Nuts Spec Table
Nuts pair with bolts to secure clamping force. Hex nuts are the most versatile; nylon lock nuts and flange nuts prevent loosening in high-vibration environments. Wing nuts allow tool-free removal — convenient for parts that require frequent access. Match the strength grade and material to the mating bolt.

Frequently Asked Questions
Can nylon insert lock nuts be reused?
Nylon insert lock nuts can be reused 3–5 times, but locking effectiveness decreases as the nylon wears. New nuts are recommended for critical joints.
Should nut and bolt strength grades match?
Yes, nuts must be equal to or stronger than the bolt. Use grade 8 or higher nuts with grade 8.8 bolts to prevent failure.
Do you still need a washer with a flange nut?
Flange nuts provide a wide bearing surface so a separate washer is generally unnecessary. However, a washer may still be added for soft materials or special sealing requirements.
