It features a 5\/16-18 UNC thread size and a 1-1\/4 inch length under head, driven by a 1\/4 inch hex key. Constructed from 18-8 stainless steel, this fastener offers reliable corrosion resistance in wet, outdoor, or chemically exposed environments. The socket cap head design allows installation in recessed or tight-clearance areas where a standard hex bolt head would not fit. Licensed trades and industrial maintenance technicians commonly specify this fastener for equipment assembly, panel mounting, and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for residential and commercial mechanical applications where a compact, corrosion-resistant fastener is required. Typical use cases include HVAC equipment assembly, electrical enclosure mounting, plumbing fixture bracketing, and general equipment fabrication. The 18-8 stainless steel grade performs well in moderate-corrosion environments and is compatible with standard stainless hardware pairings. The UNC thread form is the most common coarse-thread standard in inch-based fastener applications across North American trade work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank provides maximum thread engagement along the full 1-1\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor service conditions\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex drive socket head allows installation in tight or recessed spaces\u003c\/li\u003e\n  \u003cli\u003eSocket cap head profile keeps the fastener low-profile against the mating surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 5\/16-18 UNC inch-series threaded fastener with a hex socket cap head.

Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading or galling, which is common with stainless steel fasteners. Apply an appropriate anti-seize compound when mating stainless to stainless to reduce the risk of thread galling. Power down or de-energize any equipment before performing fastener installation or removal on live assemblies.\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: 1-1\/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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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: 0.034 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: 198789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699243352370,"sku":"198789","price":15549.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19314b052805a17f5708ac70dac2442c.jpg?v=1788374032","url":"https:\/\/voomisupply.com\/products\/value-collection-198789-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
