Amtak Fasteners Announces Introduction of Revolutionary Twist-Tack(TM)

EAST PROVIDENCE, RI, March 23, 2004 -- Amtak Fasteners announces the introduction of its self-piercing Twist-Tack(TM) metal fastener. The one-step fasteners attach materials such as rubber, plastic and thin gauge aluminum to steel tubing, aluminum extrusion or lightweight metal castings. The Twist-Tack(TM) achieves hundreds of pounds of withdrawal resistance when applied with a compression riveter, a single impact air tool or Amtak Bench Press.

The patent-pending Twist-Tacks fasten quickly because they do not require a predrilled hole in either the attachment or the base metal. The fastener first punches a hole in the attachment and then forms an anchor cone in the base metal. Fastening takes place when the knurled section of the fastener engages the anchor cone with a cutting, twisting and wedging motion.

"We are seeing a lot of interest in the Twist-Tack(TM) from manufacturers who are using tubing in their products, such as ladders, outdoor furniture and signs," said David Ashton, Vice President of Sales, Amtak Fasteners.

Amtak, a Division of Gripnail Corporation, has over thirty years experience in fastening to the surface of metal. Its unique fasteners include Metal-Tacks, Punch-Pins and Gripnails, which attach light loads such as nameplates, small components and insulation.
