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.

(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.
