A pair of new replacement Serrated Vise Jaws for the Prentiss #20 Vise. Check dimensions below for matching your jaws to these. They could fit the # 3, or the #53 and the Monarch 217.
A-2 Tool Steel is Heat Treated to 54-56 Rockwell. The colorful pattern on the serrated jaws happens during the Heat Treating process when nitrogen is used. After Heat Treating, these jaws are surface ground flat and then squared.

Made in the USA.
Length: 4-5/8
Height: 1-3/16
Channel Height: 11/16 (.692) .005 wider for a easy fit.
Channel Depth: .208 Check your depth and if it is 3/16 then let me know so I can adjust channel depth. These numbers came from 2 examples.
Thickness: 5/8 Original thickness is .585 (I made it a bit thicker to add more beef around the screws and to allow the owner to re surface the face).

Bought as replacements for my Prentiss #20 vise which I was restoring, these are a perfect fit and seem to be made of very high quality steel, probably would exceed factory originals if you could find them, they are excellent replacements for worn down originals.
