The CLE-LINE C65616 is a hex rethreading die designed to chase and restore damaged or corroded external threads without cutting new material away. Built from carbon steel, this die handles 11/16-11 UNS thread size in a right-hand direction. It is a solid, non-adjustable die suited for maintenance and repair work across mechanical, plumbing, and industrial applications. Plumbers, pipefitters, maintenance mechanics, and field service techs reach for rethreading dies when a bolt, stud, or pipe fitting has thread damage that prevents proper engagement. The hex body allows a standard die stock or wrench to drive it cleanly over the damaged fastener.
This die is used wherever 11/16-11 UNS external threads need to be restored on bolts, studs, or fittings. Common applications include maintenance repair on industrial machinery, pipe assemblies, and structural fasteners. It is appropriate for shop bench work as well as field repair situations where replacing a threaded component is not practical. The right-hand thread direction is standard for the vast majority of fasteners encountered in these trades.
Designed for use on external 11/16-11 UNS right-hand threaded fasteners including bolts, studs, and threaded rod. Suitable for use with standard hex die stocks sized to fit the die outer dimension.
A licensed mechanic, pipefitter, or maintenance technician should confirm the original thread specification before running the die. Secure the workpiece firmly before applying the die to prevent thread misalignment. Apply cutting or tapping fluid to the die and fastener to reduce friction and extend tool life. Never force the die past resistance - back off and clear chips regularly to maintain clean thread form.
