Manufactured from Grade 2 steel with a bright uncoated finish, this bolt carries a 5\/16-18 UNC thread and measures 5\/8 inches in length under the head. It meets ASTM A307 standards, making it suitable for low-carbon steel fastener applications across a wide range of trades. Sold in a box of 100, it is a practical stocking item for contractors, maintenance technicians, and fabricators who require consistent, spec-compliant fasteners in volume.\u003c\/p\u003e\n\u003cp\u003eThis bolt is appropriate for residential and light commercial construction, equipment assembly, HVAC equipment mounting, plumbing fixture support, and general mechanical work where ASTM A307 Grade 2 fasteners are specified. The 5\/16-18 UNC thread is one of the most common coarse-thread sizes in the inch fastener system, fitting standard hex nuts, lock nuts, and threaded inserts of the same designation. The uncoated finish suits indoor and dry-location applications or situations where a plated or coated finish is not required by the specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard hardware\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch length under head  -  fully threaded along the entire shank\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM A307 fastener standard\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  no added plating or coating\u003c\/li\u003e\n  \u003cli\u003eSold in a box of 100 for jobsite and shop stocking\u003c\/li\u003e\n  \u003cli\u003eInch measurement system  -  fits standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5\/16-18 UNC hex nuts, coupling nuts, and threaded inserts in applications where ASTM A307 Grade 2 uncoated steel fasteners are acceptable per the project specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard 1\/2 inch hex wrench or socket driver.
