Constructed from steel with a zinc-plated finish, it provides corrosion resistance suited for general mechanical and structural fastening applications. The nylon insert creates a prevailing-torque locking action without damaging mating threads. The nut measures 1-1\/16 inches across the flats and stands 7\/8 inches high. This fastener is installed by licensed mechanics, millwrights, pipefitters, and general tradespeople wherever a reliable, reusable locking nut is required.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is used in a wide range of residential, commercial, and light industrial applications. It is well suited for equipment assembly, bracket mounting, pipe hangers, structural connections, and any threaded assembly using 3\/4-16 UNF fasteners where vibration resistance is a priority. The zinc-plated finish makes it appropriate for interior and mildly corrosive environments. It conforms to Grade B dimensional standards for hex lock nuts with nylon inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-16 UNF thread for fine-thread applications requiring precise clamping\u003c\/li\u003e\n\u003cli\u003eGrade B classification meeting standard dimensional tolerances for hex lock nuts\u003c\/li\u003e\n\u003cli\u003eNylon insert provides prevailing-torque locking action without damaging mating threads\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1-1\/16 inch width across flats fits standard hex wrenches and sockets\u003c\/li\u003e\n\u003cli\u003eReusable design allows disassembly and reassembly without replacing the locking element under normal service conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or assembly hex lock nut for any 3\/4-16 UNF threaded fastener application requiring a Grade B nylon-insert prevailing-torque nut.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a standard hex socket or open-end wrench sized to 1-1\/16 inches across the flats. De-energize and lock out any equipment before servicing fasteners in live mechanical or electrical assemblies. Do not reuse nylon-insert lock nuts in high-cycle or safety-critical joints where the nylon locking element may have been degraded. Follow applicable mechanical and structural codes for fastener torque requirements based on grade, size, and joint type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut with Nylon Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MP34288\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712311394610,"sku":"MP34288","price":20.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/491250f2dff449b4ddd3c15519eb7c66.jpg?v=1788486095","url":"https:\/\/voomisupply.com\/products\/value-collection-mp34288-3-4-16-unf-hex-lock-nut-grade-b","provider":"Voomi Supply","version":"1.0","type":"link"}
