The From the Anvil 5mm Male & Female Screws Pewter are replacement bolts for lever handles and come in pairs. The screws are 5 x 90mm and the sleeves are 20mm. Pewter Screws The screws have a pewter patina finish - this has anti-corrosion properties and can be used internally or externally. To remove dirt deposits, simply wipe over with a lightly oiled cloth from time-to-time and this will restore it to its original condition. Do not use any form of aerosol spray or metal cleaner. Other Variations They are also available in a black finish - sold as a separate product.
