The distinctive conical top features distorted or deflected threads that create a frictional locking action against the mating bolt without the use of a nylon insert -- making it suitable for higher-temperature environments where nylon insert nuts are not appropriate. Also known as a Conelock, Stover, Crownlock, or Autolock nut, the Toplock style is widely used in agricultural equipment, automotive, and industrial assembly applications.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e  \u003cli\u003eThread Size: 1\/4-20 UNC (1\/4 inch nominal diameter, 20 threads per inch)\u003c\/li\u003e  \u003cli\u003eType: All-metal prevailing torque hex locknut\u003c\/li\u003e  \u003cli\u003eLocking Mechanism: Distorted\/deflected top threads (conical top)\u003c\/li\u003e  \u003cli\u003eInstallation: One-way -- conical top up\u003c\/li\u003e  \u003cli\u003eThread Direction: Standard right-hand\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNew aftermarket replacement part - not remanufactured, not used.\u003c\/p\u003e","brand":"Reliable Aftermarket Parts, Inc® -OD","offers":[{"title":"Default Title","offer_id":41372960653395,"sku":"A-80A8-AI","price":7.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/RAP_ComingSoon_Tractor_31ef1900-b79e-4ed7-bc7c-7318fbd7a9d7.jpg?v=1757747704","url":"https:\/\/www.reliableaftermarketparts.co.uk\/products\/a-80a8-ai-nut-1-4-20-toplock","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
