If you’re working with timber, a Type 17 screw is one of the most versatile screws you can use. Known for its split-resistant Type 17 tip, these screws are perfect for hardwood, softwood, decking, furniture, and general carpentry projects.
At FIXINZ, we stock a full range of Type 17 screws in HEX, Countersunk (CSK), Wafer, Bugle, and Batten heads, so you can pick the right screw for your project.
What Makes a Type 17 Screw Special?
The defining feature of a Type 17 screw is its self-tapping, sharp, notched point (called a Type 17 auger point).
-
Type 17 auger point – cuts a small channel in timber to prevent splitting
-
Reduces the need for pilot holes in most softwoods and many hardwoods
-
Full-threaded shank – ensures a strong hold in timber
Type 17 screws are designed for clean, precise, and fast installation, making them a favourite for both professional tradies and DIY enthusiasts.
Type 17 Screw Head Options at FIXINZ
Depending on your project, you can choose from several Type 17 screw head types:
-
HEX Head – perfect for heavy-duty timber, structural framing, and outdoor projects
-
Countersunk (CSK) Head – flush finish for furniture, cabinetry, and finish carpentry
-
Wafer Head – wide, low-profile head ideal for general wood applications
-
Bugle Batten Head – pulls timber tightly together, often used in plasterboard, cladding, or decking
Each head type has a specific use case, so choosing the right one helps ensure a strong, neat, and long-lasting fix.
When to Use Type 17 Screws
Type 17 screws are extremely versatile. Here’s when they work best:
-
Hardwood or softwood – prevents splitting even in dense timber
-
Decking & outdoor timber – especially with galvanised or stainless steel variants
-
Furniture & cabinetry – CSK or wafer heads give a clean finish
-
Framing, battens & cladding – bugle or batten heads pull timber tightly together
Why Choose Type 17 Screws?
-
Prevents Splitting – The Type 17 tip removes timber rather than forcing it apart.
-
Multiple Head Options – HEX, CSK, Wafer, Bugle, and Batten heads cover nearly every timber project.
-
Faster Installation – Often eliminates the need for pilot holes in softwoods.
-
Durable & Weather-Resistant – Choose stainless steel or galvanised screws for outdoor use.
Pro Tips for Using Type 17 Screws
-
Even though they cut their own pilot hole, pre-drill for very hard or dense hardwoods to prevent screw breakage or wood splitting.
-
Match the head type to your project for strength, appearance, and functionality.
-
For outdoor decking, stainless steel Type 17 screws resist rust and corrosion.
