Clip Nut — Product Introduction
The clip nut, also known as spring nut, card-style nut, U-clip nut, or edge clinch nut, is a fastener that uses an elastic clip to engage the edge of a thin plate, a pre-punched hole, or a profile groove. During installation, no welding, pre-tapping, or access from the opposite side of the plate is required; simply snap the nut into the plate edge or mounting hole, and a reliable internal thread connection point is established. Clip nuts are typically made of spring steel or stainless steel, offering excellent elasticity and clamping force, with surface treatments such as zinc plating, nickel plating, black oxide, or Dacromet available. They are widely used in automobiles, sheet metal cabinets, household appliances, electronic equipment, and various thin-plate structures.
I. Product Features
-
Elastic clamping, quick installation: The nut features an elastic clip that snaps quickly into the plate edge or hole, requiring no welding, riveting, or tapping, and offering high installation efficiency.
-
Single-sided installation, suitable for enclosed structures: Operation from only one side of the plate is needed, making it especially suitable for square tubes, round tubes, profiles, enclosures, and other situations where two-sided access is impossible.
-
Rotation- and loosening-resistant, reliable connection: The clip forms an elastic clamp with the plate edge or hole wall, effectively preventing the nut from spinning during bolt installation and improving connection stability.
-
Adaptable to different plate thicknesses: Through elastic deformation of the clip, stable clamping is maintained within a certain plate thickness range, offering good versatility.
-
Diverse materials and surface treatments: Common materials include spring steel and stainless steel; surface treatments such as zinc plating, nickel plating, black oxide, and Dacromet are available to meet rust prevention and appearance requirements.
-
Repeated assembly and disassembly: Under proper use conditions, bolts can be threaded in and out multiple times; the nut is not prone to falling off or damage, facilitating maintenance and replacement.
II. Product Advantages
-
High installation efficiency and low comprehensive cost: No welding or pre-tapping is required, reducing processing steps and labor costs, making it suitable for batch production and on-site construction.
-
No damage to the plate surface: The installation process involves no heat input or welding distortion, preserving pre-coated plates, galvanized plates, and spray-finished surfaces.
-
Suitable for enclosed or semi-enclosed structures: Single-sided installation is sufficient, especially for tubes, profiles, enclosures, and other locations that are difficult to access from the other side.
-
Excellent rotation resistance: The elastic clip locks onto the plate, effectively preventing nut rotation, making it suitable for frequent assembly/disassembly or vibrating environments.
-
Strong versatility: Adaptable to different plate thicknesses and various mounting hole shapes, widely used in all kinds of sheet metal connections.
-
Vibration- and loosening-resistant: The elastic structure absorbs part of the vibration, maintaining clamping force and keeping the connection secure.
