This screw features a 1\/2-13 UNC thread size, a 2.5-inch length under head, and a 3\/8-inch hex drive. The alloy steel construction provides excellent tensile strength, and the Armor Coat finish delivers corrosion resistance suited for demanding environments. It is partially threaded, which is standard for load-bearing bolted joints where full-thread engagement is not required. Installation is performed with a 3\/8-inch hex key or Allen-type driver. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in a wide range of industrial and mechanical applications including equipment assembly, fixture fabrication, jig construction, and machine maintenance. The 1\/2-13 UNC coarse thread is well suited for general-purpose fastening in ferrous and non-ferrous materials where vibration resistance and thread engagement strength are priorities. Partial threading allows the unthreaded shank to act as a locating feature in through-hole applications. The Armor Coat finish makes this screw appropriate for use in moderately corrosive or outdoor service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for strong, vibration-resistant engagement\u003c\/li\u003e\n\u003cli\u003e2.5-inch length under head suits deeper clearance and through-hole applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eArmor Coat finish offers corrosion protection for industrial and outdoor use\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank supports accurate part location and load distribution\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 1\/2-13 UNC partially threaded fastener with a 3\/8-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or socket-head bit driver torqued to the fastener manufacturer or equipment OEM specification for 1\/2-inch alloy steel cap screws. De-energize and lock out all equipment before replacing or installing fasteners in mechanical assemblies per applicable OSHA lockout\/tagout procedures. Inspect mating threads for damage or contamination before installation. Do not use an impact driver without a torque-limiting device, as overtorque can damage the Armor Coat finish and thread engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 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: 3\/8 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 Coating\u003c\/strong\u003e: Armor Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3\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: 0.0018 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: ARMOR COAT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST235996\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMOR COAT","offers":[{"title":"Default Title","offer_id":67911303201074,"sku":"UST235996","price":6102.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b713819eaa4c48166b78fa747a38153_84507d09-f80e-4aa8-ade7-a1b5a7321451.jpg?v=1791208880","url":"https:\/\/voomisupply.com\/products\/armor-coat-ust235996-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
