What Can Concrete Screws Do for You?
Concrete Screws or masonry screws made of stainless steel and carbon steel are ideal for use in
concrete, brick or block base material. They have the following features:

 Commonly with corrosion coating.
 Tested for fire safety.
 Easy and fast to install: drill, drive, done.
 No plugs needed.
 Removable and adjustable.
 Suitable for concrete, brick, natural stone, etc.
 Different types of head designs and surface treatment for multiple applications.
 Can be used close to the edges.
Different Head Types
There are three kinds of head styles of concrete screws - flat head, pan head and slotted hex head.
Comparing the different kinds of screws, the flat head and pan head concrete screws can be flush
to material surface and look nice, and the slotted hex head ones are easier to drive in. So the
choice depends on the location where the screw is fastened.

2 Small packing 100/200/500/1000pcs/box, then in carton.
3 According to the customer's demand.
Customer's design and requirement are welcome.
Application
Concrete Screws are very utility and are ideal for use in fastening applications. These screws come
in various sizes and styles which are very easy and fast to install. Besides, concrete screws can be
removed without damaging the base materials after installing. These screws can also be installed
close to the edge.
Different lengths allow the screws to be used in many applications including: studs, plywood,
electrical boxes, and exterior insulation systems.
They can also be used for fixing window or door frames manufactured from wood, plastic or
metal to concrete, brick, hollow brick or man-made blocks.

4. Installation Steps
4 Measure the thickness of the material you will fasten to the concrete. Then choose a
screw that is 1 to 1.75 inch longer than the thickness of the material.
5 Choose a drill bit that is suitable for the screws. The diameter of the drill bit should be a
little smaller than the screws.
6 Measure the length of the screw. Then wrap the tape on the drill bit to mark the length of
the screw. The tape can avoid drilling too deep in the concrete.
7 Drill the hole until you reach the tape.
8 Clean out the excess material from the hole with a wire brush and a vacuum.
9 Set the material over the hole, and then screw the material into the concrete.

Self-tapping Screws - Perfect for Metal, Plastic and Wood Work
Self-tapping screws, mainly made of carbon steel or stainless steel, are widely used on plastics,
metal and wood materials. The best part in the use of self-tapping screws is that there is no need to
drill holes before they are used. The two basic types of self -tapping screws are thread-forming
screws and thread-cutting screws. The thread-forming screws are commonly used for plastic,
deforming the material as the screws enter. The thread-cutting screws are typically used for wood
and metal, removing some of the material and creating a threaded path for the screw.
Application
The tapping screws are used mostly on plastic, metal and wood material.
 mostly used in automobile industries, aircraft, shelving and tables made of metal.
 Commonly used for wood objects like decks and furniture.
 Widely used on construction like drywall and roof.
