Angle Nuts

Angle Nuts

PSM Angle Nuts are spring steel fasteners designed to provide a right-angled, captive threaded attachment by leveraging the edge of a panel. They allow one component to attach perpendicularly to another without the need for extra brackets or hardware. This makes them ideal where space, cost, or aesthetics limit the use of conventional nut and bolt assemblies.

Advantages

  • Faster assembly
  • Provides fixings for differing materials
  • Low cost

Material

CS60, CS70 carbon steel

Method of Assembly

Screw fastener to panel and bring leading edge of “panel for assembly” under returned edge of fastener, for a vibration proof, right angled fixing.

When specifying, please state:

  1. Quantity
  2. Prefix (CBAN)
  3. Part No.
  4. Finish code (e.g. 6000 CBAN-0308-13)

Key Features

  1. Fast and simple assembly, attach the nut to the panel, then secure the mating part under the nut’s returned edge with a screw.
  2. Compatible with a wide range of materials, allowing mixed-metal or composite assemblies.
  3. Low-cost solution that replaces more complex welded or bracketed joints.
  4. Vibration-resistant design—spring tension maintains clamping pressure and prevents loosening.
  5. Compact configuration, providing reliable 90-degree fixings without additional clips or components.

Applications & Use Cases

Angle Nuts are used when components need to be mounted at 90 degrees without welding or using bulky brackets. They are common in enclosures, structural frames, and sheet metal assemblies where space is limited but a strong, removable fixing is required. The spring action of the nut allows for secure retention and minor flexibility under vibration, making it well suited for applications in automotive, appliance, and industrial equipment assemblies. Angle Nuts deliver an efficient, durable, and low-maintenance fastening option for engineers seeking to simplify perpendicular connections in sheet metal or lightweight assemblies.

Frequently Asked Questions About Angle Nuts

What are Angle Nuts and what are they used for?

PSM Angle Nuts work in two simple steps. First, the angle nut is screw-fastened to the primary panel. Then the leading edge of the mating component (the “panel for assembly”) is brought under the returned edge of the fastener. A screw is then driven through the mating component and into the threaded portion of the angle nut, creating a vibration-proof, right-angled fixing. The spring tension inherent in the fastener’s body maintains clamping pressure and prevents loosening under vibration — no additional lock washer or adhesive is needed.
PSM Angle Nuts are manufactured from CS60 and CS70 high-carbon spring steel. These grades are selected for their combination of hardness, resilience, and spring-back properties, which allow the fastener to maintain consistent clamping force and vibration resistance throughout the service life of the assembly. The spring steel body also provides the right-angle geometry with sufficient stiffness to withstand assembly and in-service loads.
Angle Nuts offer several advantages over welded or bracketed perpendicular joints. They enable significantly faster assembly — no welding setup, cooldown time, or post-weld finishing is required. They are removable and reusable, allowing easy disassembly for maintenance or repair. They are compatible with a wide range of materials, including mixed-metal and composite assemblies, where welding may not be feasible. They are also a low-cost solution that eliminates the need for additional components such as separate angle brackets, reducing both part count and assembly time.
Yes. PSM Angle Nuts are designed with inherent vibration resistance. The spring steel construction maintains clamping pressure on the mating component, and the returned edge geometry creates a mechanical lock that prevents loosening under vibration or cyclic loading. This makes them suitable for automotive, appliance, and industrial equipment applications where assemblies are subject to ongoing vibration or movement.
PSM Angle Nuts (CBAN) are designed specifically for perpendicular or right-angled joints — they attach to one panel and receive the mating panel at 90 degrees, providing both vertical and horizontal retention. PSM U-type Nuts (CBUN) are edge-clipping fasteners that slide over the flange or edge of a single panel to provide a captive threaded point for a screw fastened from the same plane — they do not inherently create a perpendicular joint. Choose angle nuts where a true 90-degree, bracket-free connection between two panels is required; choose U-type nuts where a single-sided, edge-positioned threaded point on a flat panel is needed.
