Hex Nut for Water Jet Cutting Machine Parts – 1/4-20, Model No. 20442221-Hex-Nut-14-20.1327.3-1

Introduction, Application, Features, and Maintenance:

This component is a hex nut designed for water jet cutting systems. It is a six-sided threaded fastener with a 1/4-20 thread size, used to secure bolts, screws, or studs in machine assemblies.

Application:
Used to fasten and secure components in water jet cutting machines, such as mounting brackets, covers, guards, pump assemblies, and structural frame connections where a standard hex nut is required.

Features:

• Thread size: 1/4-20 (coarse thread).

• Hexagonal shape allows easy tightening and loosening with standard wrenches or sockets.

• Manufactured from high‑strength, corrosion‑resistant material suitable for harsh water jet environments.

• Provides reliable clamping force for secure fastening.

• Standard dimensions ensure compatibility with mating bolts and hardware.

• Low cost and easy to replace.

Maintenance:

• Regularly inspect the hex nut for signs of corrosion, thread damage, or stripping.

• Check for loosening of fastened components during routine inspection.

• Replace immediately if threads are damaged, stripped, or if the nut shows signs of deformation or corrosion.

• Use appropriate torque values as specified for the connection.

• Consider using thread‑locking compound if the nut is subject to vibration.

• Ensure mating bolt threads are clean and undamaged before installation.
