This fastener features a 7\/16-20 UNF thread size, a 2.5-inch length under head, and a 3\/8-inch hex drive socket. The screw is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection on the fastener surface. It is partially threaded, which is typical for fasteners that must clamp two components together without thread engagement through the full grip length. Machinists, millwrights, and maintenance technicians are the primary installers of this type of fastener.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in industrial machinery, precision equipment mounts, jig and fixture construction, and general mechanical assembly where a fine-thread, high-strength alloy steel fastener is required. The 7\/16-20 UNF fine thread pitch provides tighter engagement per turn compared to coarse thread, making it well-suited for applications where vibration resistance and precise torque control matter. It is appropriate for both shop floor maintenance and OEM assembly environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-20 UNF fine thread for vibration-resistant clamping and precise preload control\u003c\/li\u003e\n\u003cli\u003e2.5-inch length under head with partial threading for full-shank grip in clearance holes\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards for high-strength socket head cap screws\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface corrosion in low-moisture environments and minimizes glare\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive compatible with standard hex keys and socket drive tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 hex socket cap screw suitable for any application requiring a 7\/16-20 UNF partially threaded fastener with a 3\/8-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or socket driver. Verify that the mating tapped hole or nut meets the 7\/16-20 UNF thread specification before installation. Clean threads and apply thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed the rated torque for the alloy steel grade; refer to your fastener torque specification chart for the applicable clamp load target.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 inches\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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\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: 0.12 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: 581526PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696420815154,"sku":"581526PR","price":1904.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4c77d05718c53809121df391f7aa7c8.jpg?v=1788342478","url":"https:\/\/voomisupply.com\/products\/value-collection-581526pr-hex-socket-cap-screw-7-16-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
