Product Overview
The 114850 Large-Flange Hex Nut is a genuine OEM nut from Graco featuring a built-in wide flange that acts like an integrated washer — distributing load and preventing damage to housing or cover surfaces under bolt/nut compression. Its durable construction (often stainless or corrosion-resistant) makes it suitable for demanding pump and fluid-handling environments where vibration or pressure stresses exist.
Key features include:
- Large flange base distributes load and protects mounted surfaces (instead of separate washer).
- OEM-specified nut — ensures correct dimensions, thread, and compatibility with Graco assemblies.
- Corrosion-resistant / durable material (as per supplier listing) — suitable for fluid-handling, pump housings, and industrial applications.
Why Use This Nut?
Using the OEM-specified 114850 Nut, Large-Flange Hex ensures that your equipment maintains factory-intended fastening integrity — with proper load distribution and sealing — especially under pressure, vibration or repeated maintenance cycles. Substituting with generic nuts may compromise sealing, cause uneven load on housings, or lead to premature wear or leaks.
