It features a 1-1\/4-7 UNC thread size and measures 5 inches in length under the head. Drive engagement is accomplished with a 7\/8-inch hex socket. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and durability in demanding environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming compliance with widely recognized fastener specifications. Maintenance technicians, millwrights, and equipment assemblers regularly use cap screws of this class in heavy-duty machinery and equipment builds.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for bolted joint applications that require a recessed-drive, high-tensile fastener. Partial threading allows for controlled clamping load and shank engagement in clearance holes. Typical use cases include machine frames, jig and fixture assembly, hydraulic component mounting, and structural mechanical connections where a flush or low-profile socket head is preferred over an external hex design. The black oxide coating provides mild corrosion protection and reduces light reflection in precision equipment environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread size for heavy-duty clamping applications\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head with partial threading for shank-to-clearance-hole engagement\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex socket drive for use with standard socket drivers and T-handle tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength cap screw requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex socket cap screw for industrial machinery, structural assemblies, and mechanical equipment requiring a 1-1\/4-7 UNC partially threaded fastener conforming to ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified millwrights, maintenance technicians, or mechanical assemblers familiar with high-strength fastener procedures. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench with the appropriate 7\/8-inch hex bit and follow the applicable engineering or equipment specification for torque requirements. Always de-energize and lock out equipment before servicing any fastened assembly per OSHA lockout\/tagout procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 7\/8 inches\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 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\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: -33721-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693299826994,"sku":"-33721-4","price":68.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de077c852eb6adaf5a48e2172f2381ec.jpg?v=1788310321","url":"https:\/\/voomisupply.com\/products\/value-collection-33721-4-hex-socket-cap-screw-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
