About Us

La Casa de los Tornillos (Fuerza Industrial) is a company founded in San Juan, Puerto Rico in 1971. In the past 48 years we have grown from a small (1500 ft2) single store, to a network of 11 stores strategically located around the island (over 2,000,000 ft2 of retail and warehouse space). As Puerto Rico’s premier industrial/construction supplier, we carry products to serve all markets: from the occasional handyman to complex production lines.

We have the largest inventory of industrial, construction and MRO supplies in Puerto Rico and the Caribbean. We carry a wide selection of bolts, nuts, threaded rods, safety equipment, power tools and many other items. That’s why our company slogan is “Not Only Bolts, but Much More”. Our policy is to always have stock (even on rare or hard to find items)… if you need it, we got it!

Our knowledgeable staff is trained to offer you assistance in the proper selection of hardware, tools or equipment for the job on hand. In addition, our engineering department is specially trained to offer you literature, design guidelines and technical information to find and implement solutions to your particular situation. We can also offer material certificates, MSDS or any technical literature upon request for any of our products.

We are committed to provide quality products and services. These and many other reasons make us the leaders in this field.
