Abstract
A fastener includes an axial shank and a clamping face extending radially from the shank. A plurality of serrations are formed on the clamping face and extend radially from a shank periphery to an outer periphery of the clamping face. The shank periphery is axially displaced away from the clamping face relative to the outer periphery of the clamping face to define a ramped surface.
Claims19
A fastener comprising:
- an axial shank having a free end;
- a clamping face extending radially from the shank;
- a washer bounding the clamping face defining a planar surface;
- and
- a plurality of serrations formed on the clamping face and extending radially between the shank and the washer, wherein each serration increases in axial height from the washer to the shank defining a ramped surface projecting towards the free end and having a first portion protruding above the planar surface and a second portion extending below the planar surface.
