The HECO-TOPIX 6 x 100mm A2 stainless steel countersunk screw is a high-performance timber screw designed for fast, secure fixing in a wide range of timber construction and woodworking applications. Its countersunk head provides a neat, flush finish, while the TX25 drive allows positive torque transfer during installation.
Manufactured from A2 stainless steel, the screw provides good corrosion resistance for internal and external applications where stainless steel is required. The HECO-TOPIX design incorporates specialist tip and thread geometry to support fast installation, reduce the risk of timber splitting and provide reliable fixing performance.
The HECO-TOPIX is a specialist timber screw designed for efficient and reliable fixing in timber construction and woodworking applications.
Key features include:
HECO-TOPIX screws are suitable for a wide range of timber construction, carpentry and woodworking applications.
Typical applications include:
The appropriate screw diameter and length should be selected according to the timber species, connection design, required penetration and expected loads.
For structural applications, the appropriate HECO technical documentation and project or construction specification should be followed. Always confirm the required dimensions, material grade and performance requirements for the intended application.
Is this HECO-TOPIX screw suitable for outdoor use?
Yes. This HECO-TOPIX screw is manufactured from A2 stainless steel, providing good corrosion resistance for internal and external timber applications. It is suitable for many outdoor applications where A2 stainless steel is appropriate, including landscaping, timber construction, cladding and general external woodworking.
What drive bit does the HECO-TOPIX 6 x 100mm screw use?
This screw uses a TX25 internal six-lobe drive. A suitable TX25 bit should be used during installation to provide positive engagement and effective torque transfer.
What is the HECO-TOPIX 6 x 100mm screw used for?
The HECO-TOPIX 6 x 100mm screw is designed for timber construction and woodworking applications. Typical uses include structural timber connections, timber framing, staircase construction, landscaping, timber cladding, facade attachment and general carpentry.
Does this screw need a pilot hole?
Pre-drilling is not normally required in many timber applications because of the screw's specialised tip and thread design. However, pre-drilling may be appropriate depending on the timber species, screw position, edge distance and the requirements of the particular installation.
What is the difference between A2 and A4 stainless steel screws?
A2 stainless steel provides good corrosion resistance for many internal and external applications. A4 stainless steel offers a higher level of corrosion resistance and is generally selected for more demanding environments, including applications exposed to higher levels of salt or aggressive atmospheric conditions. The appropriate stainless steel grade should be selected according to the environment and application.
