A2/A4 Stainless Steel Self-Locking Hex Nut M6/M8/M10 Sizes for Industrial Vibration Resistance

Product Overview

Our A2/A4 Stainless Steel Self-Locking Hex Nut is engineered to withstand extreme vibrations, shocks, and dynamic loads in industrial environments. Featuring a self-locking nylon insert or prevailing torque design, these nuts maintain clamp force without loosening, even under continuous stress. Available in M6, M8, and M10 sizes and crafted from corrosion-resistant A2 (304) or A4 (316) stainless steel, they are ideal for machinery, automotive, railways, and marine applications where reliability is non-negotiable.

Key Features

✅ Self-Locking Mechanism

• Nylon Insert (Self-Locking): Nylon collar grips threads to resist loosening from vibrations (temperature range: -40°C to 120°C).
• Prevailing Torque (All-Metal): Distorted threads create friction for reusable, high-temperature applications (up to 400°C).

✅ A2/A4 Stainless Steel

• A2 (304): General-purpose corrosion resistance for indoor/outdoor industrial use.
• A4 (316): Enhanced with molybdenum for marine, chemical, and saltwater environments.

✅ Vibration-Resistant Design

• Prevents Back-Off: Eliminates need for lock washers or adhesives in high-stress assemblies.
• Durable Threads: Precision-machined threads (ISO 898-2 compliant) ensure consistent torque retention.

✅ Hex Head Compatibility

• Standard Wrench Fit: Compatible with DIN 985/982 standards for seamless integration.
• Reusable: Maintains locking performance after repeated installations (prevailing torque type).
