Wood screws come in various head styles, each designed for specific applications and aesthetic preferences. Here are some common head styles for wood screws:
Flat Head (Countersunk or Flat Head):
The flat head is designed to sit flush with the surface of the wood when driven in. It's commonly used when a smooth, finished appearance is desired. There are variations such as oval and bugle heads that are similar to flat heads.
Round Head:
The round head protrudes slightly above the wood surface and provides a more decorative look. It's often used in applications where appearance is a consideration.
Pan Head:
Similar to flat heads but with a rounded top, pan heads have a slightly raised appearance. They are versatile and suitable for a variety of applications.
Truss Head:
Truss heads have a low, wide profile with a large, flat surface. They provide extra support and are often used in applications where additional holding power is required.
Bugle Head:
Bugle heads have a slightly rounded top and a concave underside. They are designed to self-countersink and are often used in drywall and decking applications.
Oval Head:
Oval heads have a rounded top that is slightly more tapered than flat heads. They provide a neat appearance and are commonly used in furniture assembly.
Raised Head:
Raised heads are similar to pan heads but have a higher profile. They are often used when a more visible fastener is desired.
Cheese Head:
Cheese heads have a cylindrical shape with a flat top. They are less common in woodworking but are used in some applications.
Square Drive (Robertson) Head:
The square drive head has a square-shaped socket that requires a matching driver bit. It provides better torque and reduced slipping during installation.
Torx (Star) Head:
The Torx head has a star-shaped pattern and requires a Torx driver. It offers good torque transfer and is less prone to cam-out.
Hex Head:
Hex heads have a hexagonal shape and require a hex driver. They are commonly used in construction and outdoor applications.
Combo Drive (Combination) Head:
Combo heads can be driven using either a Phillips or a square drive, providing flexibility in installation.
