Manufactured from Grade 8 steel with an uncoated finish, this fastener measures 7\/8-9 thread size with a 2.5-inch length under head. The UNC thread form and ASME B18.2.1 and SAE J429 compliance make it a reliable choice for structural and mechanical assemblies. This package contains 25 screws, suited for contractors, maintenance technicians, and tradespeople who need a dependable bulk supply of high-strength fasteners.\u003c\/p\u003e\u003cp\u003eThis screw is commonly used in industrial maintenance, heavy equipment assembly, structural steel connections, and general mechanical installations where Grade 8 strength is specified. The partially threaded shank provides a smooth bearing surface through thick materials before the thread engages, which is preferred in applications requiring precise clamping force. Suitable for use in both shop and field environments by mechanics, millwrights, and maintenance professionals working to ASME and SAE fastener standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank allows a smooth shank section for accurate alignment and clamping\u003c\/li\u003e\n\u003cli\u003e7\/8-9 UNC thread form for broad compatibility with standard inch-pattern hardware\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use as-is or with customer-applied coatings or thread compounds\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and material standards\u003c\/li\u003e\n\u003cli\u003eSold in a 25-piece package to support batch maintenance and production work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 7\/8-9 UNC inch-series nuts and tapped holes conforming to ASME B18.2.1 and SAE J429 specifications in structural and mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using the appropriate hex drive socket or wrench sized to the fastener head.
