Made from alloy steel with a black oxide coating, this fastener delivers solid corrosion resistance and hardness in the 36-43 HRC range. The low-profile button head keeps the fastener below or flush with surrounding material surfaces where clearance is limited. It is driven with a 3\/16-inch hex socket and conforms to ANSI\/ASME B18.3 and ASTM F835 standards. Machinists, fabricators, and maintenance technicians are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light to medium-duty mechanical assemblies where a low-profile head is required and UNF thread engagement is preferred. The 5\/16-24 UNF thread standard provides finer thread pitch than UNC equivalents, making it a common choice for applications requiring controlled torque and vibration resistance. The black oxide finish blends into dark-colored housings and reduces light reflection in optical or precision equipment environments. This screw is sold in minimum order quantities of 100.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-24 UNF thread for fine-pitch engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness rating\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and low-reflectance finish\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head design for clearance-critical installations\u003c\/li\u003e\n  \u003cli\u003eDriven by 3\/16-inch hex socket — standard Allen key compatible\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the shank length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF button socket cap screw for use in mechanical assemblies, fixtures, and equipment requiring a 5\/16-24 thread and low-profile head geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 3\/16-inch hex key or socket driver. Ensure the mating threaded hole meets the Class 3A thread fit tolerance before installation. Apply thread-locking compound if the assembly is subject to vibration. Do not exceed the rated torque range for the alloy steel grade — consult the applicable ASME standard for torque specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.1660 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\/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\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\u003eWeight\u003c\/strong\u003e: 0.013 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 201145PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699593281842,"sku":"201145PR","price":1941.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5bf7914c891df54acc09e7149949d8e.jpg?v=1788377931","url":"https:\/\/voomisupply.com\/products\/value-collection-201145pr-button-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
