Manufactured from Grade 8 steel with an uncoated finish, this fastener meets the dimensional and mechanical requirements of ASME B18.2.1 and SAE J429. The 5\/16-18 UNC thread and 1-1\/4 inch length under head make it a standard choice for applications requiring a reliable, high-tensile bolted joint. Each package contains 100 pieces, making it practical for production runs, field service kits, and shop stock.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in equipment manufacturing, machinery assembly, HVAC unit assembly, and general mechanical trade work where Grade 8 strength is specified. The fully threaded shank provides maximum thread engagement across the full length under head, which is useful in thin-material applications or where a nut and washer are used through the full grip length. Trade professionals including millwrights, HVAC technicians, and mechanical contractors commonly stock these for OEM-spec repairs and new installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fasteners\u003c\/li\u003e\n\u003cli\u003eFully threaded shank provides maximum thread engagement over the entire 1-1\/4 inch length under head\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread form for compatibility with standard unified coarse-thread nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use in dry interior environments or where a customer-applied coating is planned\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003cli\u003eSold in a 100-piece package for efficient shop stocking and field use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application specifying a 5\/16-18 UNC fully threaded Grade 8 fastener per ASME B18.2.1 and SAE J429.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or trade professional familiar with proper fastener torque procedures for Grade 8 hardware. Always consult the equipment manufacturer torque specification table for the applicable joint material and lubrication condition before tightening. Verify that mating threads are clean, undamaged, and of the correct thread class before assembly. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts not rated for the corresponding load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 99030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715935797554,"sku":"99030","price":27.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5424023d0443ff7917b233d240cae6e.jpg?v=1788519939","url":"https:\/\/voomisupply.com\/products\/value-collection-99030-hex-head-cap-screw-5-16-18-grade-8-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
