Position the screw straight in line with the hole and turn it in, one or two turns, by hand. 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.
How do you use a self tapping screwdriver?
You can insert self-tapping screws with either a hand-held or electric screwdriver. Before you use self-tapping screws, it's helpful, although not mandatory, to drill a pilot hole through the material. This ensures the screw will go in easily and will be positioned correctly.
Can you use self-tapping screws to drill through Metal?
For thicker metal, it may require more than one screw to drill through the surface. To save time and labor, you can use self-drilling self-tapping screws to drill into metal. Although these screws are more expensive, they're capable of drilling and fastening in one step. What is a self-tapping screw used for?

Do you need a pilot hole for self tapping screws?
Before you use self-tapping screws, it's helpful, although not mandatory, to drill a pilot hole through the material. This ensures the screw will go in easily and will be positioned correctly. Make sure to use a smaller drill bit than the self-tapping screw itself when drilling the pilot hole.

Do you need to pre drill sheet metal screws?
Standard vs Self-Tapping Sheet Metal Screws With the former, you'll have to drill a pilot hole into the sheet metal before installing the screw. With the latter, you don't have to drill a pilot hole prior to installation. Self-tapping sheet metal screws can be driven into sheet metal without the use of a pilot hole.
Do I need a pilot hole for self-drilling screws?
Self-drilling screws do not require a pilot hole, which accelerates installation time and lowers the cost and need of additional drill bits. This extra functionality and cost saving feature makes self-drilling screws the clear choice for metal building construction.
Do I need a drill for self-drilling screws?
Do you need a drill for self-tapping screws? No, self-tapping screws can simply be inserted with either a screwdriver. However, it's better to drill a small pilot hole before the you drill the screw.
What's the difference between self-tapping and self-drilling screws?
Self-Tapping – a screw for securing thinner sheet metals and other substrates that cuts its own thread, but usually requires a predrilled or pre-punched hole. Self-Drilling – a screw that can, well, self-drill through various gauges of metal materials without predrilling.
What type of screws do you use for sheet metal?
There are two basic types of sheet metal screws, self-tapping screws and self-drilling screws. Self-tapping screws have a sharp tip that is designed to cut through metal, but the metal must be pre-drilled before these screws can be used.
Do you need special drill bits for metal?
No Fancy Drill Bits for Metal Required Almost any general-purpose twist bit will do a decent job of drilling holes in metal. In fact, most drill bits for metal are manufactured to drill through a variety of materials, including wood and plastic.
What is a common use for self starting sheet metal screws?
Self-tapping screws also work for surfaces where you can't secure the rear end with a nut. Common applications include fastening aluminum sections, attaching metal brackets onto wood, or inserting screws into plastic housings.
Do sheet metal screws need washers?
Hex washer: A hex washer is a secondary name used for sheet metal screws. Like the hex, it has a hexagonal head, but it also has a washer to secure the screw's shaft to the material.
How do self drilling screws work?
Point Wings are used on some screws that fasten thicker materials, such as wood, to metal. The wings enlarge the hole in the fastened material, allowing the threads to pass through without contacting the fastened material.
How do you drill a hole in metal?
Drill at a Slow Speed In general, it's a good idea to drill through metal using as slow a speed as possible using a drill bit for metal. Hard metals like steel and larger drill bits require even slower speeds. With a small twist bit (1/16 in. to 3/16 in.), you can drill through most metals at 3,000 rpm.
Do you need special drill bits for metal?
Regular drill bits can't cut through steel, so you need a heavy-duty, hard drill bit to do the job. There are two types of drill bits that you can count on for metalworking projects: titanium and cobalt. Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating.
Self-Tapping Screws
Self-tapping screws allow you to dig into wood or softer materials without pre-drilling holes with the drill. This saves a lot of time, but it doesn't help you to get through that tough initial exterior layer of sheet metal. So it would be best if you drilled holes in the sheet metal, but not the wood.
Self-Drilling Screws
The self-drilling screws, on the other hand, can go in through the sheet metal and the wood. Self-drilling screws are typically self-tapping screws, but self-tapping screws are not necessarily self-drilling screws. Get the picture?
What is a self drilling screw?
Self Drilling Screws are used primarily when fastening into steel or other metals, and are typically used to join materials like sheet metal. Self Drilling Screws are primarily made of harder metals, or treated to make the material harder. Typical materials include hardened Zinc Plated Steel, and 410 Stainless Steel.
What material is used for self drilling screws?
Typical materials include hardened Zinc Plated Steel, and 410 Stainless Steel. This is to ensure that the drill point is a harder metal than that into which the screw is being installed. 410 Stainless Steel is ideal for Self Drilling Screws because it maintains the corrosion resistant properties of standard 18-8 Stainless, ...
What size tek screws are used for steel?
The typical 25 to 16 gauge metal will require the use of a TEK 3, but 14 gauge and below will require TEK 4-5. This is why TEK 5 screws are used for fastening into structural steel. As a general rule of thumb, the higher the TEK number (the longer the drill point), the thicker the metal.
What is a self tapping screw?
Self-tapping screws come with a sharp, piercing tip or a flat, blunt tip. The sharp-tipped screws are designed for drilling their own hole into softer materials such as wood and plastic so they don't need a pilot hole. The advantage of the flat-tipped screw is that it won't get stuck in the material and break off.
What is a hand held screwdriver?
A simple hand-held screwdriver can be used to drill a self-tapping screw.
Can you drill a hole in sheet metal?
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. To save time and labor, you can use self-drilling self-tapping screws to drill into metal.
