The screw features a 5\/16-18 UNC thread and a 3-inch length under head, making it suitable for medium-depth fastening in structural and mechanical assemblies. The 1\/4-inch internal hex drive accepts a standard hex key or Allen wrench. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet, humid, or mildly corrosive environments. Machinists, millwrights, and general maintenance professionals use this style of cap screw across a wide range of industrial and commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in mechanical assemblies, equipment mounting, and fixture construction where a flush or recessed drive is preferred over an external hex head. The partial threading provides a smooth shank section that can act as a locating feature or bear shear loads in close-tolerance bores. Typical installation environments include manufacturing equipment, HVAC equipment frames, pump housings, and general industrial machinery. It is sold in a package quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard unified coarse-thread tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head accommodates medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank for shear-bearing and close-tolerance fit\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch internal hex drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet or humid environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any application requiring a 5\/16-18 UNC partially threaded socket head cap screw with a 3-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1\/4-inch hex key or socket driver. Always ensure the mating tapped hole is clean and free of debris before driving the fastener. De-energize and lock out any equipment before replacing fasteners on or near moving components. Avoid over-torquing stainless steel fasteners, as 18-8 material is susceptible to galling; use an appropriate anti-seize compound when driving into stainless or aluminum threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex (Internal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/4 inch\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 199726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691945361714,"sku":"199726","price":2737.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9de6a8ccbe041ac8656e8f347e312898.jpg?v=1788291289","url":"https:\/\/voomisupply.com\/products\/value-collection-199726-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
