It features a 1\/4-20 UNC thread pattern and measures 1-3\/4 inches in length under the head. The 3\/16-inch hex drive socket accepts a standard hex key or Allen driver for installation. Constructed from alloy steel with a zinc-plated finish, this screw resists corrosion and delivers high tensile strength for demanding applications. It is partially threaded, which helps maintain clamping force in through-hole and tapped-hole configurations. Machinists, maintenance technicians, and mechanical contractors are the typical installers of this fastener type.\u003c\/p\u003e\u003cp\u003eThis socket cap screw suits a wide range of industrial, mechanical, and structural applications where a low-profile, high-strength fastener is required. The 1\/4-20 UNC thread is one of the most common inch-series thread sizes, making this screw compatible with standard tapped holes, threaded inserts, and hex nuts of the same specification. Typical use cases include equipment assembly, fixture fabrication, and machine maintenance across manufacturing and trade environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard inch-series tapped holes and hardware\u003c\/li\u003e\n\u003cli\u003e1-3\/4-inch length under head for adequate engagement in moderate-depth applications\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive accepts standard hex keys and ball-end drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile strength per ASTM A574\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers corrosion resistance for general-purpose use\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank maintains clamping force and alignment in bolted joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex socket cap screw conforming to ASME B18.8 and ASTM A574, suitable for use in any tapped hole or assembly requiring this thread size and drive type.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or Allen driver; a torque wrench with the appropriate hex bit is recommended for controlled tightening in precision assemblies. Always ensure the mating tapped hole or threaded insert matches the 1\/4-20 UNC thread specification before driving the fastener. De-energize and lock out any equipment being serviced before installing or removing fasteners in live mechanical systems. Follow applicable ASME or equipment manufacturer guidelines for fastener preload and inspection intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 872159PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716253876530,"sku":"872159PR","price":5676.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef6720c757834135ee8af4c7b0630447_f84ca416-f43c-4d85-9758-dda6b51ae784.jpg?v=1788523603","url":"https:\/\/voomisupply.com\/products\/value-collection-872159pr-1-4-20-socket-cap-screw-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
