Using the Self-tapping Screws’ Tips.
A self-tapping screw forms its hole and taps its thread as it can be driven into various materials, also the tips and threads of self-tapping screws come in a vast array of patterns, depending on the application required.
Exactly, Self-tapping screws are ideal for applications where an item needs regular maintenance and need constant disassembly and reassembly which can be connected through wood and plastic before begin secured to a metal surface through the use of a drill to secure the screw in place. Self-tapping screws have any type of screw head design which are available in the market.
Here are the tips of using the self-tapping screws which help you to easily finish the project:-
The correct screw fit the right application: the first important must decide on the correct type of screw for the desired substrate to be fastened which is concerned with the materials required such as Material to place the screws into, Electric drill, Selection of screws. Then, consideration to choose the correct Screw from a selection the head type which helps it easier to keep your drill bits in place and prevent slipping and stripping such as flathead, Phillips, square, and torque.
Pay attention to a screw size. Choose a thickness that suite for the width of the material you’re placing the screw into, the same as the load which the screw able to be endurance, and check the screw length by choosing a length depends on the depth of the material you’re placing the screw into.
Safety: Be careful while using power tools. In the first step, you should mark the precise position where the screw will be used and ensure you have ample room to use a screwdriver or drill machine. Then, put on protective eyewear and the glove before you start to prevent any injury to your sight and hand.
Be sure the switch, power tools, or drilling are turned to the off position before you plug the tool into the electrical outlet.
Always keep the power tools in a safe place when you are not using them.
Drilling the Pilot Hole: After marking the precise position where the screw will be drilled. As usually it does not always necessary, but it is helpful for you to use the drill and drill bit to create a pilot hole in the material which you want to secure and ensures the screw will go in easily and will be positioned correctly. Also when you’re drilling into harder material such as sheet metal you need to drill a pilot hole in advance. For thicker metal, it may require more than one screw to drill through the surface. As the self-tapping screws come with a sharp, piercing tip or a flat. The sharp-tipped screws are designed for drilling their hole into softer materials such as wood and plastic so they don’t need a pilot hole.
However, you have to ensure to use a slightly smaller diameter of drill bit than the actual size of the self-tapping screw which you are using. Otherwise, if the drilled hole is too large, the screw threads won’t have anything to bite into as it turns in and unable to attach to.
Spinning the Tapping Screw: Focus on position the screw straight in line with the hole and turn it in. This allows the screw to be left in the hole as you pick up your screwdriver or drill machine. Using firm short movements, screw the self-tapping screw in place using a Phillips or flat head screwdriver or drill bit. Then, tighten the screw until it no longer turns easily and ensures that the self-tapping screw goes in straight, and do not over-tighten it as this could cause the head to strip. Be careful the torque while spinning the screw, not too high which will be the cause of screw broken.
Securing the Tapping Screw
Secure the tapping screw to the metal. Turn the screw in a clockwise direction until it is tightly attached. Be careful not to over tighten the screw. Over tightening could cause the screw to break or the metal to become damaged.
