Blackhawk 10 gauge, drill point, countersunk or truss head, Blackhawk Protect or 304 stainless steel or 316 stainless steel, T20 star drive decking screw
Decking screws come in a range of sizes and materials. Choosing the wrong screw can add unnecessary time and cost to your decking project. The Blackhawk Speed Drive decking screws have a range of features that will improve your decking experience.
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 is environmentally friendly and does not contain hazardous substances like lead, cadmium, mercury or hexavalent and trivalent chromium. 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 Stainless Steel
304 Stainless Steel is one of the most common materials used for fasteners:
Protects the screw from corrosion in most external applications.
Has an attractive silver finish
Is the material of choice for most decking professionals
304 stainless steel is not recommended for applications within 1km of breaking surf or in close proximity to swimming pools.
316 Stainless Steel
316 Stainless Steel is a marine grade of Stainless Steel:
Offers the greatest resistance from corrosion (rust).
Can be used in sever environmental conditions
Has an attractive silver finish
Can be used in close proximity to salt water bodies like the ocean and swimming pools
The Blackhawk Speed Drive decking screws come in 50mm and 65mm lengths and are 10 gauge.
Gauge = The Blackhawk Speed Drive decking screws come in 50mm and 65mm lengths and are 10 gauge.
Length = the measurement from the top of the head to the tip of the point.
To determine the length of required screw, you will need to know the type of timber being used for both the decking and joists. When fixing into softwood joists, the screw should be 2.5 times the thickness of the decking board. When fixing into hardwood joists, the screw should be 2 times the thickness of the decking boards. Blackhawk Speed Drive decking screws are not recommended for metal joists.
Drill point refers to the sharp, drill like point at the end of the screw. The Blackhawk Speed Drive decking screws have a patented point designed to reduce the need to pre-drill. The drill point:
Cuts into the timber creating its own pilot hole
Reduces the need to pre-drill your decking boards
Can pre-drill into a greater number of timber species, including most hardwoods
Different species of decking timber have different hardness levels. This will determine the need for pre-drilling. It is recommended that you always pre-drill the ends of the decking boards as they are prone to splitting.
T20 Star Drive
The T20 star-drive has a 6 point, star-shaped pattern. The star-drive shape:
Increases the surface area that the tool connects with
Allows more torque to be applied when driving the screw
Reduces the chances of “cam-out” and damage to the screw or tool
“Cam-out” is a term used when the tool that is driving the screw slips out.
BLACKHAWK provides 2 free 50mm T20 star drive bit that are suitable for use in impact drivers.
A truss head has a smaller profile than a countersunk head and cuts through the decking surface. The Blackhawk Speed Drive decking screws have integrated ribs on the underside of the head. This helps to remove excess timber, resulting in smoother, cleaner finish.
Countersunk Head with Ribs
A countersunk head helps finish the screw flush with the material being fastened. The countersunk head has integrated ribs on the underside. This helps to remove excess timber, resulting in a smoother, cleaner finish.
