80 Pack 5/16"-18 Hex Nuts

Key features

• PRECISION SPECS & PERFECT FIT - Includes 80pcs of standard 5/16"-18 UNC coarse thread hex lock nuts. Precision-manufactured to fit any standard 1/2" wrench or socket perfectly, eliminating the frustration of loose threads or stripped heads.
• VIBRATION-PROOF SELF-LOCKING - Unlike standard nuts, our self-locking design prevents backing off under severe shock and high vibration—ideal for casters and moving machinery.
• SHIELD ANTI-RUST PROTECTION - Forged from premium carbon steel with a heavy-duty zinc-plated finish. This professional-grade coating provides superior resistance to rust, humidity, and corrosion, ensuring long-lasting durability in both indoor and outdoor environments.
• THE PROFESSIONAL CHOICE VS. STANDARD NUTS - While regular nuts frequently loosen over time, our lock nuts provide a secure grip that keeps your equipment safe and stable. A must-have upgrade for vehicle maintenance and industrial fleet management.
• UNIVERSAL APPLICATION RANGE - This versatile 80-pack is the go-to solution for 3"-5" caster wheels, logistics trolleys, shopping carts, home gym equipment, and wooden fence hardware. Perfect for industrial workshops and home DIY repairs.
