Discover more about the Scroll™ Nuts range.

A type of 2-Way Security Nut, this component features a patented Scroll™ drive, meaning it can only be installed or removed using the matching Scroll Driver Tool. The patented Scroll drive is rounded in design, providing no sharp angles for regular hand tools to grip and offering an aesthetically pleasing finish to a security fixture.

Scroll Nuts offer a high security solution against crimes such as theft and vandalism, making them an ideal choice for installations which require tamper proofing measures to be in place. As their design results in no sharp edges, this also enhances the safety aspect of this security fastener.

Materials

Scroll™ Nuts from Accu are manufactured in 303 S31 Stainless Steel as standard. A Chemical Matte Black finish is also available for this security nut.

Sizes

Accu’s Scroll Nuts are stocked in a wide range of metric sizes, from M3 up to M30, making them suitable for industrial applications and home security projects alike.
