What We Can Manufacture
We manufacture custom sheet metal parts with self-clinching PEM studs, built entirely to your technical requirements.
Whether you need a single prototype bracket or a production run of 10,000 enclosures, every part starts with your drawing and is delivered as a finished, assembly-ready component.
Because self-clinching fastener installation is completed in-house, you get a true one-stop manufacturing solution.
There is no need to outsource fastener installation, coordinate multiple suppliers, or manage quality issues caused by separating sheet metal fabrication from hardware installation.
Custom brackets, mounting panels, and enclosure components delivered with self-clinching studs and standoffs already installed.
How Self-Clinching Studs Work
Self-clinching studs are installed by pressing them into precisely prepared mounting holes in sheet metal.
A controlled press installs the self-clinching stud into a precisely prepared mounting hole.
During installation, the fastener’s knurled or serrated clinching section displaces and embeds itself into the surrounding sheet material, creating a permanent mechanical lock.
The clinching section of the stud displaces the surrounding sheet material to create a permanent mechanical lock.
The entire process requires:
No welding, no heat-affected zone, and no heat distortion in the surrounding sheet metal.
The stud is securely installed while the reverse side of the sheet remains flat and free from weld distortion.
This provides three major advantages:
- A flush reverse side. The opposite side of the panel remains essentially flush, which is especially important for enclosures, racks, and mounting panels that need to sit flat against walls, rails, or other components.
- More consistent mechanical strength. Self-clinching studs provide stable and repeatable pushout and torque-out performance in volume production, without the operator-dependent variability often associated with welded studs.
- No post-weld finishing. There is no weld spatter to grind, no heat discoloration to remove, and no need to straighten sheet metal distorted by welding.
For applications that require threaded mounting points in thin sheet metal — such as server racks, control cabinets, telecommunications enclosures, and medical equipment frames — self-clinching fasteners are a widely used and highly effective solution.
Typical Applications
- Server Racks and Data Cabinets — Threaded studs for mounting rails, cable-management components, and equipment trays
- Electrical Enclosures and Control Panels — Fastening points for DIN rails, terminal blocks, and internal components
- Telecommunications Enclosures — High-density self-clinching fastener layouts for PCB support and grounding / shielding connections
- Medical Equipment Frames — Suitable for precision assemblies that require repeated removal and reassembly
- LED Lighting Assemblies — Mounting points for drivers and heat sinks inside thin-sheet housings
- Industrial Automation Equipment — Brackets and mounting plates with captive fasteners for sensors, actuators, and other components
Self-clinching fasteners provide permanent mounting points in server, electrical, telecom, medical, lighting, and automation equipment.
