Abstract
A hook fastener portion including a thin strong flexible plate like backing and a multiplicity of resiliently flexible spaced hook members projecting at generally a right angle from an upper surface of the backing. The hook members each comprise a stem portion attached at one end to the backing and a head portion at the end of the stem portion opposite the backing that is flush with the stem portion on two opposite sides, projects past the stem portion on two opposite sides, and has a rounded surface opposite the stem portion to help the head portion enter between loops in a loop fastener portion. The hook members are more easily and firmly engaged with many types of loop fastener portions than the hook members on known commercially available hook fastener portions, in large part because they are very small compared to them, and the hook portions do not have an abrasive feel when contacted by a persons skin.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
