It features a 1\/4-20 UNC thread and a 1-5\/8 inch length under the head, driven by a 3\/16 inch hex key. Constructed from alloy steel with a black oxide finish, it offers solid corrosion resistance for indoor and low-exposure outdoor use. Partially threaded shank provides clamping force in through-bolt configurations. Meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for precision and load-bearing fastening in professional trade and industrial settings.\u003c\/p\u003e\u003cp\u003eThis screw is suited for machinery maintenance, equipment assembly, and fabrication work where a recessed drive and controlled clamp load are required. The 1\/4-20 UNC thread is one of the most common unified coarse thread sizes in North American mechanical applications. Partially threaded geometry makes it well-suited for clamping two or more components together where the unthreaded shank spans the joint interface. Sold individually with a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard tapped holes and nuts\u003c\/li\u003e\n\u003cli\u003e1-5\/8 inch length under head with partial threading for effective clamping\u003c\/li\u003e\n\u003cli\u003e3\/16 inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meeting ASTM A574 for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\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 1\/4-20 UNC hex socket cap screw for use in any application requiring ASME\/ANSI B18.3 and ASTM A574 compliant fasteners with a 3\/16 inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, and general tradespeople using a 3\/16 inch hex key or Allen driver. Ensure the receiving thread is clean and properly tapped to 1\/4-20 UNC before installation. Apply thread lubricant or thread-locking compound as required by the application or applicable mechanical code. Never use an impact driver on socket cap screws without a rated socket adapter, as this can damage the drive recess.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\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: 581373PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703564894514,"sku":"581373PR","price":6398.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c52a6edbb0b35e32058fe4b0b0dd3c5.jpg?v=1788417373","url":"https:\/\/voomisupply.com\/products\/value-collection-581373pr-hex-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
