Product Overview

Threaded rods (also called all-thread rods or stud bolts) are integral fasteners featuring continuous external threads along their entire length. Compliant with international and national standards such as DIN 975, ISO 898-1, and GB/T 15389, they are designed for modular connection, fastening, or hanging applications. By pairing with nuts, washers, or other threaded components, they enable adjustable and detachable assemblies. Widely used in construction, machinery, electrical equipment, and industrial installations, they excel in scenarios requiring long-span fastening, position adjustment, or heavy-load bearing.

Key Specifications

Raw Materials

Carbon steel (Q235, 35K, 45#): Cost-effective for general loads and dry environments;

Alloy steel (40Cr, 42CrMo): High strength and fatigue resistance, suitable for high-load or precision assemblies;

Stainless steel (304/A2, 316/A4): Corrosion-resistant, ideal for humid, acid-alkaline, or high-purity environments;

Non-ferrous metals (brass, aluminum alloy): Lightweight, conductive, or corrosion-resistant, for specialized electronic/architectural applications.

Surface Treatments
Plain, zinc plated, black oxide, hot-dip galvanizing (H.D.G), Dacromet, phosphating, nickel plated.

Specification Range

Metric: Diameter M3–M64, length 100mm–3000mm (customizable for longer lengths);
Imperial: Diameter 1/4"–2", length 4"–120" (compatible with imperial nuts and washers);
Thread types: Coarse thread (UNC/metric coarse) and fine thread (UNF/metric fine), based on application requirements.

Performance Grades

Carbon steel:

4.8, 8.8 (meets general load demands);

Alloy steel:

10.9, 12.9 (high-strength grades for heavy-load or vibration-prone scenarios);

Stainless steel:

A2-70, A4-70 (corrosion-resistant grades with balanced strength).

Core Characteristics

Full-thread design: Enables flexible adjustment of nut positions for precise assembly and leveling;

Strong load-bearing capacity: Continuous thread structure ensures uniform force distribution, suitable for tension and compression loads;

Versatile assembly: Compatible with various nuts, washers, and connectors for diverse installation needs;

Easy customization: Cuttable to arbitrary lengths on-site, adapting to irregular installation spaces;

Detachable and reusable: Facilitates maintenance, replacement, and modification of assemblies.

Application Fields

Construction & Infrastructure: Steel structure connections, suspended ceiling installations, pipeline fixing, and concrete formwork fastening;
Machinery Manufacturing: Equipment framing, adjustable supports, gearbox assemblies, and modular component connections;
Electrical & Electronics: Power distribution cabinet mounting, cable tray suspension, and instrument bracket fixing;
Industrial Installations: Factory pipeline supports, heavy machinery anchoring, and workshop fixture assembly;
Architectural Decoration: Curtain wall fixing, lighting bracket suspension, and furniture modular assembly.

Usage Precautions

Matching components: Use nuts and washers of the same grade/material (e.g., 12.9-grade rod with 12.9-grade nut) to ensure connection reliability;
Material/coating selection: Choose stainless steel (316/A4) or Dacromet for humid/corrosive environments; hot-dip galvanizing for outdoor construction;
Installation: Add flat washers to distribute load and protect surfaces; use spring washers or lock nuts for anti-loosening in vibration scenarios;
Avoid over-tightening: Prevent thread damage or rod deformation; control torque based on performance grade;
Regular inspection: Check for thread wear, corrosion, or bending; replace if threads are stripped or structural damage occurs.

Sales & Logistics

Markets:

North America, Europe, Asia-Pacific, and global industrial hubs;

Packaging:

Small bags, cartons, pallets (customizable packaging available);

Orders:

Accepts bulk and small-batch purchases; delivery terms negotiable.

Quality Assurance

ISO9001:2015 certified; all products undergo thread accuracy, dimensional tolerance, tensile strength, and corrosion resistance testing;
Provides long-term quality guarantees and technical support for installation and matching.

FAQ: Key Differences from Bolts

Aspect	Threaded Rods	Bolts
Structure	Full-length external threads, no fixed head	Threaded at one end, with fixed head (hex, socket, etc.)
Core Function	Adjustable connection, positioning, suspension	Fixed fastening between components (non-adjustable after installation)
Assembly Mode	Requires nuts/washers for fastening; position-adjustable	Directly screwed into threaded holes or paired with nuts (fixed position)
Application Scenarios	Long-span connection, leveling, suspension, heavy-load bearing	Component integration, fixed assembly, general-purpose fastening
Length Flexibility	Customizable/cuttable on-site	Fixed standard lengths (limited customization)
