Scroll Nuts & Scroll Bolts

Scroll Nut showing drive & release grooving

special Scroll Nut drive tool showing internal seclock drive lugs

Scroll Nuts are tamper resistant, releasable Security Nuts and Scroll Bolts are the ultimate security fixing. They offer a clever solution for those situations where you need an anti tamper fixing that can also be undone when the need arises. The Scroll Nut or Scroll Bolt is installed and removed with the aid of a special driver tool.  The 1/2" drive security driver is cross drilled with a hole that allows it to be used with a 'T' bar or a standard socket drive set.

The special grooves cut into the outer surface of the scroll nut accommodate the special driver lugs in the recessed cup to allow the nut to be tightened or released.  Scroll nuts are made from A2 Stainless Steel. As a special manufacturing option, the scroll nut can also be made with just a drive groove, converting the nut into a one way unit which performs in the same way as a shear nut. 

Subject to quantities, Scroll Bolts are also available to special order as are Scroll Nuts in other sizes. They can also be produced in case hardened steel for higher torque applications
