Manufactured from alloy steel with a black oxide finish, this fastener measures 1 inch in length under the head and uses a 1\/16 inch hex drive. The 1-72 UNF thread designation indicates a fine-pitch unified national thread, well-suited for small-diameter, high-strength connections where vibration resistance and close thread engagement are critical. It is partially threaded, which helps maintain clamping force in a range of structural and mechanical assemblies. Installation is typically performed by machinists, mechanical assemblers, or maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis screw is commonly used in light-duty mechanical assemblies, precision instruments, electronics enclosures, and small-component fixtures where a fine-thread, small-diameter fastener is required. The black oxide coating provides mild corrosion resistance and reduces light reflection, making it a practical choice for both indoor mechanical and instrumentation environments. The hex socket drive allows installation with a standard hex key or Allen driver in confined spaces where a conventional screwdriver or wrench cannot fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-72 UNF fine-thread profile for high-thread engagement in small-diameter applications\u003c\/li\u003e\n\u003cli\u003e1 inch length under head with partial threading for secure clamping\u003c\/li\u003e\n\u003cli\u003e1\/16 inch hex socket drive for use in tight or recessed installations\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and a low-reflectance finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style replacement or stock fastener for any assembly specifying a 1-72 UNF hex socket cap screw with a 1 inch length under head and 1\/16 inch hex drive, per ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 1\/16 inch hex key or Allen driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Power down or de-energize any equipment before fastener installation or removal when working near electrical components. Follow applicable mechanical assembly standards and inspect thread engagement before final tightening. Do not substitute a metric hex key, as an improperly sized driver will damage the socket recess.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1 inch\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\u003eThreading\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\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: 0.05 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: 581034PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694816690482,"sku":"581034PR","price":8261.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/757a5c5677c82d35379ae04ace53d87c.jpg?v=1788328661","url":"https:\/\/voomisupply.com\/products\/value-collection-581034pr-hex-socket-cap-screw-1-72-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
