Apply to the mating threads, then assemble and torque as specified by the engine shop or vehicle manufacturer. This product offers practical, field-tested performance as a possible solution for keeping assemblies tight under challenging conditions. Individual results can vary with surface condition and operating environment.\u003c\/p\u003e\n\n\u003ch3\u003eAdditional considerations\u003c\/h3\u003e\n\u003cp\u003eLoctite 243 provides a balanced option for applications that require a medium-strength bond with the possibility of later disassembly. Its surface-insensitive properties support reliable bonding on slightly contaminated or oily surfaces, while the oil-tolerant formula helps maintain performance in the presence of engine lubricants. This makes it a practical choice for a range of common automotive fasteners and service tasks.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What fastener sizes does Loctite 243 cover?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Suitable for nuts and bolts from 1\/4 inch to 3\/4 inch (6 mm to 20 mm), delivering a medium-strength bond.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long does Loctite 243 take to cure?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Sets in about 10 minutes; full strength in 24 hours; temperature resistance up to 140°F.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Loctite","offers":[{"title":"Default Title","offer_id":42469704499285,"sku":"B005M1RI84","price":39.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/loctite-243-medium-strength-blue-threadlocker-bottle.jpg?v=1778104038","url":"https:\/\/plentytorque.co.uk\/products\/loctite-1330906-243-medium-strength-surface-insensitive-threadlocker","provider":"PlentyTorque","version":"1.0","type":"link"}
