Self Reversing Screw OEM Factory Custom - alibaba

Self Reversing Screw tapping screw material

The material can be divided into steel 1022A, stainless steel 410, stainless steel 304.

1, carbon Self Reversing Screw, 1022A, standard heat treatment steel can be used as drilling screw production materials, after heat treatment, surface hardness HV560-750, core hardness HV240-450. Ordinary surface treatment is easy to rust, has high hardness, low cost;

2, stainless iron drilling screw, 410, heat treatment, rust ability is better than carbon steel. Worse than stainless steel;

3, stainless Self Reversing Screw, 304, can not do heat treatment, rust ability, low hardness, high cost, can only drill aluminum plate, wood, plastic plate;

4, composite drilling screw, the drill is made of carbon steel production, thread, and head combined with 304 stainless steel production process.

The processing method of self - drilling self - tapping screw

Is 1, self-drilling screw with tapping screw, a screw, with a bit through a dedicated electric tool construction, drilling, tapping, fixed, a complete lock, self-drilling screw with tapping screw sheet is mainly used in some parts of connection and fixed, such as Choi steel connection with Choi steel, color steel plate, and purlin, wall beam connections, etc., its penetration is generally not more than 6 mm, not more than 12 mm;

2. Self Reversing Screw and tapping screws are often exposed outdoors and have strong corrosion resistance. The rubber sealing ring can ensure that the screw is impervious to water and has good corrosion resistance;

3. Self Reversing Screw and tapping screws are suitable for the use of wood materials, that is, wood screws we often say, are generally manual operation, because of manpower restrictions, these kinds of screws are generally very small, the scope of use is relatively narrow;

4, Self Reversing Screw with tapping screw is combined tap and bolts, the front is a tap, followed by a thread, in generally softer material, drilling and well can be directly turned into an empty, by tap-tapping screw, followed by a bolt thread for the matter, if the screw diameter is small, the material is soft, not even use a first punch, such as screws into the wood;

5. Self Reversing Screw and tapping screws are usually described by screw diameter series, screw number per inch length, and screw length. There are 10 and 12 screw diameter series, the corresponding screw diameter is 4.87mm and 5.43mm respectively; There are 14, 16, and 24 threads per inch. The more threads per inch, the better the self-drilling capability.
