Grade 9 alloy steel delivers higher tensile strength than standard Grade 5 or Grade 8 fasteners, making this screw appropriate for demanding structural and mechanical assemblies. The clear chromate coating provides corrosion resistance in moderate-exposure environments. This fastener is installed by electricians, HVAC technicians, plumbers, and general mechanical contractors wherever a high-strength inch-series hex cap screw is specified.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial equipment, HVAC equipment frames, electrical enclosure assemblies, and general mechanical fabrication requiring a high-strength 1\/4-20 fastener. The partial threading provides a shank section that resists shear loads, making it preferable over fully threaded screws in applications where bolt shear strength matters alongside clamping load. It follows standard inch-series dimensional conventions and is compatible with 1\/4-20 nuts and tapped holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for higher tensile strength compared to standard Grade 5 or Grade 8\u003c\/li\u003e\n  \u003cli\u003eZinc-plated clear chromate finish for corrosion resistance in moderate-exposure conditions\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides improved shear load resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form follows standard inch-series fastener dimensions\u003c\/li\u003e\n  \u003cli\u003e2.5 inches length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series replacement or service fastener for assemblies requiring a 1\/4-20 hex head cap screw with a 2.5-inch grip length in Grade 9 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex wrench or socket driver sized for a 1\/4-20 hex head cap screw. De-energize and lock out any equipment before replacing or tightening fasteners on electrical enclosures or mechanical assemblies per OSHA lockout\/tagout requirements. Do not substitute a lower-grade fastener if Grade 9 is specified, as tensile and proof load ratings differ significantly. Inspect threads and mating tapped holes for damage before installation to ensure full thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 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: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 36010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52071558480178,"sku":"36010","price":79.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c10b453787b361d40fc19c28275c373_a5ffadf7-51fc-485e-8c30-8fb02f371bcd.jpg?v=1790049157","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36010-hex-head-cap-screw-1-4-20-x-2-5-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
