or lag screws
are considered as one of the most robust fasteners you can get in the market today. They have a highly durable construction, which makes them ideal for connecting components with an intense load. Lag screws are different from sheet metal screws; they have a larger size and thicker width. Lag screws can have hex heads too, which require using a nut driver.
Installing lag screws require proper alignment of all materials. Using a clamp can help in securing the components in place. Once in position, you should then drill a hole all the way through. The hole is where you will insert the screw.
