Built from Grade 9 alloy steel, this fastener delivers superior tensile strength compared to standard Grade 5 or Grade 8 hardware, making it a reliable choice where load demands are high. The 5\/16-18 thread size paired with a 1-inch length under the head suits a wide range of clamping and bolting tasks. A zinc-plated clear chromate finish provides corrosion resistance in moderately exposed environments. Licensed trades and maintenance professionals reach for this grade when critical joint integrity is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in mechanical equipment assemblies, HVAC equipment mounting, electrical enclosure hardware, and general industrial fabrication. The 5\/16-18 UNC thread pattern is one of the most common inch-series coarse thread sizes, making it compatible with a broad range of tapped holes, nuts, and threaded inserts found across commercial and light industrial equipment. Fully threaded construction allows maximum thread engagement even in thinner material sections, reducing the risk of fastener pull-through under load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement in thin or thick material\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread  -  one of the most widely used inch-series fastener sizes\u003c\/li\u003e\n  \u003cli\u003e1 inch length under head suits standard clamping and through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated clear chromate finish provides moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex head cap screw for any application requiring a 5\/16-18 x 1 inch fully threaded Grade 9 alloy steel fastener with a zinc-plated clear chromate finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or licensed tradesperson familiar with fastener grade requirements and torque specifications for the application. Always de-energize or lock out equipment before replacing or tightening hardware on live assemblies. Use a standard SAE hex socket or wrench sized for 5\/16-18 cap screws and apply torque per the joint designer's specification for Grade 9 hardware. Do not substitute a lower-grade fastener in applications where Grade 9 strength is specified.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Clear Zinc Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51972261904690,"sku":"36029","price":76.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c10b453787b361d40fc19c28275c373.jpg?v=1789965213","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36029-hex-head-cap-screw-5-16-18-x-1-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
