[100 PKG] Hex Lock Nuts NU Nylon Inserts Steel Zinc 3/8-16

Hex Lock Nuts NU Nylon Inserts Steel Zinc 3/8-16 are precision-engineered self-locking fasteners designed to keep assemblies secure in vibration-prone environments. The nylon insert creates friction that resists loosening, while the steel body with a zinc finish provides durable corrosion resistance for long-lasting performance.

• Self-locking nylon insert (NU): The nylon insert increases friction to prevent loosening under shock and vibration.
• Thread size: 3/8-16 inch standard coarse thread for wide compatibility.
• Material and finish: Steel with a zinc plating for corrosion resistance and durability.
• Hex nut design: Easy to drive or hold with standard wrenches for quick installation.
• Applications: Ideal for machinery, automotive, construction, and outdoor equipment where vibration is common.

How to use: Align the nut with a compatible 3/8-16 bolt, hand-tighten, then use a wrench to snug the nut. Do not reuse if the nylon insert is damaged or worn.

Why choose these hex lock nuts? They combine reliable self-locking performance with a durable steel zinc finish, delivering secure assemblies that stay tight even in challenging conditions.
