Clinch Products

Clinch products include clinch nuts, studs, and self-clinching standoffs. These are prominent components in sheet metal fabrication since they are designed to provide strong, permanent threads in the metal sheets. They’re great to use for durability, space saving, and high-performance fastening uses.

How Clinch Fasteners Work

Clinch fasteners are installed by pressing them into pre-punched or drilled holes in sheet metal using a press. Unlike traditional fasteners that rely on tapping or threading, clinch fasteners displace the surrounding material as they’re installed, forming a secure mechanical lock. The result is a permanent, load-bearing thread in sheet metal.

Each type of clinch fastener serves a specific purpose:

• Clinch nuts provide reusable threads for mating screws and bolts.
• Clinch studs create a permanently mounted male thread for fastening.
• Self-clinching standoffs offer a fixed spacing solution, ideal for mounting panels or components.

Common Applications

Clinch fasteners are widely used in:

• Electronics enclosures
• Telecommunications equipment
• Automotive assemblies
• Medical devices
• Industrial machinery
• Aerospace panels

They’re favoured in these applications due to their low-profile design, high torque resistance, and ease of installation.

Installation Basics

Installing clinch fasteners requires a press, either manual or pneumatic/hydraulic, along with proper tooling to apply the required force. The key steps include:

1. Prepare the hole: Ensure the sheet metal has the correct hole size and material thickness according to the fastener specs.
2. Position the fastener: Place the fastener into the hole with the knurled or serrated side facing the sheet.
3. Apply force: Use a press to embed the fastener into the metal. The metal is forced into the undercut of the fastener, securing it in place.

Correct hole sizing and sheet thickness are crucial. Most manufacturers provide detailed specifications to ensure proper installation. If you need assistance obtaining this information let us know.

PEM® and Equivalent Parts

PEM® branded parts are very popular for clinch products. There are also alternative options to the brand that can be used in the same applications. If you use parts like CLS (self-clinching studs), CLN (clinch nuts), or SO (self-clinching standoffs) you can often find interchangeable parts under other brands, typically at more competitive prices.
