Fastening applications can be challenging, especially when trying to determine the best fastener for the job.  A popular question we are often asked here at R.V. Evans is “when should I use collated pins vs. collated screws in my fastening application?”  Our recommendation weighs heavily on the material you need to fasten together in the application.

In our opinion, the Muro wood to steel floor screws are the best for utility  trailers where the customers are attaching 2″ thick wood to a steel frame. They have a larger diameter and a much larger head size than the Aerosmith pins. This holds the wood better and has less chance of pull-through. In most cases, the Muro screw is faster than pre-drilling and using bulk screws. That is its best-selling feature.

The Aerosmith pins are 5-10 times faster than screws. Their pullout values and cost is comparable to collated screws. If they are being used for heavy gauge steel you will need to use the high pressure system.  This requires the purchase of a high-pressure (400 psi) air compressor, hose, and tool. With the low pressure tools, any jobsite compressor will work. For trailers or truck boxes that are fastening plywood or sheeting to steel, there isn’t really any comparison as long as the volume justifies the tool cost. The Aerosmith pins provide a huge labor savings.  We have sold Aerosmith for construction use when the customer was attaching plywood or hardy board to steel studs. Both times the customer was replacing bulk screws with the low pressure Aerosmith system and they loved the speed and ease of use.
