The 304 stainless steel is highly resistant to the corrosive chemicals found in modern pressure-treated wood (ACQ, CA, etc.). Unlike zinc-coated lag screws, stainless won’t prematurely rust or stain the wood.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Do I need to pre-drill before installing these 1\/4\" lag bolts?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: Yes, for best results and to prevent splitting, we recommend drilling a pilot hole using a 3\/16\" drill bit (or a bit slightly smaller than the bolt’s root diameter). Pre-drilling also makes driving easier and ensures the hex head sits flush.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Is the 7\/16\" wrench included? What tools do I need?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: The wrench is not included. You’ll need a standard 7\/16\" hex socket, combination wrench, or a nut driver. A cordless impact driver with a 7\/16\" hex socket makes quick work of driving these lag screws into wood.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: What’s the difference between a lag bolt and a regular wood screw?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: Lag bolts (or lag screws) have a thicker shank and a hex head, designed for heavy-duty structural applications where ordinary wood screws would shear. They’re ideal for deck ledgers, beam attachments, and framing. The partial thread pulls the top piece tight against the base material.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Can I use these outdoors in a coastal environment?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: Yes, 304 stainless steel offers good salt-spray resistance for most residential coastal applications. For constant immersion or extreme marine environments, 316 stainless would be better, but these 304 lag bolts will outperform standard galvanized screws by a wide margin.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"Default Title","offer_id":52247901339922,"sku":"KFCGBTST0151","price":21.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Main-01_489b7270-09af-42ff-81e0-52ec3818eeac.jpg?v=1778120407","url":"https:\/\/homediyer.com\/products\/70pcs-hex-head-1-4-20x2-lag-bolts-stainless-steel-wood-screws-hex-head-screws","provider":"HomeDIYer","version":"1.0","type":"link"}
