Greenlee 1614SSP Knockout Draw Stud 3/8 x 2-13/16

Greenlee 1614SSP Knockout Draw Stud

The Greenlee 1614SSP is a steel knockout draw stud built for electricians and contractors who punch conduit holes in panels and enclosures. Its hardened construction resists wear during repetitive use with hydraulic drivers. The transparent finish allows quick visual inspection of the stud surface before each job. This accessory is designed for professional trade applications where reliability matters.

Compatibility check before ordering

Verify that your hydraulic driver accepts a 3/8 inch draw stud before purchasing this item. The stud length measures 2-13/16 inches overall, so confirm the driver stroke and puller spacing can accommodate that dimension. Ensure the punch and die set you intend to use matches the stud thread and diameter specifications. This component is not suited for manual ratchet drivers or non-hydraulic punch systems.

Behaviour under sustained load

The steel body maintains dimensional stability during extended punching cycles without bending or thread deformation. Heat generated by repeated hydraulic strokes dissipates through the solid shank, preventing galling on the driver interface. The stud retains full engagement strength across multiple hole sizes when paired with matched Greenlee punch sets. It is not intended for continuous automated production lines exceeding typical trade workloads.
