It features a 1-8 thread size with a 2-1\/2 inch length under the head, manufactured from Grade 9 alloy steel. Grade 9 alloy steel delivers tensile strength above standard Grade 5 and Grade 8 hardware, making this fastener well suited for heavy-duty structural, mechanical, and equipment assembly work. The clear zinc chromate finish provides a base level of corrosion resistance. Sold in packages of 10, this screw is a direct fit for applications requiring inch-system, coarse-thread fasteners in demanding load-bearing environments.\u003c\/p\u003e\u003cp\u003eThis cap screw is used across a range of commercial and industrial applications, including HVAC equipment mounting, mechanical equipment frames, structural steel assemblies, and general trade fabrication work. The 1-8 coarse thread pattern is the standard for this diameter in the inch fastener system, making it compatible with the widest range of nuts, inserts, and tapped holes at this size. Machinists, millwrights, HVAC technicians, and general contractors routinely specify Grade 9 alloy fasteners where elevated proof load and tensile strength are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 9 alloy steel construction for high tensile and proof load performance\u003c\/li\u003e\n\u003cli\u003eFully threaded shank along the full 2-1\/2 inch length under the head\u003c\/li\u003e\n\u003cli\u003e1-8 coarse thread in the inch measurement system\u003c\/li\u003e\n\u003cli\u003eClear zinc chromate finish for baseline corrosion protection\u003c\/li\u003e\n\u003cli\u003eHex head drive for use with standard hex wrenches and sockets\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 10 per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-system hex head cap screw for use with any 1-8 threaded nuts, tapped holes, or inserts requiring a Grade 9 alloy fastener in structural or mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified tradesperson using calibrated torque equipment appropriate for Grade 9 alloy fasteners at the 1-inch diameter. Always confirm thread engagement depth and verify that mating nuts or tapped holes are rated to match the fastener grade. De-energize and lock out any equipment before fastener replacement on mechanical systems. Follow applicable codes and equipment manufacturer torque specifications when installing structural or load-bearing fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 inches\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 36215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":67580789686578,"sku":"36215","price":127.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6024124ef0b2d44d41db1c649ffbaad3_43aa7316-cf2a-4a39-99d7-040e2841e6a6.jpg?v=1790397556","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36215-hex-head-cap-screw-grade-9-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
