It is distinguished from other bolts by its shallow mushroom head and that the shank cross-section of the bolt is circular for most of its length, as usual, but the portion immediately beneath the head is formed into a square section. This makes the bolt self-locking when placed through a square hole in a metal strap, or a round hole in most wood. This allows the fastener to be installed with only a single tool, a spanner or wrench, working from one side. The head of a carriage bolt is usually a shallow dome. The squared section is of the same size as the diameter of the bolt shank, with a plain unthreaded shank. Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them to bare timber, the squared section giving enough grip to prevent rotation. Carriage bolts are extensively used in security fixings, such as the Brenton Bolt where the bolt must only be removable from one side. The smooth domed head and square nut below prevent the carriage bolt from being unlocked from the insecure side.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003eFeatures \u0026amp; Specs\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eExterior Finish : Plain\u003c\/li\u003e\n\u003cli\u003eFastener Type : Carriage Bolt\u003c\/li\u003e\n\u003cli\u003eGrade Rating : Grade 5\u003c\/li\u003e\n\u003cli\u003eItem Hardness : Grade 5\u003c\/li\u003e\n\u003cli\u003eManufacturer Grade : Grade 5\u003c\/li\u003e\n\u003cli\u003eScrew Head Style : Round\u003c\/li\u003e\n\u003cli\u003eThread Size : 1\/4-20\u003c\/li\u003e\n\u003cli\u003eThread Style : Right Hand\u003c\/li\u003e\n\u003cli\u003eThread Type : Fully Threaded\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eItem details\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eASIN : B07FQ35M5N\u003c\/li\u003e\n\u003cli\u003eBrand : Newport Fasteners\u003c\/li\u003e\n\u003cli\u003eFastener Type : Carriage Bolt\u003c\/li\u003e\n\u003cli\u003eItem Weight : 48 Pounds\u003c\/li\u003e\n\u003cli\u003eManufacturer : Newport Fasteners\u003c\/li\u003e\n\u003cli\u003eNumber Of Items : 3500\u003c\/li\u003e\n\u003cli\u003ePart Number : 582117-3500\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eMaterials \u0026amp; Care\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eExterior Finish : Plain\u003c\/li\u003e\n\u003cli\u003eMaterial Type : Alloy Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eMeasurements\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eItem Weight : 48 Pounds\u003c\/li\u003e\n\u003cli\u003eSize Name : 1\/4'-20x5\/8',(FT)\u003c\/li\u003e\n\u003cli\u003eThread Coverage : Coarse\u003c\/li\u003e\n\u003cli\u003eThread Size : 1\/4-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Newport Fasteners","offers":[{"title":"Default Title","offer_id":45441883930647,"sku":"84260824XCXPI87E","price":62.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/9128\/9367\/files\/41TIm3to4fL_c0ac3fba-3e5a-452a-97df-8b29cf039087.jpg?v=1787741981","url":"https:\/\/morvenoria.com\/products\/carriage-bolts-grade-threaded-quantity-84260824xcxpi87e","provider":"Morvenoria","version":"1.0","type":"link"}
