The Conquest 1-3/4"-5 Grade C NU Heavy Nylon Insert Locknut is engineered for securing oversized structural connections in environments where movement and vibration are expected. Designed with coarse 5 TPI threading and a nylon insert, this locknut resists loosening without the need for additional locking hardware or adhesives. The internal nylon ring grips the mating bolt threads, providing a friction-based hold that keeps assemblies tight—even under constant stress.
Manufactured from hardened Grade C carbon steel and finished plain, this locknut is built for use in clean, dry indoor settings. The heavy-pattern design offers increased bearing surface and load distribution, making it well suited for demanding industrial or structural tasks. Whether you’re anchoring equipment, framing mechanical systems, or performing maintenance in high-vibration zones, this locknut delivers long-term performance and reliability with fewer retightening cycles.
