-duty construction equipment.
- Exact Thread and Length Match — 7/16-14 UNC thread pitch and 1-1/2 inch length match the original fastener exactly, ensuring full thread engagement and correct clamp load without shimming or modification.
- Genuine OEM Part — Sourced directly from Multiquip, part 915159 carries the same material grade and dimensional tolerances as the fastener installed at the factory.
- Hex Head Cap Design — The hex head cap (HHC) profile is compatible with standard wrenching and torque tooling, allowing technicians to achieve proper torque spec cleanly and efficiently.
- Critical Fastener Integrity — Using an undersized or incorrect-grade fastener in a high-load application risks bolt stretch, joint loosening, or structural failure; 915159 eliminates that risk by supplying the correct-grade hardware every time.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket to a precise torque value. Grade 8 designation indicates the fastener is heat-treated to achieve a minimum tensile strength of 150,000 psi, making it appropriate for high-vibration and high-load joints found throughout construction equipment assemblies. When a fastener of the wrong grade or thread specification is used in these locations, the joint can lose clamping force over time, leading to component movement, accelerated wear, or structural failure at the connection point.
