The square section grips into the part being fixed (typically wood), preventing the bolt from turning when the nut is tightened. A rib neck Carriage Bolt has several longitudinal ribs instead of the square section, to grip into a metal part being fixed.\u003c\/p\u003e  \u003cp\u003eZinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrate’s surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.\u003c\/p\u003e\u003cp\u003eCarriage Bolt \u0026amp; Nut ZP M12 x 130 Bag 5\u003c\/p\u003e","brand":"ForgeFix","offers":[{"title":"Default Title","offer_id":54240720257369,"sku":"FORCB12130G-TOOL","price":6.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/9257\/2761\/files\/7249a1e9-7ae4-4ef2-8ace-3e6de821cf2f.jpg?v=1744473263","url":"https:\/\/towntools.co.uk\/products\/forgefix-carriage-bolt-nut-zp-m12-x-130mm-bag-5","provider":"Town Tools","version":"1.0","type":"link"}
