Butt hinges are the backbone of any door and they are in constant use, so durability and longevity of these parts are essential. A butt hinge is designed to be inset (mortised) into both the doorframe and door. This type of hinge is usually made with a small number of overlapping knuckles (three or four), compared to a continuous hinge.

Stainless steel industrial butt hinges are made of a thicker material than the standard hinge, which helps create an extremely strong and robust piece of hardware that will stand up to any harsh industrial environment.

Whether you need butt hinges for corrosive marine environments, spray booths, trucks/trailers, or any other application, SPEP can fulfill your requirements for a hinge made of the highest-quality material, using the best design, for the lowest price on the market.

In addition to our wide selection of stainless steel industrial butt hinges, we also offer hinges made of aluminum, steel, and plastic, in several finishes, and with or without holes.

To make our butt hinges, we employ a team of qualified engineers and professional testers, who are intimately involved in every aspect of the manufacturing process.

If none of the products in our catalog meets your exact specifications, SPEP also offers custom designed and/or modified industrial butt hinges using high-tech design and manufacturing processes, including 3-D CAD, run on the SolidWorks platform, and finite element analysis (FEA) capability. Our fused deposition modeling (FDM) machines allow us to create a 3-dimensional ABS plastic prototype of a part within hours, which we make available to you for use in your own design process.

Our quality department runs on Oracle’s Quality Module and SPEP is ISO 9001 certified for industrial quality management.

Sierra Pacific Engineering and Products is 100% ESOP-owned, which motivates each employee to personally ensure customer satisfaction.
