应用中，纤维板钉与自攻钉的都较多地应用在家具领域，但因纤维板钉和沉头自攻螺丝非常的相似，常有人将两者混淆。 In the application of fasteners , fiberboard nails and self-tapping screws are mostly used in the field of furniture, but because fiberboard nails and countersunk head self-tapping screws are very similar, some people often confuse the two. Although fiberboard nails and countersunk head self-tapping screws are both types of self-tapping screws, there are still differences between the two. Let me briefly explain it for everyone!
Fiberboard nails, full name fiberboard screws, are now used instead of wood screws in many cases. Their applications are very wide and their sales in China are very large.
The appearance of fiberboard nails is generally silver, with countersinks, semi-sinks, round heads, etc. The threads are spirally rising in a single line, generally full teeth, with specifications of 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 6mm. The most commonly used in applications are 4mm, 5mm, 6mm.
Fiberboard nails have a high technical content, and the nails are not easy to crack. The problem of cracks in the staples in some hard wood can also be solved by modifying the thread design of ordinary fiberboard nails to make them claw-cut fiberboard nails. Fiberboard nails are most suitable for wood materials and suitable for power tool installation. At present, they are mainly used in furniture manufacturing, cabinets and other fields.
所生产的纤维板钉无论在质量还是价格方面，都是值得选择的。 The fiberboard nails produced by ingenious fasteners are worth choosing in terms of quality and price.
Countersunk head self-tapping screws. There are many types of heads. Generally countersunk heads and pan heads are more commonly used. The surface treatment is generally galvanized white and the color is slightly dim. There is a drill like a drill at the point. It is applied to wood, but its main purpose is to apply it to thin metal plates, such as the connection between thin iron plates and thin iron plates. The countersunk head tapping screw thread rises in a spiral, but the thread is smaller than the fiberboard nail, and the thread surface 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 member, thereby forming the connection.
Therefore, from the design and application of countersunk head tapping screws, it can be known that self tapping screws such as countersunk head tapping screws are not suitable for use on wood.
1: The thread of self-tapping screws such as countersunk head self-tapping screws is shallow. When used for wood such as particle board, it cannot provide sufficient tension. And 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. If a hard object such as iron has sufficient tension, the smaller the deformation, the easier it will be to screw in.
