Introducing the PowerSIX™ Security Screw

Versatile tamper resistant self-threading security screw

Ideal for all types of fencing applications, the tri-Lobular self-threading screw eliminates the need for nuts, reducing labour costs & installation time.

For added security PowerSIX™ security screws also feature a unique 2-way (removable) security drive.
Regular 6-Lobe/Pin Torx tooling will not fit this unique security drive.

What are tri-Lobular self-threading screw​s?

Tri-Lobular self-threading screw​s (also known as thread forming screws) are designed to tap (cut) their own threads as they are driven into a pre-drilled hole. This helps to eliminate the need for nuts or pre-tapped holes, dramatically reducing labour costs for installation.

The unique tri-lobular configuration provides a built-in locking device to help ensure joint integrity and resist loosening caused by vibration.
