Hex lag screws, also known as hex bolts, are threaded fasteners that are used with wooden objects and workpieces. They differ from wood or self-drilling screws in that they have a hexagonal head, which makes them easier to drive using a socket wrench.
They are available in various materials to meet the needs of commercial, residential and industrial projects. Read on to learn more about these heavy-duty fasteners.
Hexagonal head
Hex lag screws have a hexagonal head that makes them easy to grip with wrenches and sockets. This makes them easier to install and remove than traditional fasteners with recessed heads, such as Phillips or slotted screw heads. The hexagonal head also distributes torque more evenly, reducing the risk of slippage or stripping.
Lag screws are heavy-duty fasteners used for lumber and thick metal applications. They are large and have coarse threads, which allow them to support more weight than a regular hex screw. They are often paired with a nut for added stability.
Hex lag screws can be made from various materials, including carbon steel and stainless steel. They can be treated for corrosion resistance, depending on the application and environment. Some hex lag bolts are even marked to indicate their grade, which is important for safety and reliability. These markings are typically located in the middle of the head and may have radial lines.
Coarse threading
Lag screws, also known as lag bolts, are some of the toughest fasteners out there. They’re used to connect heavy lumber or materials that will bear an intense load. They’re different from other types of screws, such as wood and self-drilling screws. The main difference is that they have course threading, which doesn’t encompass the entire length of the screw.
They have a hex head, which makes them easier to install and remove. They’re also easier to use in tight spaces because they have six access points. This makes them suitable for machinery projects and equipment assembly, as well as construction projects.
Lag screws are available in a variety of sizes and materials. Some are made of stainless steel, while others are made of low-carbon or high-carbon steel. In addition, they’re often coated with a zinc or galvanized finish. These coatings protect the screw against corrosion in harsh environments and climates. Some fasteners are also coated in silicon bronze for extra durability and corrosion resistance.
Length
The length of hex lag screws can be measured from the underside of the head to the pointed tip. These threaded fasteners are often used in wood construction projects and may be used it masonry applications as well. They are not considered to be bolts as they do not require a nut.
These heavy-duty hex headed screws can support much heavier loads than other types of screws. They are available in steel/zinc and stainless steel to resist corrosion and rust. Hex lag screws are easy to install using socket wrenches. They can also be used with lag shield anchors to prevent splitting of lumber.
Lag screw, or coach screws, are a type of thread-forming fastener that create their own mating threads during installation. They are usually installed into pre-drilled holes and can be driven in with a hex driver or ratchet. These screws are available in a variety of sizes, and can be installed in a wide range of materials and applications.
Material
Typically made from carbon steel, some lag screws are also available in stainless steel. This material provides an additional level of protection against rust and corrosion. Stainless steel is also resistant to abrasion and vibration.
Unlike most screws, hex lag screws are hot-forged, meaning they are heated and shaped using an upsetter. This process produces a semi-cone point, which makes them easier to install. The bolts also have a threaded area that extends from the point.
Lag screws are one of the toughest types of fasteners. They are used to fasten materials that are subjected to massive forces, such as lumber. They have a large, hexagonal head and coarse threads that can be driven with a socket wrench.
FMW Fasteners offers a variety of hex lag screws to meet your needs. These screws can be used in many applications, including mounting metal fixtures to wooden surfaces. Before installing them, it is important to ensure that the materials are properly aligned and to use clamps to hold them in place. It is also a good idea to predrill the hole with an attachment that has a smaller diameter than the hex lag screw.
