Description

Self drilling self tapping screw is suitable for wood material use, that is, we often say wood screw, generally manual operation, due to human constraints, this kind of screw is generally very small, the scope of use is relatively narrow;

Self-drilling screw with tapping screw is combine tap and bolts, the front is a tap, followed by a thread, in generally softer materials, 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 first punch, such as screws into the wood;
Usage: it is a kind of screw, mainly used for fixing color steel tile of steel structure, also can be used for fixing sheet of simple building. It cannot be used for metal-to-metal bonding. Material has iron, stainless steel two kinds.
Models: φ 4.2/ φ 4.8/ φ 5.5/ φ 6.3mm, the specific length can be negotiated according to requirements.
According to the different drill tail can be divided into: round head rice/cross/plum blossom, countersink head (flat head)/rice/cross/plum blossom, hexagonal hua Si, round head Hua Si (large flat head), horn head

• self-drilling screw DIN 7504K hexagonal washer head, has a special drill point that allows drilling thickness sheets depending on the screw diameter from 2 mm ( screw diameter 3,5) up to 6 mm (screw diameter 6,3). Available in box and blister to meet any consumer need.

• DIN7504K, DIN7504L
  Ind Hex Washer head Self Drilling Screw is one of the most popular item among all the kinds and it is also widely applied.
