Abstract
A ribbed dowel for aligning workpieces is disclosed including a cylindrical body having an outer surface, a first end, and a second end, a plurality of ribs spaced over the outer surface, a round circular first face on the first end, a round circular second face on the second end, and wherein the ribbed dowel is composed of a material other than a polypropylene homopolymer having a density of 0.905 g/cm3, a melt flow rate of 60 g/10 min, a Rockwell hardness of 107, a Durometer hardness of 84, and a melting point of 330° F.
Claims17
A ribbed dowel for aligning work pieces comprising:
- a cylindrical body having an outer surface, a first end, and a second end substantially similar to said first end;
- a plurality of ribs each having a first tapered end and a second tapered end, first and second sidewalls having lower edges intersecting said outer surface and spaced parallel to one another over said outer surface, wherein each said rib extends longitudinally from said first end to said second end, and wherein at least one of said ribs deformable against at least one opening of said workpiece;
- a round circular first face on said first end wherein said first tapered end intersects said first face;
- a round circular second face on said second end wherein said second tapered end intersects said second face;
- and
- wherein said ribbed dowel is composed of material other than a polypropylene homopolymer having density of 0.905 g/cm3, a melt flow rate of 60 g/10 min, a Rockwell hardness of 107, a Durometer hardness of 84, and a melting point of 330° F.
