Manufactured from alloy steel with a black oxide coating, this screw provides solid corrosion resistance in typical indoor and light-exposure environments. It features a 3\/8-24 UNF thread  -  a fine-pitch unified thread used where vibration resistance and precise load control are required. The drive is a 5\/16 inch hex socket, and the length under head is 1-1\/4 inches. The fastener is fully threaded along the shank. This screw meets ASME B18.3 and ASTM A574 dimensional and mechanical standards.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for applications where a flush or recessed fastener head is preferred over a hex-head bolt. Common uses include machine frames, bracket assemblies, HVAC equipment housings, pump and motor mounts, and general mechanical assemblies across residential and commercial service environments. The fine 3\/8-24 UNF thread pitch makes it a reliable choice in applications requiring tight clamp load control. Installation requires a standard 5\/16 inch hex key or Allen driver.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-24 UNF fine-thread profile for improved vibration resistance and precise torque control\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion protection for indoor and sheltered applications\u003c\/li\u003e\n\u003cli\u003eFully threaded shank along the 1-1\/4 inch length under head\u003c\/li\u003e\n\u003cli\u003e5\/16 inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fastener for mechanical assemblies requiring a 3\/8-24 UNF fully threaded hex socket cap screw meeting ASME B18.3 and ASTM A574 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 5\/16 inch hex key or Allen-head driver; ensure the drive tool seats fully in the socket to avoid cam-out. De-energize or shut down any equipment before fastener removal or replacement. Follow applicable torque specifications from the equipment manufacturer for the 3\/8-24 thread size. Inspect thread engagement in the receiving material to confirm adequate thread depth before applying final load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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: 5\/16 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 B18.3, ASTM A574\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: HOLO-KROME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743183372594,"sku":"73108","price":11258.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7d46c3b33b4791b165ed5d3ede795d6.jpg?v=1788843654","url":"https:\/\/voomisupply.com\/products\/holo-krome-73108-hex-socket-cap-screw-3-8-24-unf-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
