This fastener features a 1-1\/2-12 UNF thread size with a 4-inch length under head and is fully threaded for maximum thread engagement. Manufactured from alloy steel with a black oxide finish, it offers improved corrosion resistance and reduced light reflection in service environments. The 1-inch hex drive socket head accommodates standard hex keys and drive tools, making installation straightforward in confined or close-tolerance applications. It meets ASME\/ANSI B18.3 and ASTM A574 standards for socket head cap screws.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in machinery, tooling fixtures, hydraulic assemblies, and other industrial equipment where fine-thread engagement and high clamping force are required. The 1-1\/2-12 UNF thread pitch is commonly specified in applications demanding precise torque control and resistance to vibration loosening. Maintenance technicians, millwrights, and mechanical assemblers typically install this fastener in production and field service settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-12 UNF fine thread for vibration resistance and precise torque control\u003c\/li\u003e\n  \u003cli\u003e4 inches length under head, fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003e1-inch hex drive socket compatible with standard hex keys and drive tools\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 socket head cap screw standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for industrial machinery, fixtures, and assemblies specifying 1-1\/2-12 UNF hex socket cap screws per ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, mechanical assemblers, or maintenance technicians using a calibrated torque wrench and a 1-inch hex key or socket drive. Ensure mating threads are clean and free of debris before installation. De-energize and lock out equipment per OSHA lockout\/tagout procedures before servicing fastened assemblies.
