Product Description
The Timbermate 5.0x90mm Wood Screws Countersunk are steel wood screws sized at 5.0mm diameter by 90mm (3½ inch) length, made for timber and wood-based material fixing.
Key specs
- Size: 5.0 x 90mm (3½ inch)
- Head: countersunk, sits flush with the surface once driven in
- Material: steel
- Suitable for: timber, chipboard and other wood-based materials
Head design
The countersunk head allows the screw to sit level with the surrounding surface rather than standing proud. This is useful where a flat finish is needed or where a panel or fitting is fixed over the top afterwards.
Length and diameter
At 90mm, this screw is longer than shorter general-purpose wood screws, allowing deeper penetration into timber components. The 5.0mm diameter is aimed at medium to heavy duty wood fixing rather than light trim work.
Typical use
Timbermate lists this size for carpentry, framing and general building work, and for fixing structural boards and wooden components where a longer, deeper fixing is required. It is specified for wood and wood-based materials such as chipboard — not for masonry or metal fixing.
Steel construction is stated for durable fastening in timber fibres and engineered wood such as chipboard and plywood.
