Ruwag Cup Square Bolt & Nut Black 10x90mm (100) 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 fasteners designed for secure mechanical joining in automotive or industrial applications. This set includes 100 black square bolts with matching nuts, each measuring 10x90mm. The square head design provides a robust grip for tightening tools, often used where higher torque and resistance to loosening is required.
These bolts and nuts are typically used in frameworks or assemblies where the square profile helps prevent rotation during installation or comes useful in slot or channel fittings. Their black finish may offer basic corrosion resistance, suitable for exposed or semi-protected environments. When comparing to your old fasteners, check the head shape, thread size, and length to ensure compatibility.
Choosing this batch is useful for bulk replacements or maintenance projects requiring multiple identical fasteners. Confirm the 10x90mm sizing fits your application by measuring the diameter and length of the existing bolts. The package quantity of 100 pieces supports larger repair or production runs.
