English Translation of Title:
Hex-Head Screw 5/8‑11 x 1‑3/4 – Waterjet Cutting Equipment Accessory (ID: 95423679)

Description, Purpose, Features, and Maintenance:

This component is a heavy‑duty hex‑head screw with a nominal diameter of 5/8 inch, 11 threads per inch (UNC), and a length of 1‑3/4 inches. It is engineered for structural fastening applications in waterjet cutting systems, particularly where high clamping loads and resistance to loosening from machine vibration are required.

Purpose:

• Secures heavy subassemblies such as cutting head supports, abrasive hopper mounts, and pump base plates.

• Provides positive locking for adjustable guide rails and gantry beam connections.

• Serves as a primary fastener in load‑bearing joints that experience dynamic forces during high‑speed traversing.

Features:

• Manufactured from high‑strength alloy steel with a protective anti‑corrosion coating suitable for humid and abrasive‑laden environments.

• Full‑body precision rolling produces consistent thread form for reliable torque retention.

• Heat‑treated to achieve enhanced tensile and yield strength, reducing risk of thread stripping under shock loads.

• Standard hex head allows easy service with common wrenches and impact sockets.

• Designed with a controlled thread run‑out to minimize stress concentration at the shank‑to‑head transition.

Maintenance:

• Visually inspect threads for wear, burrs, or corrosion before each major service interval.

• Check for signs of plastic deformation or necking after high‑torque applications; replace if elongation is detected.

• Clean threads with a stiff nylon brush to remove abrasive dust; avoid wire brushes that may damage the coating.

• Apply a light film of anti‑seize compound (compatible with waterjet seal materials) upon reassembly to prevent thread galling.

• Torque to the specified value using a calibrated wrench; do not exceed the elastic limit to preserve clamping integrity.

• Replace in sets if multiple fasteners on the same joint show similar wear patterns.
