1. Core Structure

Wing-Shaped Handle:

• Design: With a double-wing symmetrical form reminiscent of butterfly wings, each wing spans 10-25mm in length and 2-4mm in thickness, delivering a torque lever effect with manual torque capabilities ranging from 0.5-1.5N·m.

Surface Treatment: Enhanced with roll patterns or anti-slip protrusions to ensure a firm grip, preventing any hand slippage.

• Threaded Body:

Thread Type: Available in standard metric or imperial measurements, such as M6 and 1/4-20 UNC, with a precision rating of 6g level suitable for universal applications.

Thread Length: Ranging from 8-30mm to tailor-fit diverse application scenarios.

• Neck Transition:

• Diameter: Typically designed 0.5-1mm smaller than the larger thread diameter, preventing interference with the handle and substrate.

• Strength: Features a thickened neck design with wall thickness ≥ 1.5mm, ensuring durability and preventing breakage during tightening.

2. Materials and Craftsmanship

• Substrate Selection:

PA66+GF30%: Boasts high strength with tensile strength ≥ 80MPa, outstanding temperature resilience from -40 ºC to 120 ºC, making it ideal for outdoor equipment.

POM (Saigang): This material offers self-lubricating properties with a friction coefficient of 0.15-0.25, and minimal water absorption at 0.2%, perfect for precision instruments.

PP (Polypropylene): Known for its cost-effectiveness with prices roughly 40% lower than PA66. It's food-grade certified, widely used in household appliances.

• Molding Process:

Injection Molding: This process allows for a one-time molding with precise tolerance control of ± 0.1mm, ensuring no seam between thread and handle.

• Secondary Processing: High-end models may feature ultrasonic welding with metal inserts, such as stainless-steel threaded sleeves, to elevate wear resistance.
