Ruwag Square Drive Chipboard Screw BB BB 4X4 0mm (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 4x40mm (25) is a set of fastening screws designed specifically for chipboard applications. These screws feature a square drive which provides better grip and torque transfer compared to traditional Phillips or slotted drive screws, reducing the chance of cam-out during installation.
This pack contains 25 new screws, each measuring 4mm in diameter and 40mm in length, suitable for joining chipboard components or other similar materials where a secure hold is required. When selecting screws for your project, compare the size and drive type of your old screws to ensure compatibility.
The square drive head shape is particularly useful when demanding higher torque levels and is commonly preferred in woodworking and furniture assembly. This type of screw is ideal if you need reliable, repeatable fastening with reduced stripping.
