Manufactured from alloy steel with a black oxide finish, this screw resists corrosion and reduces light reflection in service environments. The fastener uses a 1\/16 inch hex drive and measures 5\/8 inch in length under the head. It is fully threaded to a 1-72 UNF specification, making it suited for fine-pitch connections in small mechanical assemblies, instrument enclosures, and precision equipment. Machinists, tool and die technicians, and equipment maintenance professionals are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in light-duty mechanical assemblies requiring a fine unified thread at the number-1 diameter. Applications include instrument panels, jigs, fixtures, electronic enclosures, and precision machine components where controlled clamping force and minimal fastener footprint are required. The black oxide coating provides mild corrosion protection and is appropriate for indoor or low-moisture environments. This SKU is sold individually but carries a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-72 UNF fully threaded profile for fine-pitch engagement in small-diameter tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch length under head provides adequate thread engagement in typical panel and fixture stock\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements for socket cap screws\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface corrosion and minimizes glare in precision assembly environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards for hex socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any tapped 1-72 UNF hole conforming to ASME\/ANSI B18.3 standards.

Verify that the mating tapped hole conforms to 1-72 UNF thread class before driving to avoid cross-threading in small-diameter threads. Do not exceed the recommended seating torque for a number-1 alloy steel fastener, and inspect the drive socket for wear before use to prevent stripping. A qualified machinist or mechanical technician should perform installation where thread engagement depth or clamping load is critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-72 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inch\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\/16 inch\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\u003eFastener Standard\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\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: 581030PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690736714034,"sku":"581030PR","price":7248.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ed5f5d1cbd8880f5485dcef78f7b7b6.jpg?v=1788274669","url":"https:\/\/voomisupply.com\/products\/value-collection-581030pr-hex-socket-cap-screw-1-72-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
