Type 17 Screws What Are They

Although we often use the term Type 17 Screw it doesn’t really refer to the fastener as a whole, the type 17 reference is a manufacturer’s term for the point shape on the end of the screw. When screws are being made the design will include many features, head style, drive type, shank style, material, plate finish etc. and of course the point type. Examples include type 23, type A, type AB, gimlet and type 17.

So just to clarify, type 17 is actually the point end and for type 17 this is a sharp pointed design with a cut out flute to help capture and remove the waste allowing a self drilling type function similar to a drill bit. This self drilling action prevents wood fibres separating which leads to splitting and so these screws are very useful for close to edge work, they  also benefit from fast insertion and self centering starts and so are ideal for use with powerdrivers.

The sharp point means you can also use them in thin steel sheeting without pre-drilling e.g. fixing roofing and cladding sheets. At Scrooz our type 17 fasteners are all branded under our Razr range which denotes their self drilling thread cutting function along with other features.
