PennEngineering, headquartered in Danboro, PA and founded in 1942, is a global leader in fastening solutions and the parent of PennEngineering, PennEngineering Automotive Fasteners, and pennTool™ Group. PennEngineering companies provide fastener and fastener installation design and product solutions worldwide for diverse industries, including electronics, computer, data/telecom, medical, automotive, marine, aerospace/aircraft, and general manufacturing.
When K.A. Swanstrom founded Penn Engineering & Manufacturing Corp. in 1942, he did so with a revolutionary new product: an easy-to-install, self-clinching fastener that provides load-carrying threads in metal sheets too thin to be tapped.
At first, Mr. Swanstrom produced his innovative design with four machines in a Doylestown, Pennsylvania garage. This simple operation soon gave way to a modern facility in Danboro, Pennsylvania because manufacturers and engineers alike recognized the benefits of self-clinching fasteners. They not only reduced time, labor, weight and inventory on many assembly jobs, but they also opened up a whole new world for engineers and designers, making a wide assortment of thin-metal designs possible for the first time.
Industry-wide acceptance led to earnest production of self-clinching fasteners shortly after World War II. As industry’s need to hold together ultra-thin and ultra-light metals grew, so did the product line. Over the years the original self-clinching fastener design was modified to meet hundreds of new design applications.
Today, PennEngineering is a global company and industry leader with manufacturing facilities in Danboro, Pennsylvania; Winston-Salem, North Carolina; Galway, Ireland and Kunshan China. Our products are sold worldwide through an extensive channel of engineering representatives and distributors.
PEM® brand fasteners utilize self-clinching, broaching, flaring, surface mount, or weld technology to provide strong, reusable, and permanent threads and mounting points in thin sheetmetal or P.C. board materials.
SI® brand inserts employ press-in, molded-in, or heat/ultrasonic installation methods to provide strong, reusable, permanent threads in plastic materials.
ATLAS® brand blind threaded rivets provide strong and reusable permanent threads in sheet materials where only one side is accessible.
The STICKSCREW® system is a unique small screw installation system which eliminates expensive screw handling equipment and loose hardware. The screws are tightened to an exact torque as determined by the stick/screw design.
PEMSERTER® presses are designed to safely, reliably, accurately, and quickly install PEM fasteners. No matter how complex or simple an installation challenge may be, using the PEM fastener and PEMSERTER press system will provide you with quality results.
pennTool™ Group brings quality, cost effective tooling and machine part solutions to fastener and component manufacturers across various industries. As a premier fastener manufacturer, PEM is also expert at the design and manufacture of precision tooling for heading and screw machine operations.

At PennEngineering, our goal is 100% defect-free product. To this end, we have adopted a manufacturing strategy of defect prevention rather than defect detection. We use statistical tools throughout our manufacturing processes to monitor the performance and assure effective quality control of each process step. If a non-conforming situation arises, it is resolved immediately with the use of appropriate quality assurance tools.
We are members of the Automotive Industry Action Group (AIAG) where we work together with other member companies to resolve issues critical to the automotive supply chain.
The majority of part numbers are compliant with the current revision of the European RoHS directive (2002/95/EU). We are committed to helping our customers select RoHS compliant products and offer this general statement regarding compliance of our fasteners to the RoHS directive. To check status of specific product types go to the Product Compliance Lookup on our website. If compliance certification on specific part numbers is needed, we can supply such certification if a list of our part numbers is supplied. Submit your request to RoHS@pemnet.com.
