Drywall Screw

  • Material: C1022A, Case Harden
  • Head: Bugle head
  • Recess: Phillips
  • Thread: Fine thread, Coarse thread
  • Diameter: 3.5mm-6.3mm (#6 – #14)
  • Length: 13mm-152mm (1/2″ – 6″)
  • Surface: Black / Grey Phosphated, Zinc Plated, Nickel Plated

Coarse thread drywall screw are used to fit wood to wood. Rough teeth help to protect the grain. Therefore, the damage probability of wood grain is very small, so the fastening effect of coarse teeth on wood products is better.

Fine thread drywall screw are mainly used to connect metals. For high strength metal products, fine thread tighten better.

 

Chipboard Screw

  • Material: Carton steel, Stainless steel 304/316
  • Head: Countersunk head, Pan head, Wafer head
  • Recess: Pozi, Phillips, Torx, Combination
  • Thread: Fine thread, Coarse thread
  • Surface: Black / Grey Phosphated, Zinc Plated, Nickel Plated

Chipboard screws are commonly used in woodworking and construction projects to secure chipboard, particleboard, and other similar materials. They have a coarse thread and sharp point for easy insertion and provide strong and reliable fastening.

Self-drilling Screw

  • Material: Carton steel, Stainless steel 304/316
  • Head: Hexagon washer, Flat, Pan, Truss
  • Recess: Phillips
  • Surface: Zinc Plated, Nickel Plated, Black/Grey Phosphated, Dacromet, Ruspert.

Self-drilling screws are commonly used in metalworking and construction projects. They have a drill-like point that allows for easy and efficient installation without the need for pre-drilling. They are ideal for fastening metal sheets, steel frames, and other materials that require drilling and tapping simultaneously.

Self-tapping Screw

  • Material: Carton steel, Stainless steel 304/316
  • Head: Flat head, Pan head, Truss head
  • Recess: phillips
  • Surface: Zinc Plated, Nickel Plated, Black/Grey Phosphated, Dacromet, Ruspert

Self-tapping screws are commonly used to connect thin metal plates, such as steel plates and saw plates. The process involves creating a threaded bottom hole in the connecting piece and then screwing the self-tapping screw into that threaded bottom hole. The self-tapping screw’s thread has a higher hardness, allowing it to tap out the internal thread in the connecting piece’s threaded bottom hole, thus forming a secure connection. This eliminates the need for pre-drilling or tapping separate holes for the screws.

Machine Screw

  • Material: Carbon Steel,Stainless steel 304/316
  • Head: Flat,Pan,Truss
  • Recess: Slotted, Phillips, Combination, Pozi
  • Size: All Sizes
  • Surface: Zinc, Nickel, Brass Plated

Machine screws are primarily utilized to fasten connections between components with tight threaded holes and those with through holes. This type of connection, known as screw connection, eliminates the need for nuts and is considered a detachable connection. Machine screws can also be used in conjunction with nuts to fasten connections between two parts with through holes.

Wood Screw

  • Material: Carbon Steel,Stainless steel 303/304/316
  • Head: Flat,Hex,Hex Flange, Oval, Round
  • Recess: Slotted, Phillips, Combination, Pozi
  • Size: All Sizes
  • Surface: Zinc Plated

Wood screws are commonly used in woodworking projects to securely fasten wooden materials together. They are widely employed in furniture assembly, cabinetry, framing, and general carpentry applications due to their reliable holding power in wood.

 

Collated Screw

  • Material: C1022A, Case Harden
  • Head: Bugle head
