No. Our 150mm Flush Head Screws have a self-drilling point to help them start in timber, but the supplied guidance still notes that pre-drilling can be sensible close to timber ends or edges where splitting is a concern.
No. The self-drilling point on our John George 150mm Flush Head Screws is designed to help the fixing start into timber, but it does not mean a pilot hole is never appropriate.
The screws are made from hardened steel with a green organic coating and use a self-drilling point, milling shank and flush head. The milling shank helps clear material as the screw is driven, while the head is designed to finish close to the timber surface.
The supplied product guidance specifically notes that pre-drilling can still be sensible close to timber ends or edges where splitting is a concern. Screw length should also be checked against the actual joint so the fixing obtains useful engagement without the point emerging through an exposed reverse face.
The same 150mm fixing is available in a tube of 10 and a box of 50. Other screw lengths and fixing formats can be compared under screws, fixings and fasteners.
