Screws for holding the original factory hard jaws onto Columbian vises - specifically the Columbian D45-M4, Craftsman 506, and any other vises that fit the specifications listed below 



Some D45 may use 5/16" screws, in which case this is not the right listing, test with a 1/4 and 5/16 screw to see which threads fit your D45 (or measure the major diameter of an existing screw).  Screw diameters are measured by the largest outside diameter of the threads (the "major diameter").

The largest diameter of the flat head is .367" +/- .005"
The overall length is approximately .625
Thread is 1/4-20
Grade 8 steel fasteners
Included angle of the head is 30 degrees
NOTE - this is a 30-degree included head angle.  If you need 40 degree and a smaller head angle like .332", see my other listings for the smaller variant of this.
5/32 hex socket head

Set of four (4) screws

Please check that these values match your jaws or existing/broken screws before ordering.
