VersaPin® ST4200 Fastening Tool

Aerosmith introduced the first VersaPin® tool in 2003.  This revolutionary system changed cold-formed Steel fastening forever.  In 2009 Aerosmith introduced the ST4200 High-Speed Pneumatic Pin Nailer to the lineup.  Wherever traditional fastening (screws, nails, bolts, spot welds, etc.) is used, Aerosmith Brand Pins have demonstrated exceptional productivity leaps with SPEED being the biggest benefit.  Now you can do the same job just FASTER!

How it Works

Today's contractors are looking for faster, better, money saving products allowing them to be more competitive in today's challenging market place. Aerosmith's line of innovative fasteners do just that. With Aerosmith, predrilled holes and time consuming screwing are a thing of the past. All Aerosmith pins are made with heat treated steel with a ballistic point which allows the point to penetrate the steel cleanly and quickly for installations 7-10 times faster than conventional methods. The force of friction creates the bond between the steel and the fastener for maximum holding power.
