Ruwag Square Drive Chipboard Screw BB BB 4X4 5mm (25) is listed as an auto-part option. Confirm fitment, part number and compatibility before purchase, especially where vehicle-specific matching is required.
Ruwag Square Drive Chipboard Screw 4x45mm (25) is designed for secure fastening in chipboard materials. This type of screw features a square drive head, which provides better torque transfer and reduces cam-out compared to traditional Phillips or slotted screws. It is typically used in woodworking, furniture assembly, or construction where chipboard panels need to be firmly joined.
The 4x45mm dimensions indicate a screw diameter of 4mm and a length of 45mm, suitable for medium-thickness chipboard. When selecting this screw, compare it with the old fastener to ensure the diameter and length match the requirements of your project. The square drive design often requires a compatible bit for installation, so make sure you have the right tools to match the square recess on the screw head.
This listing includes 25 screws, ideal for those needing a batch for multiple joints or repairs. Because the screws are a new part, they come ready to use for replacements or new installations where chipboard connections must hold steady under load.
- Square drive head for secure, slip-resistant fastening
- 4mm diameter, 45mm length suited for chipboard
- Pack of 25 screws to cover small to medium jobs
