This fastener features a 5\/16-18 UNC thread size and measures 2.75 inches in length under the head. It is driven with a 7\/32-inch hex key and is partially threaded for controlled engagement. Manufactured from alloy steel and finished with a black oxide coating, it meets the ASTM A574 standard for high-strength socket cap screws. Installation is straightforward and suits a wide range of structural and equipment-assembly tasks.\u003c\/p\u003e\u003cp\u003eThis screw is suited for mechanical assemblies requiring a high-strength, compact fastener where a hex socket drive is preferred over a hex head. Common applications include machine frames, jigs, fixtures, equipment panels, and general fabrication work. The partially threaded shank allows for precise clamping force between mated components. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it appropriate for indoor industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread for standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003e2.75-inch length under head for deeper fastening reach\u003c\/li\u003e\n\u003cli\u003e7\/32-inch hex socket drive for reliable torque transfer with a hex key\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for controlled clamp load\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for any application requiring a 5\/16-18 UNC hex socket cap screw conforming to ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 7\/32-inch hex key or socket bit. Ensure the mating tapped hole is clean and free of debris before driving. Do not over-torque, as alloy steel cap screws require the torque value specified by the assembly or equipment manufacturer. De-energize and lock out any equipment before fastener replacement on live machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.75 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: 7\/32 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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 pounds\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: 307119PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67592845558066,"sku":"307119PR","price":489.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3d4393290d1151337a0e6cc1706718c_fc00f563-2ab4-4745-91bc-399d58e4755a.jpg?v=1790421984","url":"https:\/\/voomisupply.com\/products\/value-collection-307119pr-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
