Greenlee SPEED NUT is a unique and innovative quick-lock system currently being offered on the market for all Greenlee rectangular and square punches. It consists of an rugged draw stud and a innovative quick-action bayonet coupling which unlike conventional counter nuts is not screwed onto the draw stud but simply pushed onto it and fixed with a turn.
This means longer tool life and faster and easy punching operations – up to three times faster than conventional punching tools.
SPEED NUT is compatible with all Greenlee hydraulic and battery-powered punch drivers and suitable for all square punches from 46.0 x 46.0 mm and rectangular punches from 33.3 x 66.7 mm. With the SPEED NUT, hydraulic punch drivers and special shaped punches Greenlee offers a complete range of punching tools allowing to punch holes easily, accurately and extremely quickly.
Up to three times faster that standerd draw studs.
