Nails, bolts and washers play an essential role in binding objects together to ensure household items or parts of a building are safely connected. They can be inserted into a number of materials and are designed to grip and hold two components together for a reliable, long-term fix. They are made from hardwearing materials, so can be used to fasten an array of objects. Some nails, bolts and washers also have a protective coating that guards against rust and wear, making them suitable for exterior projects. Different thread designs and head types are available to suit various tasks, such as lightweight or heavy-duty assemblies, while a vast selection of sizes, strengths and finishes is available to match an array of jobs.
