Ruwag Cup Square Bolt & Nut 8x50mm (5) is listed as an auto-part option. Confirm fitment, part number and compatibility before purchase, especially where vehicle-specific matching is required.
this part is a set of five new fasteners designed for securing components where cup square bolts are specified. This type of bolt, sized at 8x50mm, is commonly used in automotive assemblies that require robust, square-shaped heads for better torque application and fastening stability. The matching nuts ensure a firm lock for assembled parts, preventing loosening due to vibrations.
This bolt and nut set is identified under SKU BB-404868 and is new. While it originates from the Ruwag Cup Square product line, the listing does not specify vehicle make or model fitment, so buyers should compare with the original parts they need to replace by checking the exact bolt dimensions and head shape. This ensures compatibility with the vehicle or equipment’s fastening points. The 8x50mm measurement is crucial for fitment verification.
When ordering, verify that your old bolt measures similarly and has a matching thread pitch to avoid fitment issues. This unit is suitable for applications requiring reliable fastening with a square bolt head and corresponding nut. If uncertain about the correct sizing or fit, use a vehicle parts finder or consult the sales desk for guidance to confirm compatibility.
