Keep your cooling equipment running smoothly and safely with our Big Size Fan Nut Lock. This essential replacement part is specifically designed to tighten and secure the fan blade onto the motor spindle, preventing dangerous slips or imbalances during high-speed operation. Crafted from reinforced, high-impact plastic, this "Big Size" variant offers a larger surface area for a more secure grip, making it a perfect fit for larger 16" and 18" fan models.
Heavy-Duty Locking: Provides a firm, vibration-resistant hold to ensure your fan blade stays perfectly centered and secure.
Big Size Universal Fit: Designed with a larger outer diameter and standard internal threading to accommodate a wide variety of domestic and industrial fan brands.

Safety First: A critical component to replace immediately if your current nut is cracked, stripped, or lost to prevent mechanical failure.

How do I know if I need the "Big" or "Small" size?
The Big size is typically used for fans with larger blades ($16"$ or higher) and has a wider outer diameter for easier hand-turning. If your current nut looks significantly smaller than the central hub of your fan blade, you may need the small version.
Does this nut tighten clockwise or counter-clockwise?
Most fan blade nuts use a Reverse Thread (Left-Hand Thread)—meaning you turn it counter-clockwise to tighten it—to prevent it from spinning off while the fan is running.
Is this durable enough for industrial fans?
Yes, our Big Size Nut is made from reinforced plastic specifically to handle the higher centrifugal forces found in larger household and light industrial fans.
