For bolts that won’t budge and screws that won’t slip, browse Newport Fasteners’ huge inventory of durable, high-quality hardware and fixings. More details at https://www.newportfasteners.com/screws/lag-bolts.html

Whether you’re a contractor, builder, joiner, maintenance engineer, or just a DIY enthusiast, you can bulk order heavy-duty screws, bolts, and other fasteners from the company's extensive web store.

How Soon Will My Order Arrive?

If you’re based in the US, you’ll benefit from same-day shipping on virtually all products and can expect delivery to any North American location within one to three working days.

What's On Offer?

New additions to the inventory include uncoated, carbon steel lag coach screws – available in packs of 100. These screws are ASME B18.2.1 and SAE J429-compliant, providing long-lasting performance in both indoor and outdoor settings. Their versatility makes them a valuable addition to your toolkit for construction, woodworking, furniture assembly, or more casual DIY projects.

Newport Fastener's new lag screws have a carbon-rich steel core with a galvanized zinc exterior which makes it resistant to rust: the zinc layer blocks any oxygen or moisture from reaching and weakening the core.

“There are many benefits of using lag screws depending on the application,” a spokesperson explains. “These screws are a good choice because they can sustain enormous amounts of pressure and strain. Manufacturing and construction companies use lag screws for better performance because of the bigger size, girth, and design.”

What's The Size Range?

You can order this product in a range of standard thread sizes – from 5/16” to ¾ inches – and lengths from one inch to 2 and ¾ inches.

Other additions to the inventory include 5/16 x 4 Hex Lag Screws made from 18-8 Stainless Steel. This product is designed for outdoor applications and comes with an external hex drive system, hex head, and a self-drill point style.

A spokesperson explains, “These extremely sturdy fasteners are usually used to connect heavy lumber or other heavy materials bearing intense loads. These screws differ from normal wood, self-drilling, or sheet metal screws. They boast coarse threading to add extra strength and security to help hold things together.”

The above products are a small sample of Newport Fasteners’ vast inventory of over 100,000 SKUs that includes Brass, Alloy, Steel, Aluminum, and Nylon pieces. Since its inception, the company has become a reliable partner for the Marine, Solar, Electronics, Lighting, and Construction industries.
