It features a 3\/8-24 UNF thread — a fine-pitch unified thread well-suited to applications requiring precise clamping force and resistance to vibration loosening. The screw measures 6 inches in length under the head and is partially threaded, allowing the unthreaded shank to bear shear loads in clearance-hole applications. Driving is done with a 5\/16-inch hex key. The alloy steel construction with a black oxide coating provides baseline corrosion resistance and reduces surface reflectivity. Licensed tradespeople, maintenance technicians, and machinists install this type of fastener across a wide range of equipment and fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in precision mechanical assemblies, machine frames, tooling fixtures, and equipment maintenance where a fine-thread socket head fastener is specified. The 3\/8-24 UNF thread pitch is commonly found in applications demanding tighter thread engagement than coarse-pitch alternatives allow, such as thin-walled components or vibration-prone environments. The 6-inch under-head length accommodates thicker or stacked material assemblies. Sold individually per package with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF fine-pitch thread for tight clamping and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head suits thick or multi-layer material stacks\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank handles shear load in clearance-hole applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex drive for standard hex key or socket installation\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 low surface reflectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or service fastener for any assembly specifying a 3\/8-24 UNF partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/16-inch hex key or matching socket driver. Always verify thread condition in the tapped hole before installation and use appropriate thread lubricant or anti-seize compound where specified by the equipment manufacturer. Ensure the mating material is rated for the clamping loads produced by an alloy steel fastener at the intended torque. Follow all applicable mechanical codes and equipment service documentation when replacing structural or load-bearing fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 6 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: 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 Coating\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\u003eWeight\u003c\/strong\u003e: 0.23 pounds\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: 10\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: 581506PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51713506607410,"sku":"581506PS","price":4072.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f8110ebb5c182e53f9784370b458f43.jpg?v=1788494191","url":"https:\/\/voomisupply.com\/products\/value-collection-581506ps-hex-socket-cap-screw-3-8-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
