Greenlee 20963 – Frequently Asked Questions

1) What is the Greenlee 20963 draw stud and what does it do in a knockout driver?
The 20963 is the threaded draw stud that pulls the punch through the sheet metal on a Greenlee hydraulic or battery-powered knockout driver. It is a replacement wear part: when the stud stretches, galls, or strips, the driver stops seating punches properly and swapping the stud restores the assembly. Round profile, sized 3/8 to 3/4 x 4.8 inches, catalog number 20963.
2) Will the 20963 draw stud work with a manual ratchet knockout set?
Greenlee specifies the 20963 for its hydraulic and battery-powered knockout drivers, and recommends battery or hydraulic use to get full life out of the stud. If you are punching with a hand ratchet wrench setup, order the draw stud that matches that ratchet tool rather than this one.
3) How do I confirm I am ordering the right Greenlee draw stud for my driver?
Greenlee marks each draw stud with the catalog number and size right on the part. Pull the old stud, read the stamp, and match it. For this one the marking reads 20963 with the 3/8 to 3/4 size. That is the fastest check in the tool crib and avoids ordering by guess.
4) Do I need anything else besides the draw stud to punch a knockout?
The 20963 is the stud only. To make a hole you still need the driver (hydraulic ram or battery tool), the punch and die set for the conduit size you are cutting, and a pilot hole drilled for the stud to pass through. If your punch or die is also chewed up, replace those at the same time, since a worn die is what overloads the stud in the first place.
5) Why does my draw stud keep breaking, and will this one hold up better?
Draw studs are the sacrificial link in a knockout set, and they fail from off-axis loading, dull punches, or over-thickness material. The 20963 has a precision round profile so it engages concentrically through the punching cycle, which is what keeps the load straight. Greenlee also recommends running it on battery or hydraulic power rather than a manual setup to maximize stud life. Keep the threads clean and greased and stay within the punch's rated material thickness.
