Manufactured from Grade 9 alloy steel, it delivers tensile strength above standard Grade 8 hardware, making it a preferred choice where fatigue resistance and clamp load matter. The 7\/16-20 fine thread provides precise torque control and strong thread engagement in steel and aluminum components. A zinc-plated clear chromate finish adds corrosion resistance for moderate-exposure environments. Licensed tradespeople, millwrights, and field technicians install this fastener where reliable, high-torque connections are required.\u003c\/p\u003e\n\u003cp\u003eThis screw suits a wide range of trade applications including HVAC equipment mounting, mechanical power transmission assemblies, pump and motor brackets, and heavy equipment repairs. The fine-thread 7\/16-20 pitch is especially effective in thin-walled tapped holes and applications requiring vibration resistance. The 3\/4-inch length under head makes it appropriate for shallow through-hole and tapped-hole installations in moderate-thickness material. It is sold in packages of 50 units, supporting both single-job use and bench-stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction exceeds Grade 8 minimum tensile requirements for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 fine thread provides tight thread engagement and improved vibration resistance compared to coarse thread\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the full 3\/4-inch working length\u003c\/li\u003e\n  \u003cli\u003eZinc-plated clear chromate finish provides moderate corrosion protection in indoor and light-exposure environments\u003c\/li\u003e\n  \u003cli\u003eStandard hex head accepts common 5\/8-inch wrench or socket tooling\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 50, suitable for bench stock or single-trade applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-strength inch-series hex head cap screw for use in any application requiring a 7\/16-20 fine-thread fastener with a 3\/4-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople following applicable mechanical codes and equipment manufacturer torque specifications. Always ensure the mating tapped hole or nut matches the 7\/16-20 fine-thread specification before assembly. De-energize and lock out equipment before replacing fasteners on live mechanical systems. Do not mix Grade 9 hardware with lower-grade nuts or threaded inserts, as mismatched hardware grades can reduce joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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\u003c\/strong\u003e: Zinc-Plated Clear Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 36377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51971395060018,"sku":"36377","price":66.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6024124ef0b2d44d41db1c649ffbaad3_7ff26a65-239b-4c53-882d-8fd132dc1ae9.jpg?v=1789956797","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36377-hex-head-cap-screw-7-16-20-x-3-4-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
