 Product Description

A pair of new replacement Serrated Vise Jaws for the Prentiss #57 and other 7" wide jaws for a Prentiss vise.  I have seen in other jaw widths that Prentiss used one size for all their vise's, a 4-1/2 inch jaw fits all their 4-1/2 inch vises. I know these fit a #57 Prentiss Vise.

 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.

(4x)  5/16:18 Short Head Cap Screws supplied.


These are Premium Handcrafted Jaws. Many imports use powdered metal that gets injected into a mold to save time. I have seen many break at the screw holes. My jaws should be the last you ever buy.


Made in the USA.
