Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this fastener uses an internal nylon collar to create prevailing torque on the mating thread, maintaining clamp load without secondary locking hardware. The thread is #5-40 UNC, right-hand direction, with a 0.125 inch height and 0.25 inch width across flats. It is a standard inch-measurement fastener suited to light-to-medium duty mechanical assemblies across a wide range of trades and fabrication applications.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is appropriate for use in residential and light commercial mechanical assemblies where vibration resistance is needed without the bulk of flange or prevailing-torque metal-collar nuts. Typical install scenarios include equipment mounting brackets, sheet metal assemblies, HVAC component hardware, electrical enclosure fastening, and general plumbing fixture attachment. The zinc finish offers surface protection in dry or mildly humid interior environments. Installation requires a standard 0.25 inch hex wrench or socket.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style provides prevailing torque without additional locking hardware\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for standard-duty mechanical applications\u003c\/li\u003e\n  \u003cli\u003eZinc finish provides basic corrosion resistance in interior environments\u003c\/li\u003e\n  \u003cli\u003e#5-40 UNC thread for compatibility with standard inch-series fastener systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction per UNC fastener standard\u003c\/li\u003e\n  \u003cli\u003eCompact 0.125 inch height suits low-profile and tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex lock nut for any application using #5-40 UNC right-hand threaded fasteners in inch-measurement assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove using hand tools appropriate for a 0.25 inch hex flat, such as a standard open-end wrench or socket driver. Power down or de-energize any associated equipment before servicing fasteners on electrical enclosures or mechanical assemblies. The nylon insert is single-use by design — once fully seated and removed, the locking torque of the insert is reduced and the nut should be replaced. Follow applicable mechanical or electrical codes for fastener torque requirements specific to the assembly being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: #5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.243 to 0.251 inches (1\/4 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 0.268 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 305101PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692567363890,"sku":"305101PR","price":1721.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c390aabb5b2e1de518dee7387760605.jpg?v=1788299440","url":"https:\/\/voomisupply.com\/products\/value-collection-305101pr-hex-lock-nut-5-40-nylon-insert-grade-2","provider":"Voomi Supply","version":"1.0","type":"link"}
