Manufactured from alloy steel with a black oxide finish, this screw measures 5\/16 inches under the head and is fully threaded from tip to head. The hex drive socket accepts a small hex key for controlled torque application in confined spaces. Black oxide coating provides moderate corrosion resistance and reduces light reflection in optical or instrument assemblies. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical property compliance. Machinists, instrument technicians, and precision assembly workers are the primary installers of this fastener class.\u003c\/p\u003e\n\u003cp\u003eThe 581002PR is suited for small-scale mechanical assemblies, instrument housings, electronics enclosures, optical equipment, and precision machine components where a 0-80 UNF thread form is specified. The fully threaded design maximizes thread engagement in thin material applications. The black oxide finish is appropriate for interior or low-moisture environments. This screw is sold individually per package with a minimum order quantity of 100 pieces, making it practical for production assembly and maintenance inventory replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0-80 UNF thread form for fine-pitch precision fastening\u003c\/li\u003e\n  \u003cli\u003eFully threaded body maximizes engagement in thin or shallow tapped holes\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for strength in small-diameter fastener applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for torque control in confined or recessed locations\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 0-80 UNF internally threaded hole with an ASME\/ANSI B18.3 hex socket cap screw. Typical fitment includes precision instruments, optical assemblies, and small mechanical devices with fine-thread tapped bores.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a correctly sized hex key or hex bit driver matched to the 0.05-inch drive socket. Verify that the mating tapped hole is clean, properly formed to 0-80 UNF specification, and free of debris before driving the screw. Do not exceed the torque capacity of the 0-80 thread form, as small-diameter fasteners are susceptible to thread stripping and shank breakage under excessive load. Black oxide finish provides limited corrosion protection and is not a substitute for plated or stainless finishes in wet or outdoor environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/16 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: 0.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece (100-piece minimum order)\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: 581002PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710824579378,"sku":"581002PR","price":2479.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66ee58316c94529294b7777f91fc5818.jpg?v=1788471033","url":"https:\/\/voomisupply.com\/products\/value-collection-581002pr-hex-socket-cap-screw-0-80-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
