Buying advice

When selecting flat washers, consider material (zinc-plated for indoor, stainless for outdoor), inner diameter matching screw size, and outer diameter for load distribution. Bulk packs save money for common sizes like #10, 1/4", and 3/8". For critical structural applications, opt for thicker, hardened washers from reputable brands.
