PFS: Industry Leading Stud Welding Distributor

Founded in 1987, Production Fastening Systems (PFS) has become a well-established stud welding distributor that has now been serving the offshore, shipbuilding, and steel fabrication industries for more than 30 years. In addition to the superior quality stud welding equipment and materials, we distribute arc stud and capacitor discharge stud welders, tube separation assemblies, weld studs, cable hangers, and more. PFS is a leader in new technologies within our industry. Over the years, we have introduced several new and revolutionary products: pneumatic tube supports (PFS SLP-type); pneumatic channel brackets (PTCB); grating fasteners; and the PFS slotted cable hanger, our best-selling product, which has enjoyed a “zero rejection” reputation since 1991. Today, these metal fastening products are specified and used by the offshore fabrication, shipbuilding, and steel fabrication industries all over the world.

Gerry Keller, President

PFS started in 1987 as a gamble in a growing industry. Gerry has since nurtured his vision into a thirty-year-old business with customers all over the world and counting. Within those thirty years of hands-on experience, Gerry has become an expert in the stud welding and fastening industries, handling nearly every problematic situation that so often emerges in a challenging and highly technical industry.

In addition to being the president of PFS, a devoted husband, father, and grandfather, Gerry officially added Inventor to his long list of accolades and accomplishments upon being rewarded United States Patent No. 9,732,884 for his groundbreaking invention, the T-SEP™. This technology has since been recognized as an innovative solution to the ever-persistent challenge of addressing and suppressing crevice corrosion in caustic offshore environments. Along with the T-SEP, Gerry is responsible for creating innovations that are now staples in the industry: the ESL Slotted Cable Hanger (’91), SLP Pneumatic Tube Support (’91), PTCB Tubing Channel Bracket (’93), SGC Grating Mount (’94), and the FGGC Grating Mount (’98). These products could only have been envisioned and marketed by someone with Gerry’s expertise and determination.

When not managing PFS, Gerry can be found playing with his grandchildren, pulling for the New Orleans Saints and De La Salle Cavaliers (’71), or immersed in his beautiful and always changing garden. Lastly, Gerry would tell you that his greatest accomplishment and joy in life has been his forty-seven years of marriage to his beautiful and equally devoted wife, Connie. As Vice President of PFS, Connie, or as she’s known to her 9 grandchildren- “Peaches”, has worked alongside Gerry to not only create a viable and productive business but, most importantly, a happy and healthy family with plans to see the business grow even further.


Though the quality of our stud welding equipment and metal fastening products is unparalleled, it is the quality of our service that truly sets us apart from any other stud welding distributor. Your experience with PFS does not end with a product order. The performance of our stud welding equipment is critical to our customers’ operations. That is why our skilled, factory-certified technicians armed with more than 20 years of field stud welding experience are always available to provide our customers with on-site equipment training, and that is why we are always happy to fill custom orders, meeting our client’s specifications time and time again.
