This fully threaded screw features a hex socket drive, 1-72 UNF thread, and a 1-inch length under the head. Manufactured from alloy steel with a black oxide coating, it meets ANSI\/ASME B18.3 and ASTM F835 standards. The hardness rating of 36-43 HRC makes it suitable for demanding mechanical assemblies. Machinists, maintenance technicians, and assembly professionals install this fastener where flush or recessed head clearance is critical.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in precision instrument assemblies, light machinery, electronics enclosures, and mechanical sub-assemblies where a compact button head profile is required. The 1-72 UNF thread pitch is a fine-thread designation suited to thin-section or tapped-hole applications. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a common choice in optical, electronic, and industrial panel applications. A Thread Fit Class of 3A ensures close tolerancing for reliable mating with precision-tapped holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head, hex socket drive for low-profile installation with Allen wrench or hex key\u003c\/li\u003e\n  \u003cli\u003e1-72 UNF fully threaded, right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating for mild corrosion resistance and reduced reflectivity\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eThread Fit Class 3A for precision tolerance mating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension button socket cap screw per ANSI\/ASME B18.3 for use in any tapped hole or mating nut conforming to 1-72 UNF specifications with a Thread Fit Class 2B or 3B internal thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a properly sized hex key or Allen driver to avoid rounding the socket. Ensure the mating tapped hole conforms to 1-72 UNF thread form and tolerance before installation. Do not exceed the recommended seating torque for the thread size and material combination — consult published torque tables for 1-72 alloy steel fasteners. Follow applicable ASME or facility-specific mechanical assembly procedures when torquing safety-critical connections.\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\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\u003eHead Height\u003c\/strong\u003e: 0.0390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 36-43 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 701012PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689376022834,"sku":"701012PR","price":400.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e487947fd2fca7b6bf49657999ef1405.jpg?v=1788258522","url":"https:\/\/voomisupply.com\/products\/value-collection-701012pr-button-socket-cap-screw-1-72","provider":"Voomi Supply","version":"1.0","type":"link"}
