The fastening and opening of bolts and nuts adopts non-standard design, and the matching
non-standard tools are used to solve the opening and fastening problems. In general, other
wrenches cannot be inserted. in the appearance design of nuts and bolts, non-standard slotting,
opening or pentagonal, heptagonal, nine-corner or custom-made corresponding groove tools
have played a very good anti-theft effect

A lock 木の実 is a specialized nut designed to prevent loosening from vibration, torque, or other mechanical forces that might otherwise cause a standard nut to become undone. It is a critical component in industries and applications where secure fastening is essential, especially in high-vibration environments.

Types of Lock Nuts:

1. Nylon Insert Lock Nut (Nyloc Nut):

   • Features a nylon insert that grips the bolt or screw, providing friction and preventing loosening.
   • Commonly used in automotive, aerospace, and general machinery applications.

2. All-Metal Lock Nut:

   • Made entirely of metal, these lock nuts use the deformation of the metal to create friction against the fastener threads.
   • Known for their durability and ability to withstand high temperatures and harsh environments.

3. Serrated Flange Lock Nut:

   • Has a flange with serrated edges that bite into the material or the surface of the nut to increase resistance to loosening.
   • Often used in applications where higher torque is involved or when the fastener needs to be secured in softer materials like plastic or aluminum.

4. Prevailing Torque Lock Nut:

   • This design applies constant pressure to the bolt through internal features (such as a crimped portion of the nut).
   • Used in applications where the nut needs to be secure but may need to be tightened or adjusted multiple times without damaging the threads.

材料:

• Steel: Most common, providing strength and cost-effectiveness. Can be treated or coated for corrosion resistance (e.g., zinc-plated).
• Stainless Steel: For use in corrosive environments, providing higher resistance to rust and corrosion.
• Brass or Aluminum: For applications requiring lightweight materials with decent corrosion resistance.

アプリケーション:

• 自動車: In engines, suspensions, and other parts exposed to vibration and high torque, such as wheel nuts and drive shafts.
• 産業機器: Used to secure parts in machinery, preventing loosening in areas subject to constant motion and vibration.
• 航空宇宙: In aircraft and aerospace components to ensure fasteners remain securely in place during high-speed flight and extreme conditions.
• 建設: For heavy-duty fastening in structural components or machinery exposed to vibrations.

Benefits:

• Prevents Loosening: Provides a reliable and secure fastening, preventing accidental disassembly due to vibration or movement.
• Durable and Strong: Made from tough materials that can withstand heavy stress, high torque, and vibration.
• 再利用性: Many lock nuts, especially nylon insert types, can be reused several times without losing their locking ability.
• Cost-Effective Solution: Reduces the need for more expensive, specialized locking mechanisms.
• Versatility: Available in various sizes, materials, and thread types to suit different applications and environments.

Considerations:

• Temperature Sensitivity: Nylon insert lock nuts may degrade or lose effectiveness at very high temperatures (above 250°C), so alternatives like all-metal lock nuts may be required in extreme conditions.
• Space Constraints: Some lock nut designs, such as the all-metal type, can be more compact, but others like the nylon insert type may require more space.
