Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this screw delivers elevated tensile and proof load ratings compared to standard-grade fasteners. It features a 3\/8-16 UNC thread size, a 1-3\/4-inch length under head, and meets ASME B18.2.1 dimensional standards. Machinists, millwrights, maintenance technicians, and general tradespeople rely on Grade 8 hardware where vibration resistance and joint clamping force are critical.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy equipment assembly, machinery mounting, structural steel connections, and similar applications where a high-strength inch-series fastener is required. The partial threading allows a smooth shank section to pass through clearance holes, improving shear resistance and alignment in bolted joints. This screw is sold individually with a minimum order quantity of 25 pieces, making it appropriate for both single-repair needs and small-batch production work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength and proof load performance\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and identification as a high-strength fastener\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance in clearance-hole applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread standard ensures broad compatibility with inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for applications requiring 3\/8-16 UNC inch-series hex head cap screws in Grade 8 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician using an appropriately sized hex wrench or socket. Always verify the mating tapped hole thread class and material before installation. De-energize, lock out, and tag out any equipment before disassembling bolted joints on powered machinery. Do not mix Grade 8 fasteners with lower-grade nuts or hardware without confirming the joint design allows it.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/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: Partially 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 Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D39057\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716249977138,"sku":"D39057","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a6b251ba54cf0c025d68f437d8a4b5f.jpg?v=1788523541","url":"https:\/\/voomisupply.com\/products\/value-collection-d39057-hex-head-cap-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
