Overview

This specialized die is intended for gunsmiths and firearm enthusiasts who are threading bolt handles for aftermarket bolt knob installation. It is set up for 5/16"-24 threading and is suited to bolt-action rifle customization where a compatible bolt knob is being added. The tool is focused on a specific shop task rather than general-purpose use, so it is best suited to users who already know the thread requirement for their project. For rifle builders and tinkerers working on bolt handle modifications, it provides a dedicated option for that narrow application.
