The Multiquip 19378 Hex Jam Nut 1/4-28 Plated is a genuine OEM fastener designed for BPX series backpack flex-shaft concrete vibrators. As a direct Multiquip OEM component, 19378 meets the original thread specification and plating standard used in production, ensuring a secure and lasting connection wherever it is installed. This nut is the correct replacement for BPX vibrator assemblies requiring a 1/4-28 fine-thread jam nut, and sourcing the genuine OEM part eliminates the guesswork of matching thread pitch and finish.
Key Features
- Fine-Thread OEM Specification — 1/4-28 thread pitch matches the original fastener spec exactly, ensuring proper thread engagement without risk of cross-threading or stripping.
- Corrosion-Resistant Plating — Plated finish provides a protective barrier against moisture and concrete residue, extending service life in demanding pour environments.
- Genuine OEM Part — Sourced directly from Multiquip, this nut carries the same quality standard as the hardware installed at the factory — no substitutions or compromises.
- Direct Fit for BPX Series Vibrators — Confirmed fitment for Multiquip BPX backpack flex-shaft concrete vibrators; installs without reworking threads or mounting hardware.
- Locks and Secures Critical Connections — Jam nut design prevents loosening under vibration, keeping assemblies tight during continuous operation on the pour.
A hex jam nut is a thin, low-profile nut used in conjunction with a standard nut or threaded fastener to lock a component firmly in place. On vibrating equipment like the BPX backpack flex-shaft vibrator, fasteners are exposed to constant mechanical vibration that can cause standard nuts to back off over time. The jam nut counters this by being tightened against a primary nut or surface, creating a clamping force that resists rotation and maintains a secure hold. When a jam nut is missing, worn, or incorrect in thread size, critical components can shift or come loose mid-operation, affecting vibrator performance and potentially causing equipment damage.
