Greenlee 7212SP22 Round Draw Stud Speed Punch

Product Description

The GREENLEE 7212SP22 is a round draw stud designed as a replacement component for use with the Greenlee SPEED PUNCH System. The draw stud is the threaded fastener that pulls the punch cutter through sheet metal, conduit bodies, electrical enclosures, and similar knockout applications. It engages with the hydraulic or manual punch driver and transfers pulling force directly to the punch die. Electricians and maintenance technicians rely on properly functioning draw studs to maintain consistent, clean knockout cuts and to protect the punch tooling from premature wear or misalignment.

This draw stud is intended for use within the Greenlee SPEED PUNCH System component lineup, making it a direct service and replacement part for that platform. Typical install scenarios include panel fabrication, enclosure modification, and conduit entry work in both residential and commercial electrical applications. When a draw stud shows signs of thread damage, galling, or deformation, replacing it with the correct OEM-specification component restores system performance and protects the punch and die from secondary damage.

Installation Notes

Installation of a draw stud is typically performed by a licensed electrician as part of knockout punch tool maintenance or repair. Before servicing punch tooling, de-energize and lock out any equipment the work will be performed on in accordance with NFPA 70E lockout/tagout requirements. Inspect mating threads on the punch driver and die for damage before installing the replacement stud. Do not use impact tools to thread or remove the draw stud, as this can damage threads and compromise subsequent knockout operations.
