Milling ribs under countersunk head: the decorative countersunk head with twelve milling ribs on the bottom head allows the stainless steel C1 terrace screws 5 x 50 mm to be completely countersunk and ensures a flat fit of the screw heads.
Screw tip: when attaching to the wood, the stainless steel C1 terrace screws 5 x 50 mm grips faster through the cutting tip and prevents the terrace screws 5 x 50 mm from looping. When screwing in, it helps by facilitating penetration of the thread thanks to its pre-drilling effect.
End mill at the thread end (reaming part): the special thread geometry with end mill at the thread end (reaming part) in combination with a sliding coating significantly reduces screw-in times.
Torx drive: thanks to the T-drive, the bit holder of the stainless steel C1 terrace screws 5 x 50 mm head is tumble-free, which allows effortless, safe and precise work without splitting or splitting the timber.
TX 25 magnetic bit: the included TX 25 magnetic bit made of tool steel is a perfect fit and allows highly efficient power transmission.
Notes: Depending on the density and moisture level of the wood, pre-drilling of the wood may be necessary. Work at low speed, preliminary tests generally required. For an absolutely perfect laying look, lowering the drill holes is recommended. Per m approx. 32 pieces patio screws required. A minimum screw depth of 4 x the diameter must be guaranteed. Not suitable for heavily tannin-containing woods such as oak, robinia etc.
