PUNCH-PIN

Fasten to Sheet Metal ... without drilling.

Now you can fasten light loads to sheet metal in less time than it takes to drill a hole. This simple, quick fastener is perfect for attaching nameplates, wiring clips and small components to metal doors, electrical cabinets, steel tubing, etc.

Simple application. 
Position the Punch-Pin on the tip of the tool, push the tool against the base metal and pull the trigger. The Punch-Pin is driven in a single impact. The fastening is fast and permanent.

No surface preparation.
The hardened steel fastener drives through dirt, oil, grease and most paints. Specially shaped, annular grooves bite into the softer base metal and form a permanent attachment which holds up to 250 pounds. No cleaning, no drilling.

No alignment problems. 
A Punch Pin makes its own hole in the base metal so there is never a problem aligning attachment holes with base metal holes.

A Heavy-Duty Solution to Light-Load Fastening
Metal-Tacks eliminate costly problems associated with other fastening methods. Adhesives are messy and may be less than permanent. Other fasteners that require drilled holes also require perfect alignment between base metal and attachment. In addition, drilling holes may cause damage by drilling too deep, and metal drill chips are difficult to completely clean up.

Punch-Pin selection is based upon the part that is going to be fastened (attachment) and the material that it is going to be fastened to (base metal).

Attachment
Typical attachments are nameplates, wiring clips and small components. The attachments should be less than .040" thick. Unless the attachment is very thin (foil, paper, etc.) it will need to have a hole in it. Hole sizes may range from .078" to .125". Larger holes provide an easier target for the operator.

Base Metal
Punch-Pins will fasten to sheet metal from 14 gage (.075") to 24 gage (.024"). They will also fasten to many soft metals thicker than .075". Metals harder than HRB65 may require a Metal-Tack fastener (available from Amtak).

Punch-Pin Material and Plating
Standard Punch-Pins are manufactured from carbon steel and are bright zinc plated. They will pass a minimum 120-hour salt spray test in accordance with ASTM B117.

Special Fasteners
Punch-Pins may be used for a wide variety of applications including electrical contacts and balance weights. Please call us if our standard Punch-Pin does not fit your application. Our engineers will be happy to work with you in exploring the possiblilty of a special fastener.
