Built to Grade 9 steel specifications, it delivers greater tensile strength than the more common Grade 5 or Grade 8 fasteners, making it a reliable choice where load-bearing performance matters. The screw measures 1\/4-28 thread size with a 5\/8-inch length under head and is finished with Bowmalloy's Bowma-Guard zinc-plated clear chromate coating to resist corrosion in service environments. Full threading runs the entire length of the shank, providing maximum thread engagement in shallow or through-hole applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in precision mechanical assemblies, HVAC equipment mounting, electrical enclosure hardware, and general trade applications where a fine-thread, high-strength fastener is required. The 1\/4-28 fine thread pitch offers better vibration resistance and finer adjustment than coarse-thread equivalents, making it a common choice in applications subject to dynamic loads or frequent disassembly. It is sold in packages of 100 units, making it practical for service trucks, shop stock, or job-site replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction exceeds typical Grade 5 and Grade 8 strength ratings\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard zinc-plated clear chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 fine thread pitch improves vibration resistance over coarse-thread alternatives\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch length under head suits shallow fastening and tight clearance applications\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for bench stock and service inventory use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 1\/4-28 fine thread fastener with a 5\/8-inch grip length in Grade 9 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex head wrench or socket driver sized for a 1\/4-inch hex cap screw. Always de-energize and lock out equipment before accessing fastener locations on powered machinery. Do not mix thread classes or attempt to drive a fine-thread fastener into a coarse-thread tapped hole. Follow applicable equipment manufacturer torque specifications and relevant codes such as ASME or equipment-specific service manuals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 (Inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 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: Bowma-Guard Zinc-Plated Clear Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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\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: BOW36301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51960049762610,"sku":"BOW36301","price":95.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c4c871a2da735a4937ada8c21ea479e.jpg?v=1789946062","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36301-hex-head-cap-screw-1-4-28-x-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
