Model: square washers
Material: steel hot dip galvanized
Port: Shanghai
Application: Square washers are produced for use on poles and crossarms to distribute the stress.
They prevent the crushing of wood fibers and protect the drilled holes. Square washers also provide alignment checking.
They are installed under bolts, nuts or rods to provide a broader bearing surface and increase the compression grip of the tightened nuts.
Square washers are produced in carbon steel SAE 1010 to 1020, hot dip galvanized to ASTM A-153.
