Fastener Assembly Useful As Drain Plug
Fastener Assembly Useful As Drain Plug
US Patent:
5188495, Feb 23, 1993
Filed:
Feb 28, 1992
Appl. No.:
7/843204
Inventors:
James D. Jones - Southfield MI
Assignee:
Illinois Tool Works Inc. - Glenview IL
International Classification:
F16B 3300, F16B 4302
US Classification:
411369
Abstract:
A fastener assembly comprises a metal screw and a sealing ring made from an elastomeric material and is useful, in an exemplary application, as a drain plug for an oil pan for an internal combustion engine. The screw head has an undercut, annular recess, within which the sealing ring is seated. The sealing ring has a sealing portion, which when unstressed has an axial thickness smaller than the recess depth, and an adjoining portion or web extending radially inwardly. When unstressed, the adjoining portion has an inner diameter smaller than the major diameter of the threaded portion of the screw shank. The sealing ring when unstressed has an outer diameter larger than the outer diameter of the recess. Moreover, the recess volume is sufficient for the recess to contain the sealing ring over a wide range of cumulative, dimensional tolerances.
