Hexagon flange metal lock nuts are specialized fasteners designed to provide a secure, vibration-resistant connection in mechanical assemblies. Here’s a detailed description:

主要功能：

1. Hexagonal Head – Features a six-sided (hex) head for easy tightening/loosening with standard wrenches or sockets.

2. Integrated Flange – The built-in flange distributes clamping pressure over a wider surface area, reducing the risk of damage to the connected material and improving joint stability.

3. 鎖定裝置 – Typically includes a nylon insert (metal insert or deformed threads) that creates friction against the bolt, preventing loosening due to vibrations or dynamic loads. Hexagon flange metal lock nut

4. 材質 – Commonly made from steel (carbon or stainless), brass, or other metals, often with corrosion-resistant coatings like zinc plating or black oxide.

5. 線路類型 – Available in metric (M) or imperial (UNC/UNF) thread sizes to match corresponding bolts/screws.

優勢：

• 抗震性 – Ideal for automotive, machinery, and aerospace applications where movement could loosen standard nuts.

• Eliminates Need for Washers – The flange acts as a built-in washer, simplifying assembly.

• Stronger Grip – The locking feature ensures long-term fastener integrity.

常見應用：

• Automotive components (engine parts, suspension systems)

• Industrial machinery

• Electrical enclosures

• Construction and structural assemblies

Variants:

• Nylon Insert Lock Nuts – Have a polymer ring for elasticity and grip.

• All-Metal Lock Nuts – Use deformed threads or slots for a metal-to-metal locking action.

• Serrated Flange Nuts – Feature teeth under the flange to bite into surfaces for added resistance.
