To make the process even more efficient, KlevKlip pairs perfectly with a custom-designed screw from Blackhawk Fasteners—engineered specifically to simplify clip installation and ensure a secure, precise fit every time. Together, they offer a streamlined solution for faster, neater decking projects.

Material

The screw material is one of the most important factors when making your purchasing decision. Getting this wrong can have a huge impact on the strength and durability of your project.

Blackhawk Protect is a high-grade, tri-layer coating process. These layers are joined together through a chemical process which results in a tightly bonded coating on the screw. Along with conforming to AS 3566.2 Class 3, Blackhawk Protect has advantages like:

Superior corrosion (rust) resistance over non coated/galvanised fasteners
The unique layering process reduces any damage to the coating if the screw is scratched
Less risk of premature corrosion due to reactions with other metal types

Blackhawk Protect, like all class 3 equivalents, is not recommended for applications within 5km of breaking surf or in close proximity to swimming pools.

304 Extreme Stainless Steel has an improved formula when compared to standard 304 Stainless Steel. This results in a higher level of corrosion resistance. 304 Extreme Stainless Steel:

Protects the screw from corrosion in most external applications
Has an attractive silver finish
Has greater corrosion protection than standard 304 Stainless Steel

304 Extreme Stainless Steel is not recommended for applications within 1km of breaking surf or in close proximity to swimming pools.

Point Type

The point of the screw will determine what it is capable of screwing through. The screw point that you use will be dependent on the material you are using for your project and if you are pre-drilling. Different species of timber have different hardness levels. This will determine the need for pre-drilling. It is best practice to test the screws on an off-cut to ensure the desired result is achieved. It is recommended that you always pre-drill the ends of decking boards as they are prone to splitting.

TYPE 17 POINT

Type 17 refers to the long, cut section at the point of the screw.

Helps to remove debris when being driven through timber
Reduces the need to pre-drill into softwood timber

DRILL POINT

Drill point refers to the sharp, drill like point at the end of the screw.

Cuts into the timber or metal creating its own pilot hole
The timber drill points reduce the need to pre-drill softwood and hardwood timber
The metal drill point eliminates the need to pre-drill into light gauge metal

Head Type

Choosing the right head type can have a big impact on the overall finish of the screw n your deck, some heads are better suited to certain wood types and careful consideration should be made to ensure you get the right head for your screw.

BUTTON HEAD

A washer-like head helps the screw to finish flush with the work surface.

WAFER HEAD

A low profile head that is rounded. A flat underside helps the screw finish flush with the work surface.
