FAQ on nuts, bolts and washers
How do I choose the right nut and bolt fasteners for my project?
Choose fasteners based on the materials you’re joining, the required strength, and exposure conditions. For outdoor use, stainless steel or galvanized nuts and bolts are best to prevent rust and corrosion.
What are nut and bolt fasteners used for?
Nut and bolt fasteners are used to securely join two or more materials together, whether in construction, woodworking, or machinery. They provide a strong and removable connection, ideal for both temporary and permanent assemblies.
What is the purpose of a washer in a fastener assembly?
Washers are placed between the nut and the surface of the material. They distribute pressure evenly, protect surfaces from damage, and help prevent the nuts and bolts from loosening over time due to vibration.
