Grade 8 steel offers high tensile strength suited for demanding fastener applications. A zinc-plated finish provides corrosion resistance in general-purpose environments. This fastener meets ASTM A354 BD and MIL-HDBK-57 standards, making it appropriate for structural, mechanical, and industrial assembly work performed by maintenance technicians, millwrights, pipefitters, and general tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in residential and commercial mechanical assemblies where a high-strength, UNC-threaded fastener is required. Typical applications include equipment mounting, bracket attachment, and structural joint assembly across HVAC, plumbing, electrical, and general industrial installations. The 5\/16-18 thread size is a common standard in trade applications, and the 1-3\/8 inch under-head length accommodates moderate stack thicknesses in panel and frame work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad tool and hardware compatibility\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in general-purpose use\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A354 BD and MIL-HDBK-57 standards\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex key size for standard wrench and socket drive installation\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hex head cap screw suitable for use in any application requiring a 5\/16-18 x 1-3\/8 inch Grade 8 fastener conforming to ASTM A354 BD or MIL-HDBK-57 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2 inch wrench or socket driver.
