It features a 7\/8-9 UNC thread size with a 2-3\/4 inch length under head and a 3\/4 inch hex drive. The screw is partially threaded, making it well suited for clamping applications where the unthreaded shank bears shear loads. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance in indoor and light-duty industrial environments. Machinists, maintenance technicians, and assembly professionals install this type of fastener where a flush or low-profile socket head is required.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in general industrial assembly, machinery maintenance, and structural fastening where a hex socket drive is preferred over external-drive fasteners. The partial threading allows precise clamping force distribution and is common in fixture work, press assemblies, and equipment frames. It conforms to ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, meeting dimensional and mechanical property requirements expected in industrial fastener applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-9 UNC thread for heavy-duty clamping applications\u003c\/li\u003e\n\u003cli\u003e2-3\/4 inch length under head with partial threading for shear-load bearing\u003c\/li\u003e\n\u003cli\u003e3\/4 inch hex socket drive for torque application with standard hex keys or socket tooling\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers moderate corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install hex socket cap screw for industrial machinery, fixtures, and structural assemblies requiring a 7\/8-9 UNC partially threaded fastener.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or maintenance technicians using a calibrated torque wrench and a properly sized 3\/4 inch hex key or socket bit. Verify thread engagement and hole depth before installation to avoid bottoming out. Follow applicable fastener torque guidelines per ASME standards for alloy steel socket cap screws.
