Overview of the Process Screws

In any furniture mainly made of wood, screws will need equipment that has become a necessary and effective. Screw hardware is one very useful and effective, especially if the implementation is appropriate and well targeted.
Although the screws only as a small part of a furniture, will be very useful if we know how the screws are produced. On a visit to a factory equipment (screws, nails, nuts + bolts and other hardware for furniture, I had the opportunity to study the process of the production of furniture fittings.
Metal HardnessThe raw material comes from rolls screw with a steel rod Ø varies according to the size of the screw that will be produced. The following picture below shows the scrolls that had just come to the factory.


Here the main quality of the screw is determined. Iron has a certain hardness that can be arranged (at the time of production). For these types are usually mixed with steel screws. You will be able to 'feel' the quality of the raw material or hardness of metal screws that are used when installing the screws on the workpiece. The raw material is too soft screws will easily damaged at the head of the screw. But the raw material also should not screw over keris from raw materials 'tip screwdriver' as if the screw even harder, then the tip of a screwdriver will be more easily damaged.



Then roll the metal 'straightened' first using a special machine, and then cut to the length of the screw you want produced. In this process the metal form is grayish black, as there has been no sign of finishing layer on the metal.
Once formed small pieces, it will automatically set up the screw head as well as the manufacture of screw thread with a special machine. Up to here the process of formation is considered finished.
FinishingTo make it more durable screws, then need to be coated with a special material metal finishing. Metal finishing process is not the same as the process of finishing the wood. Screw rods are dissolved into a large vessel containing liquid specialty chemicals for metal finishing.Screws will be soaked for a certain time to get the necessary finishing layer.
After going through the finishing, screw inserted into a tool to clean up the sharp edges. The final stage is the internal quality control to select and remove the screws that do not meet quality standards.

TestingTo export quality furniture products and related directly with the children, the buyer will require furniture manufacturers to test the hardware (screws, nails, etc.) that will be used. The simplest test is a test that aims to determine how long the hardware will last against rust.But for the local production of furniture and furnishings in the room, the buyers are not too many of these requirements.

Tips when buying a screw:1. Check the hole for the screwdriver on the screw head, is deep enough for the tip of the screwdriver so that it can 'hold' with a good screwdriver.2. Heavier screws tend to have better quality.Color finishing on an assortment of screws, white or yellow gold. Both types of finishing it basically has the same durability, it's just a different process.3. Note the size of the 'threads / threaded' screw. For a softer type of wood you should use a larger thread size.4. Determine which type of screw head that you need.
