Greenlee 29451 – Frequently Asked Questions

1) Is the 29451 a Greenlee genuine replacement part?
Yes. The 29451 is a genuine Greenlee draw stud, built as a direct replacement for the stud in Greenlee hydraulic drivers and made in the United States. Buying the factory part is how you keep the thread engagement and shoulder bearing surface matched to the driver ram instead of chancing a generic stud under hydraulic load.
2) What does a draw stud actually do in a knockout punch setup?
The draw stud is the threaded rod that passes through the pilot hole in the panel and connects the punch and die to the hydraulic ram. When the driver builds pressure, it pulls on the stud, drawing the punch through the sheet metal against the die. It is the part that takes the full pulling force, so it is also the part that stretches, galls the threads, or snaps first and needs replacing.
3) My draw stud threads are stripped after a tough punch. Is replacing just the stud enough?
Usually yes, and that is exactly what the 29451 is for. A stripped or stretched 7/16 inch stud is the normal wear item in a hydraulic knockout setup and swapping it restores the tool. Inspect the punch and die at the same time, though: a stud that failed from a dull cutter will fail again on the next hole if the cutting edge is chewed up.
4) Should an electrical shop keep spare draw studs on the shelf?
For any shop running a fleet of hydraulic drivers, yes. The draw stud is the single consumable in a knockout setup and losing one mid-install stops the job. The 29451 is sized at 7/16 inch by 4-1/4 inches, so one part number covers every driver in the fleet that uses that stud size, which makes it an easy line to stock for maintenance and repair of hydraulic driver tools.
5) What is the Greenlee part number for this draw stud?
Order it as Greenlee 29451. That is the manufacturer part number for the 7/16 inch by 4-1/4 inch round draw stud, and it is the number to quote when matching a replacement to an existing hydraulic driver.
