Chan Chin C. Window Fabrication Screws The range has been specifically designed for use in the fabrication of PVCu windows and is manufactured to meet all the recognised industry standards. A dedicated quality department applies rigorous checks to ensure conformance to specification for both screws and corrosion resistant plating. The in-house test facilities will check "pull-out" and "speed insertion" performance into individual profiles, as well as conducting "torque-testing" and "plating depth" testing on all batches of screws.
Self-drilling roofing screws are supplied with high performance anti-corrosive coatings and specialized materials that meet the performance requirements of AS 3566.1:2002 Self Drilling Screws for the Building Industry. Our roofing screws are designed with careful consideration of the relationship between drilling speed, stability and stripping torque to drilling performance. The Chan Chin C. roofing screw eliminates the cost of drilling and tapping holes as separate operations.
Self-tapping screws provide a useful and versatile range of fastenings. They are usually made from mild steel and, after the thread has been rolled, they are case-hardened to produce a hard surface at the thread with a tough core. Nickel or cadmium plating is the most common finish, but zinc, brass, copper and chromium platings are also used and plain steel and stainless steel screws are available. There are two basic kinds of self-tapping screw: thread-forming and thread-cutting. Thread-forming Designed for use in materials which are softer than the screw material, this type forms or squeezes the material into which it is inserted to produce the internal thread. Thread-cutting As the name implies, this type cuts a thread in the material into which it is inserted. It can be identified by a flute which runs a short way back from the point along the side of the thread.
Masonry Screws have a Phillips head and use advanced threadform technology that requires less torque. Chan Chin C. Masonry Screws have Blue Climaseal long life coating. The design allows for fast, easy installation and the screws are removable.

In addition the company has for 15 years been commissioning regular independent salt spray tests on the products at UKAS Testing Houses. Copies of certificates are available on request.
A chipboard screw or particleboard screw is a self tapping screw with a thin shaft and coarse threads. Chipboard is a made up of resin and wood dust or wood chips, so chipboard screws are made to grip this composite material and to resist withdrawing. The screws solidly fasten chipboard to chipboard or chipboard to other materials such as natural wood. Chipboard screws come in a variety of lengths and can be used to fasten chipboard in variety of applications. Average length chipboard screws are often used to join chipboard flooring to regular wood joists. Smaller screws may be used to fasten hinges to chipboard cabinetry. Very long screws may be used to butt chipboard to chipboard when making cabinets.
Chan Chin C. Deck screws are specially designed to eliminate the mushrooming and blemishes that can occur on composite materials. Since wood decks have many thin planks and must withstand harsh environmental conditions, deck screws are designed to accommodate the challenges of this application. Deck screws must resist corrosion, drive easily, and lay smoothly against the deck surface, called countersinking. For these reasons, many deck screws are self-countersinking, self-drilling, and coated with materials that won't rust.
Drywall is a type of building material made from gypsum and other minerals pressed between sheets of heavy paper. It is installed on walls and ceilings using a type of fastener known as a drywall screw. This fastener can be used to secure the drywall to either wood or metal framing members, and is designed to minimize dimpling on the face of the walls. Traditional nails tend to leave small holes in or divots in the drywall, and can even come loose over time. Drywall screws are threaded to grip both the drywall and the framing members tightly, and provide a much more secure and long-lasting installation over time.
