These are the nuts securing the Strut Top Mount to the chassis - the 3 visible on each side when the bonnet is open. 
The original design is a bolt with integrated washer; our part instead has the nut with separate Stainless Steel washer (both included in this part).

Sold and priced individually - you need 3 per side; 6 in total. Discounts for quantity will automatically be applied at payment. 

Important note - we don't charge extra for delivery to Scottish Highlands or Northern Ireland, but parcels may take 1-2 days longer to arrive to these destinations.
