Good day! We are grateful for your interest in the Elkay LK463 screws and clips. These hex head screws are longer than the standard size. They have 3 different sizes: 1-7/8 inches, 2-1/4 inches, and 2-3/4 inches. These screws can rust depending on the application. There are 28 hex nuts included in this kit. For 2 inches thick countertops, we recommend either this Elkay LK463 or the Elkay LK348. To help you better choose between the two, please check this Specification Sheet for more details. If you're ready to order either of these products, just go to the product's page, click "Add to Cart", fill out the required information, and you'll be all set. Enjoy shopping here at PlumbersStock.com!
