In the entire fastener industry, fiberboard nails are as important as drywall screws and have a huge sales volume. They are widely used in furniture manufacturing and other industries, but their use in the DIY market is still very limited. At present, domestic consumers purchase this variety in building material supermarkets, mainly for installation of guide rails, hinges (such as 3.5*16, etc.), fish-style expansion installations (such as 4*40, etc.), and replacement of wood screws for furniture, cabinets, etc. . Fiberboard screws with better quality claws and cut tails are improved products of ordinary fiberboard screws. It is mainly optimized from the design of the thread to pursue higher drilling speed and solve the problem of easy cracking when used on hard wood. The problem is high technical content.
Fiberboard nails, the full name of fiberboard screws, are used instead of wood screws in many cases today. It is widely used and has a very large sales volume in China.
The appearance of fiberboard nails is generally black, with countersunk head, semi-sunk head, round head and other designs. The most commonly used in applications are 4mm, 5mm, 6mm.
Fiberboard nails have high technical content, and the nails are not easy to crack. In some hard woods, the problem of cracking at the nails can also be solved by modifying the thread design of ordinary fiberboard nails to make them fiberboard nails with claws and tails. Fiberboard nails are most suitable for wood materials and suitable for electric tool installation. Currently, they are mainly used in furniture manufacturing, cabinets and other fields.
The fiberboard nails produced by Fastener are worth choosing in terms of quality and price.
There are many types of countersunk head self-tapping screws. Generally, countersunk head and pan head are more commonly used. The surface treatment is generally galvanized white. However, its main application is to apply to thin metal plates, such as the connection between thin iron sheets and thin iron plates. The thread of the countersunk head self-tapping screw rises in a spiral, but the thread is smaller than that of the fiberboard nail, and the surface of the thread has a higher hardness. Therefore, in the thin metal plate connection, the internal thread can be tapped in the threaded bottom hole of the connected part to form a connection.
Therefore, from the design and application of countersunk head self-tapping screws, it can be known that self-tapping screws such as countersunk head self-tapping screws are not suitable for application on wood. The reasons are:
1: Self-tapping screws such as countersunk head self-tapping screws have shallow threads and cannot provide sufficient tension when used on wood such as particleboard. Iron objects have higher hardness, so they can provide sufficient tension.
2: When the screw is screwed in, the connected part will form a threaded hole. The shallower the thread, the smaller the deformation. For hard objects like iron, the smaller the deformation, the easier it is to screw in under the condition of sufficient tension.
And fiberboard screws In the entire fastener industry, this product is as important as drywall screws and has a huge sales volume. It is widely used in furniture manufacturing and other industries, but its use in the DIY market is still very limited. At present, domestic consumers purchase this variety in building material supermarkets, mainly for installation of guide rails, hinges (such as 3.5*16, etc.), fish-style expansion installations (such as 4*40, etc.), and replacement of wood screws for furniture, cabinets, etc. . Fiberboard screws with claws and cut tails are an improved product of ordinary fiberboard screws. It is mainly optimized from the design of the thread, pursues higher drilling speed, and solves the problem of easy cracking when used on hard wood. Technical content higher.
