It features a 1-64 UNC thread and a 3\/4-inch length under head, making it suited for tight-clearance assemblies where a standard external hex drive would not fit. The 5\/64-inch hex socket drive accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide finish, this screw provides structural strength and moderate corrosion resistance in controlled environments. Machinists, millwrights, and assembly technicians are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light mechanical assemblies, precision instruments, tooling fixtures, and small machine components where a low-profile, internally driven fastener is required. The 1-64 UNC thread is one of the smallest unified coarse thread sizes, making this part appropriate for fine assemblies in electronics enclosures, jigs, and fixtures. The black oxide coating blends with dark metal surfaces and provides mild lubricity during installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-64 UNC thread for precision small-fastener applications\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch length under head for adequate thread engagement in thin and medium-thickness materials\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch hex socket drive accepts standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement along the full length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 hex socket cap screw suitable for threaded holes and inserts sized for 1-64 UNC thread in metal assemblies, fixtures, and precision mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand using a 5\/64-inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not over-torque small-diameter screws of this size, as alloy steel fasteners at the 1-64 UNC scale are susceptible to shear failure if excessive force is applied. Apply a thread lubricant or anti-seize compound when installing into dissimilar metals to prevent galling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-64 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 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: 5\/64 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 Coating\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\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: 581025PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706726613298,"sku":"581025PR","price":1025.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7179989e42a98e364feb35066313b48.jpg?v=1788436316","url":"https:\/\/voomisupply.com\/products\/value-collection-581025pr-hex-socket-cap-screw-1-64-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
