Description / Abstract:
This Standard covers the dimensional requirements, physical
properties, and related test methods for helical spring-lock
washers (# 0 through 3 in.), tooth-lock washers (# 2 through
13⁄4 in.), and plain washers (# 0 through 3
in.).
The inclusion of dimensional data in this Standard is not
intended to imply that all products described are stock production
items. Consumers should consult with suppliers concerning the
availability of products.
NOTE: The word lock appearing in the names of products in this
Standard is a generic term historically associated with their
identification and is not intended to imply an indefinite
permanency of fixity in attachments where the fasteners are
used.
