Spring Nut

Spring Nuts – Speed Nut & Clip Nut Manufacturer & Supplier in UAE

Asia Bolts Industries LLC is a specialist Spring Nut manufacturer and supplier based in Dubai, UAE, delivering precision-stamped spring fastening solutions to the automotive, electrical, HVAC, construction, oil & gas, and marine sectors across the GCC and global markets since 1997. Our spring nuts are engineered for fast, reliable, and vibration-resistant fastening in applications where conventional hex nuts cannot be used — particularly in thin sheet metal assemblies, blind access panels, and high-speed production line installations.

What Are Spring Nuts?

Spring Nuts are single-piece, spring-action fastening elements stamped from hardened strip steel. They grip onto a panel edge, slot, or bolt thread by spring tension alone — requiring no tools, no welding, and no rear access for installation. Once engaged, the spring force of the nut resists vibration-induced loosening, making them a preferred fastening solution in dynamic, high-cycle applications.

They are commonly known by several names depending on configuration and industry:

• Speed Nuts — U-shaped clip that snaps over a panel edge with an integral threaded hole
• Clip Nuts / U-Nuts — clips onto a panel flange, accepts a bolt from the front face only
• J-Nuts — J-shaped spring clip for T-slots and extruded profiles
• Push-On Nuts — pushes directly onto a plain stud or bolt thread without rotation
• Spire / Palnut — multi-finger push-on nut for light-duty retention
• Sheet Metal Nuts — general term for stamped spring nuts used in panel assemblies

Spring Nuts are widely used in:

• Electrical enclosures and control panels — cable management, busbar supports, DIN rail mounting
• HVAC and air handling units — ductwork assembly, filter frames, access panels
• Automotive bodywork and trim — interior panels, door linings, under-bonnet assemblies
• Telecommunications and data centre equipment — rack mounting, server enclosures, cable trays
• Marine and offshore equipment panels — junction boxes, instrument housings, switchgear
• Construction and modular buildings — cladding systems, suspended ceilings, partition walls
• Oil & gas instrument enclosures — field junction boxes, analyser shelters, control buildings

Types of Spring Nuts Available

1. U-Nut (Clip Nut) — DIN 7967 variant
A U-shaped spring clip with an integral threaded tab. Clips onto a panel flange of defined thickness range. The bolt is inserted from the front face, engaging the threaded tab on the spring arm. Widely used in electrical enclosure assembly and automotive panel fastening.

2. Speed Nut (Tinnerman Nut)
A flat stamped spring nut with a pierced thread form. Snaps over a panel edge or into a slot. Accepts self-tapping or machine screws. Standard for high-volume sheet metal assembly in HVAC, automotive, and appliance manufacturing.

3. J-Nut
A J-shaped clip that hooks into a rectangular slot or T-profile channel. The bolt engages a threaded tab on the spring arm. Used extensively in automotive body assembly and modular structural profiles.

4. Push-On Nut (Spire Nut / Palnut)
A multi-finger stamped nut that pushes axially onto a plain or threaded stud, gripping by spring finger contact. Used for light retention, cable management clips, and trim fastening where removal is not anticipated.

5. Flat Push-On Nut
A flat washer-form nut with a central pierced thread that pushes onto a stud. Provides a wider bearing surface than a spire nut. Common in appliance and electrical panel assembly.

6. Extended Spring Nut (Long Clip Nut)
An extended U-nut body accommodating wider panel flange widths or providing a larger spring retention force. Used in heavy-gauge panel assemblies and industrial enclosures.
