Ruwag Machine Screw Cheese Head & Nut BB BB 4X4 0mm (10) is listed as an auto-part option. Confirm fitment, part number and compatibility before purchase, especially where vehicle-specific matching is required.
Ruwag Machine Screw Cheese Head & Nut 4x40mm (10) is a pack of ten machine screws with cheese head design, paired with matching nuts. These fasteners are designed for securing components where precise mechanical fastening is needed, often in automotive, machinery, or general repair applications.
The cheese head profile provides a flat and wide bearing surface, helping to distribute the load evenly. The screws measure 4mm in diameter and 40mm in length, making them suitable for medium-duty fastening tasks. Buyers should compare this size carefully against their old screws to ensure compatibility with the threaded holes or mounts on their equipment or vehicle parts.
This listing includes both the screws and nuts, allowing for immediate assembly without separately sourcing nuts, which is convenient for replacements or projects requiring matched pairs. The set comes as new parts, ensuring clean threads and reliable fastening behavior.
- Quantity: 10 screws and nuts

When purchasing, verify the diameter and length against your original fasteners or component requirements. If unsure about the exact specifications or alternative part options, contacting the sales desk or submitting a request for a part may provide further assistance.
