The Unifix Class 8 Nylon Insert Nuts (DIN 982) are designed for engineers, mechanics, and DIY enthusiasts who require secure, vibration-resistant fastening for their projects. By incorporating a specialized nylon insert, these nuts provide a superior friction lock that prevents accidental loosening under dynamic conditions, making them ideal for automotive and machinery maintenance. However, it is important to note that the nylon insert is typically intended for single-use applications, as the locking effectiveness diminishes after the nut has been removed and reinstalled multiple times.

Generally, no. The nylon insert deforms during the first installation. While it may still grip, it is recommended to use a fresh nut for safety-critical applications.
No. The nylon insert is a plastic material and can melt or lose its elasticity in high-heat environments like engine blocks or exhaust manifolds.
Class 8 refers to the property class of the steel, indicating a specific level of tensile strength and proof load capacity.
The Bright Zinc Plated finish provides moderate corrosion resistance. They are suitable for sheltered outdoor use, but not recommended for saltwater or highly humid marine environments.
These specific nuts have a standard metric pitch of 1.00mm.
The nylon insert creates resistance by design. Ensure the bolt thread is clean and the pitch (M6 x 1.00) matches correctly.
This indicates the nylon insert has been damaged or the bolt is undersized. Replace the nut to ensure structural integrity.
To install these nuts, thread them onto a compatible M6 x 1.00 bolt by hand until the nylon insert makes contact. Once contact is made, use a standard wrench or socket to drive the nut into the final position.
Compatibility Note: These are designed for use with standard steel bolts. Avoid using them with damaged or rusted bolt threads, as this may strip the nylon insert during installation.
Care: While the bright zinc plating offers decent protection, avoid using harsh acidic cleaners that can strip the finish and accelerate oxidation. If the assembly is exposed to harsh elements, consider applying a light coating of anti-seize or silicone-based lubricant to the threads before installation.
