What is the proper way to secure a part in a bench vise that might be damaged from the vise teeth?

• A. Use a proper fitting rubber jaw guard on the vise jaws
• B. Increase clamping force
• C. Use a metal shim between part and jaws
• D. Place part directly without protection

Answer: (A)

Protecting a part from vise contact means creating a soft, non-marring surface between the jaws and the workpiece. A properly fitting rubber jaw guard provides a cushioned contact area that distributes clamping pressure more evenly, so the vise teeth don’t gouge, scratch, or dent the part. It also helps the part stay securely in place by reducing the tendency to slip compared with hard metal jaws. Make sure the guard fits the jaws correctly and is clean and in good condition so it seats evenly. Using more clamping force, a metal shim, or clamping the part directly would increase the risk of damage or deformation, so they aren’t suitable ways to protect a part that could be damaged by the vise teeth.
