Wacker Neuson 5000174831 Nylock Nut 3/8-16

The Wacker Neuson is a genuine OEM Nylock Nut 3/8-16 designed for BV35A-P and BV50A-P and BV50A-H series backpack concrete vibrators. As a factory-sourced component, part is manufactured to the exact thread pitch, diameter, and locking insert specification required for proper assembly and torque retention on these machines. Wacker Neuson genuine OEM hardware ensures the nylon locking element matches the original design intent, maintaining secure fastening under the vibration loads generated during concrete consolidation work. If you are servicing a BV-series backpack vibrator, verifying the correct hardware grade and thread specification is essential to keeping the assembly properly secured.

Key Features

• Nylon Insert Locking: — The integrated nylon insert grips the fastener thread and resists loosening caused by continuous vibration — a critical property for hardware used on concrete vibrator assemblies.
• Correct Thread Specification: — 3/8-16 UNC thread form matches the original fastener position exactly, allowing direct installation without rethreading or modification.
• Genuine OEM Sourcing: — Manufactured to Wacker Neuson specification, ensuring consistent hardness, plating, and nylon insert retention that generic hardware may not replicate.
• Broad BV-Series Compatibility: — Confirmed fitment across BV35A-P and BV50A-P and BV50A-H backpack vibrator configurations, covering both standard and EU-spec variants.
• Vibration-Environment Hardware: — Standard fasteners can back out over time on vibrating equipment; the locking nut design is specifically suited to the high-frequency operating environment of internal concrete vibrators.

A Nylock nut, also called a nylon-insert lock nut, is a standard hex nut with a nylon collar bonded into the top of the nut. When the bolt or stud is threaded through, the nylon collar deforms slightly around the thread, creating a friction-based locking action that resists vibration-induced loosening without the need for thread-locking compounds or additional hardware. On backpack concrete vibrators like the BV35A-P and BV50A series, components are subjected to sustained high-frequency vibration during operation, making vibration-resistant fasteners a functional requirement rather than a convenience. A worn, stripped, or missing lock nut can allow assemblies to loosen progressively, leading to component movement, accelerated wear, or structural failure during use.
