It features a 5\/16-18 UNC thread size with full threading along its 1-1\/4 inch length under head. The screw is driven with a 1\/4 inch hex key and is manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and a clean, low-reflectance finish. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards. Machinists, maintenance technicians, fabricators, and millwrights commonly install this fastener type across a wide range of commercial and industrial settings.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general-purpose mechanical and structural fastening where a recessed drive head is required for flush or below-surface installation. The 5\/16-18 UNC coarse thread pattern offers good pull-out strength and resistance to loosening under vibration. The black oxide alloy steel construction makes it appropriate for interior or dry-environment assemblies. It is sold in multiples of 25 units minimum.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC coarse thread for strong engagement and vibration resistance\u003c\/li\u003e\n\u003cli\u003eFully threaded along the 1-1\/4 inch length under head\u003c\/li\u003e\n\u003cli\u003e1\/4 inch hex socket drive for precise torque application with standard hex keys or Allen drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides a clean finish with moderate corrosion resistance in dry environments\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw compatible with any 5\/16-18 UNC threaded hole requiring a 1\/4 inch hex drive fastener in alloy steel construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/4 inch hex key or Allen-head driver; ensure proper seating and alignment before applying torque. Power down and de-energize any equipment before accessing fastener locations on live machinery. Do not mix thread standards — confirm the receiving hole is machined for UNC threads before installation. Follow applicable industry torque guidelines for alloy steel socket cap screws of this thread class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\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\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\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: MP33620-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710442504498,"sku":"MP33620-1","price":19.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d41d45c57779317ffefeb3d1a02caac.jpg?v=1788467008","url":"https:\/\/voomisupply.com\/products\/value-collection-mp33620-1-hex-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
