Featuring a 3\/8-24 UNF thread and a 3.5-inch length under head, this screw is partially threaded, making it well suited for applications that require a smooth shank section for precise fit in close-tolerance assemblies. Manufactured to ASME B18.2.1 and SAE J429 standards, it delivers the tensile strength and dimensional consistency required in demanding mechanical, industrial, and trade installations. It is installed by mechanics, millwrights, and trade professionals working in HVAC, plumbing, electrical, and general industrial assembly.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used wherever a fine-thread, high-strength fastener is required in inch-dimensioned assemblies. The 3\/8-24 UNF thread pitch provides greater thread engagement strength compared to coarse-thread equivalents, making it a preferred choice for applications subject to vibration or dynamic loading. Typical install scenarios include equipment mounting, bracket assembly, machinery fabrication, and structural connections in both residential and light commercial trade settings. The partial threading allows the unthreaded shank to bear shear loads more effectively than a fully threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and hardness\u003c\/li\u003e\n  \u003cli\u003e3\/8-24 UNF fine thread for superior thread engagement in vibration-prone assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows smooth shank section to carry shear loads\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head accommodates deeper fastening requirements\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in mechanical assemblies, equipment frames, and structural connections requiring a 3\/8-24 UNF Grade 8 partially threaded fastener per ASME B18.2.1 and SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified trade professionals using a properly sized hex socket or open-end wrench. Always verify thread engagement depth and ensure mating tapped holes or nuts meet Grade 8 or equivalent strength requirements. Do not mix inch UNF fasteners with metric or UNC threaded hardware.
