Securely clamp workpieces with your Wilton vise using these 5" Aluminum Jaw Caps (14830). The aluminum alloy design includes 6 grooves to compensate for the unevenness of certain workpieces, while the deeper V-groove ensures more secure clamping of circular workpieces. They are designed to protect both the vise jaws and the workpiece from marring and distortion during any clamping application. Use them with the Wilton Rubber Magnefix Jaw Caps when clamping taper pins and spherical parts.
