English Translation of Title:
Hex-Head Screw 14-20 x 58.1272.3-1 – Waterjet Cutting Equipment Accessory

Description, Purpose, Features, and Maintenance:

This component is a high-strength hex-head screw designed specifically for waterjet cutting systems. It is used to secure critical structural joints, pump assemblies, or abrasive delivery line connections where high clamping force and vibration resistance are required.

Purpose:

• Fastens mounting brackets, nozzle holders, or high-pressure manifold plates.

• Ensures alignment and rigidity in moving gantry or articulated arm sections.

• Provides reliable locking under continuous high-frequency waterjet pulsation.

Features:

• Manufactured from corrosion-resistant alloy steel with anti-galling treatment.

• Precision thread form (14-20 UNF) ensures consistent torque retention.

• Heat-treated for enhanced shear and tensile strength in wet, abrasive environments.

• Flanged head design distributes load evenly, reducing surface indentation.

• Compatible with standard torque wrenches and socket tools.

Maintenance:

• Inspect threads for wear, deformation, or mineral deposits after every 200 operating hours.

• Replace if thread crests show flattening or if galling occurs during removal.

• Apply anti-seize compound (water-soluble type) upon reassembly to prevent cold welding.

• Tighten to specified torque value using a calibrated wrench; do not reuse if yield torque is exceeded.

• Store in dry, oiled wrap to avoid pitting from moisture or abrasive dust.
