HOW TO USE AMTAK SELF PIERCING FASTENERS ? More Than Just a Fastener, METAL TACK™ and PUNCH PIN™ offer a Complete Fastening System. A lightweight, portable, air hammer is used for making attachments to equipment or machinery. This air tool was designed specifically for attaching METAL TACK™ and PUNCH PIN™ fasteners and operates on 4 to 7 bars (60-100 psi).  The METAL TACK™ or PUNCH PIN™ is held on the tip of a magnetised driver, which allows the operator a clear view of his fastening operation. The operator simply positions the METAL TACK™ or PUNCH PIN™ where he or she wants to fix the part and presses down onto the base metal and then squeezes the trigger.  The air pressure forces the Metal Tack into the base metal which creates its own grip around the Metal Tack assuring an effective and secure fastening that will need up to 115 kg of force to pull it out !!  Specially shaped annular grooves bite into the softer base metal and form a permanent attachment. No Alignment Problems : A METAL-TACK™ and a PUNCH PIN™ makes its own hole in the base metal so there is never any problem aligning holes in the part to be fastened with a base metal hole. No Surface Preparation : The hardened steel fastener drives through dirt, oil, grease and most paints.
