Click on image to zoom


Dull black, plain rim grommet & washer.

Packaged one gross per box.


For best results in setting No. B1 grommets and washers, use an Osborne No. 500 hole punch and an Osborne No. 216 setting die with corresponding sizes. Osborne grommet dies and grommet hole cutters are numbered to correspond with standard size grommets. Grommet dies and cutters should be used with a rawhide hammer or wooden mallet. We recommend the No. 395 hammer for this purpose and the No. 603 Cutting Pad.

These are also set using our Hand Press Machine Osborne No. W-1 or our Pneumatic Machine Osborne No. W-3 with the correspondent dies.
