Qualifying your Punch-Pin Application

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.
