Yellow zinc torx drive double countersunk head wood chipboard screw
Chipboard screws, also named particleboard screws, are self-tapping screws with thin shafts and coarse threads. They are made of carbon steel or stainless steel and then galvanized. Chipboard screws of different lengths can be used in a variety of applications. They are created to fasten low, medium and high density chipboard. Many chipboard screws are self-tapping, so there is no need to drill holes in advance.
* Material:Made of carbon steel C1022A to make the Chipboard Screw have stronger strength. Adopt high-strength rolling arm, small gap, mute, wear-resistant, uniform force.
* CSK countersunk head: The double countersunk head could help to increase head strength. The flat head helps the chipboard screw keep same level with the material.
* Groove:Most of the Chipboard Screws use the Pozi or Phillips’ The cross groove help s not slip when use the screw gun.
* Sharp Point: The Chipboard Screws with sharp point which make them easier to stab the screw into material without a pilot drill hole. The Type 17 point make the screw sharper to use.
* Surface Treatment:After a zinc plating and heat treated to make the Chipboard Screws resist corrosion and harder.
* Coarse Thread:It is sharper and deeper than the Drywall Screw’s coarse thread, which help the chipboard screw digs deeper and stay tight into the soft materials, and cut through material cleanly.
* Rib: The rib under the screw head help the screw do not slip.
* Straw Rope: The straw rope help the screw do not slip.
* Our Advantage: Adopt high-speed cold heading machine to form one piece, high strength. Self-owned heating treatment producing line,which can promise screws hardness and strength well perform always.Stable drilling speed, not easy to break.
