Product Description

The innovative Plastic Wing Nut is a remarkable tool-free fastener crafted meticulously through the state-of-the-art injection molding process, with engineering plastics forming its strong substrate. The brilliance of its core design lies in its wing-shaped handles that allow effortless manual tightening and disassembly. Designed to meet the demands of light load applications, it thrives in environments requiring non-metallic contact and swift maintenance, thanks to the lightweight, insulating, and corrosion-resistant properties of plastic. Below, we explore its features through six key dimensions: structure, performance, application, selection, advantages and disadvantages, and trends:

------



1. Core Structure

Wing-Shaped Handle:

• Shape: Exhibiting a stunning double wing symmetrical design reminiscent of butterfly wings, each single wing spans a length of 10-25mm with a thickness of 2-4mm, providing a powerful torque lever effect (enabling manual torque of 0.5-1.5N · m).

Surface Treatment: Enhanced with roll patterns and anti-slip protrusions to ensure a firm grip without slipping.

• Threaded Body:

Thread Type: Available in standard metric or imperial types (e.g., M6, 1/4-20 UNC), precision-crafted to a 6g level for universal applications.

Thread Length: Ranges from 8-30mm, tailored to meet diverse application scenarios.

• Neck Transition:

• Diameter: Typically 0.5-1mm smaller than the thread's larger diameter to ensure no interference between the handle and substrate.

• Strength: Features a fortified thickened neck design (wall thickness ≥ 1.5mm) to prevent breakage during tightening.

2. Materials and Craftsmanship

• Substrate Selection:

PA66+GF30%: Boasts high strength (tensile strength ≥ 80MPa) and temperature resistance (-40 ºC~120 ºC), making it ideal for outdoor equipment.

POM (Saigang): Offers self-lubrication (friction coefficient 0.15-0.25) and low water absorption (0.2%), perfect for precision instruments.

PP (Polypropylene): Cost-effective (around 40% cheaper than PA66) and food grade certified, perfect for household appliances.

• Molding Process:

Injection Molding: Achieves seamless one-time molding with precise tolerance control of ± 0.1mm, ensuring no seam between thread and handle.

• Secondary Processing: Certain premium models feature ultrasonic welding with metal inserts (e.g., stainless steel threaded sleeves) to boost wear resistance.
