Washers are flat, disk-shaped fasteners used with bolts, screws, or nuts to distribute load by increasing bearing surface, reduce vibration, or protect surfaces during fastening. They are essential in applications requiring secure, stable joints in construction, machinery, and equipment assembly.

Common Types and Features:

Flat, split lock, internal/external tooth lock, fender, and finishing washers
Inch and metric sizing available
Materials include steel, stainless steel, brass, and nylon
Plain, zinc-plated, galvanized, and specialty coated finishes
Used to reduce wear, prevent loosening, and improve joint stability

Flat Washers — Flat Washers Flat washers distribute load and reduce surface wear under nuts and bolt heads, helping prevent damage to materials and providing a smooth, even surface for secure fastening.

Lock Washers — Lock Washers Lock washers are designed to prevent fasteners from loosening due to vibration or torque. They create tension or bite into surfaces, adding extra security in mechanical, automotive, and high-vibration applications.

Fender Washers — Fender Washers Fender washers have an extra-wide outer diameter for better load distribution over soft or oversized holes, commonly used in sheet metal, plumbing, and automotive applications to prevent pull-through and surface damage.

Square Washers Square washers provide a larger bearing surface than round washers and are often used with square head bolts in wood or structural applications to prevent pull-through and distribute load evenly.
