Low Profile No Slip Clip on Barrel Nuts for Tapping Screws U Type Spring Clip Nut

설명

What Are No Slip Clip on Barrel Nuts?

No Slip Clip on Barrel Nuts are specialized fasteners designed to provide a secure and vibration-resistant connection in assembly applications. They consist of a barrel-shaped nut with an integrated spring clip that prevents rotation and loosening, even under dynamic loads. These nuts are particularly useful in applications where traditional nuts may back out due to vibration, thermal cycling, or frequent disassembly.

The clip mechanism ensures that the nut stays firmly in place within a pre-punched or drilled hole, allowing for easy one-sided installation—meaning only the screw or bolt needs to be tightened from the opposite side. This makes them ideal for confined spaces or applications where access to both sides of the joint is limited.

Materials Used in No Slip Clip on Barrel Nuts

The performance and durability of No Slip Clip on Barrel Nuts depend on the material selection. Common materials include:

• Stainless Steel (Grade 304 or 316): Offers excellent corrosion resistance, making it suitable for harsh environments such as marine, chemical, or outdoor applications.

• Carbon Steel (Case-Hardened or Zinc-Plated): Provides high strength and is often used in industrial and automotive applications where cost-effectiveness is a priority.

• Brass: Used in electrical and plumbing applications due to its corrosion resistance and non-sparking properties.

• Aluminum: Lightweight and corrosion-resistant, ideal for aerospace and electronics where weight reduction is critical.

Surface Treatments for Enhanced Performance

To improve durability, corrosion resistance, and aesthetics, No Slip Clip on Barrel Nuts undergo various surface treatments:

• Zinc Plating (Yellow/Blue/Black): A cost-effective anti-corrosion coating, often with chromate passivation for added protection.

• Nickel Plating: Provides a smooth, wear-resistant finish with moderate corrosion resistance.

• Hot-Dip Galvanizing: A thick zinc coating for extreme environments, such as construction and infrastructure.

• Black Oxide: Offers a sleek appearance and mild rust resistance, commonly used in automotive and machinery.

• Phosphate Coating: Improves lubricity and corrosion resistance, often used in military and heavy machinery.

• Dacromet (Zinc Flake Coating): A high-performance coating for automotive and aerospace applications, offering superior corrosion and chemical resistance.

Key Specifications

No Slip Clip on Barrel Nuts are available in various sizes and configurations to meet different engineering requirements:

• Thread Sizes: Ranging from M3 to M12 (metric) or #4-40 to ½”-13 (imperial).

• Barrel Diameter: Typically between 6mm to 20mm, depending on the application.

• Grip Range: Accommodates material thicknesses from 1mm to 6mm.

• Retention Force: The clip design ensures a strong grip, preventing rotation even under vibration.

Success Story: High-Speed Train Interior Panel Fastening

Challenge:

A leading rail manufacturer faced persistent issues with loosening fasteners in high-speed train interiors due to constant vibration and thermal expansion. Traditional nuts and bolts required frequent re-tightening, increasing maintenance costs and downtime.

Solution:

The engineering team replaced standard fasteners with stainless steel No Slip Clip on Barrel Nuts (M6 size, Dacromet-coated) for securing ceiling panels, luggage compartments, and seat frames. The clip mechanism ensured zero rotation, while the barrel design allowed quick installation in pre-punched sheet metal holes.

Results:

• Zero Loosening Incidents: After 12 months of operation, no fastener failures were reported, even under extreme vibration.

• 40% Faster Assembly: The one-sided installation reduced labor time during manufacturing.

• Reduced Maintenance Costs: Eliminated the need for periodic re-tightening, saving thousands in service expenses.

• Enhanced Safety: Secured critical components, preventing potential hazards from loose panels.

Long-Term Impact:

The success of this application led to the adoption of No Slip Clip on Barrel Nuts across the company’s entire fleet, setting a new industry standard for reliable fastening in rail transport.

Conclusion

No Slip Clip on Barrel Nuts offer a robust, efficient, and maintenance-free fastening solution for industries where vibration resistance and reliability are paramount. Their versatility in material, coating, and sizing options makes them indispensable in modern engineering applications, from data centers to high-speed trains. By eliminating loosening and reducing assembly time, they provide both performance and cost benefits, making them a preferred choice for engineers worldwide.
