Galvanized Hollow Lead Screw High Strength Hollow Threaded Rod Grade 4.8
Product Overview
Chamfered Threaded Tube High Strength Easy-Install Industrial Pipeline Connector designed for reliable performance in demanding industrial applications.
Basic Parameters and Structural Design
Dimensional Specifications:
Thread Type: Commonly adopts NPT (60° tapered thread) or BSPT (55° sealed tapered thread), with nominal diameters ranging from 1/8" to 2"
Chamfer Design: The tube end features a 45° chamfer (edge-cut) with a width of 1-3mm, facilitating alignment during installation and reducing burrs
Material: High-strength carbon steel (e.g., Q235) or stainless steel (304/316), surface-treated with galvanization or nickel plating for corrosion resistance
Structural Features:
Threaded Connection: Integral external threads, precision-machined to ensure tight fit with mating components (e.g., couplings, flanges)
Separable Design: Some models allow disassembling the tube body and threaded sleeve for flexible installation in confined spaces
Technical Performance
Load Capacity:
Working Pressure: Up to 1.6-2.5MPa (NPT threads) or 2.0-4.0MPa (BSPT threads), depending on material thickness
Temperature Range: -20°C to +120°C (standard), with high-temperature variants available for up to +200°C
Surface Treatment:
Zinc Plating: Thickness ≥5μm, salt spray resistance ≥24 hours
Anodizing (aluminum alloy): Hardness ≥12HV, suitable for outdoor or corrosive environments
Application Fields
Industrial Machinery: Pipe connections in hydraulic systems, pneumatic equipment, and mechanical transmission devices
Lighting Fixtures: Structural connectors in LED track lights and ceiling lamps, combining heat dissipation with mechanical fixation
The chamfered edge simplifies insertion into fittings, reducing alignment time by 30% compared to non-chamfered tubes
Compatible with standard wrenches or automated assembly tools for quick installation
Reliability:
Precision threading ensures minimal leakage (<0.01MPa pressure drop) when paired with sealing tapes or gaskets
Heat-treated materials enhance fatigue resistance, extending service life by 20% under cyclic loading
Maintenance & Installation Guidelines
Inspection:
Regularly check thread integrity for corrosion or deformation, especially in high-moisture environments
Measure chamfer wear with a caliper; replace if deviation exceeds ±0.5mm
Assembly:
Apply PTFE tape or thread sealant to tapered threads for leak-proof connections
Use torque wrenches to avoid over-tightening (recommended torque: 8-15N*m for 1/2" threads)
Storage:
Store in dry conditions, sealed with anti-rust paper or plastic caps to prevent oxidation
Typical Application Cases
LED Track Lighting: The edge-cut tooth tube (M10x1 thread) securely connects lamp heads to tracks while dissipating heat, supporting load-bearing up to 5kg
Hydraulic Systems: A 3/4" NPT tooth tube withstands 1.8MPa pressure in excavator boom joints, ensuring stable operation under impact load
