Product Description
M8 - Thin Nyloc Hex Nuts DIN 985 - A4-80 Stainless Steel | Vital Parts - LN985-M8-A4-80
Our Thin Nyloc Hex Nuts, also known as T Type Nylon Locking Nuts, are an essential fastening solution for securing bolted connections. Designed to prevent loosening under vibrations and torque stress, these nuts provide a reliable, long-lasting grip, making them ideal for a wide range of applications, from automotive to marine engineering.
This product features a high-strength A4-80 stainless steel construction with a nylon insert that acts as a prevailing torque element. The insert provides friction against the mating threads, ensuring resistance to self-loosening.
What Are Thin Nyloc Hex Nuts?
Thin Nyloc Hex Nuts are a specialized form of self-locking nut designed with a nylon insert that deforms over the mating threads. This deformation creates a prevailing torque mechanism that increases friction and prevents unintentional loosening due to vibrations or external forces. Unlike standard hex nuts, these thin-profile variants are preferred where space and weight constraints are a concern, such as in precision engineering and lightweight assemblies.
Key Features:
- Thread Size : M8
- Thread Pitch : 1.25mm
- Across Flats : 13mm
- Height : 8mm
- Manufactured to DIN 985 standards, ensuring consistent quality and performance
- Nylon insert provides a self-locking mechanism to resist loosening
- Corrosion-resistant, making them suitable for harsh environments
- Lightweight and compact, ideal for applications with space constraints
- Available in metric sizes from M2 to M36
Applications:
Our Thin Nyloc Hex Nuts are ideal for:
- Automotive and mechanical engineering applications
- Aerospace and precision engineering industries
- Marine and offshore environments requiring corrosion resistance
- Construction and structural frameworks
- DIY projects, furniture assembly, and general fastener applications
Benefits:
- Prevents loosening caused by vibrations and dynamic loads
- Reduces the need for additional locking mechanisms, such as washers
- Provides a strong and durable hold for extended reliability
- Easy to install and remove without special tools
Thin Nyloc Hex Nuts DIN 985 are an excellent choice for applications requiring a secure, vibration-resistant fastening solution. Whether used in industrial settings, construction projects, or mechanical assemblies, these nuts offer superior durability and performance.
