DIN 975 Threaded Rods

Key Features & Benefits

Continuous Full-Thread Design: Unlike partially threaded studs, our DIN 975 rods feature threads running the entire length . This enables:

√ Infinite Adjustability: Nuts can be positioned at any point along the rod

√ On-Site Customization: Cut to exact length required with standard cutting tools

√ Maximum Engagement: Full thread engagement with mating nuts for optimal load distribution

√ No Waste: Purchase standard lengths and use only what you need

Exceptional Versatility: The all-thread design serves multiple functions :

√ Connecting Element: Join two or more components using nuts at both ends

√ Suspension System: Ideal for hanging pipes, ducts, ceilings, and equipment

√ Anchoring Solution: Embed in concrete with appropriate anchors for structural ties

√ Adjustable Support: Create leveling feet, adjustable braces, and tensioning systems

√ Repair & Maintenance: Replace broken bolts, create custom-length fasteners on demand

Superior Load-Bearing Capacity: The continuous thread profile ensures uniform stress distribution along the entire rod length, eliminating weak points and providing predictable mechanical performance under tension and shear loads .

Multiple Material & Strength Options: Available in a comprehensive range of materials and property classes to match any application requirement :

√ Carbon Steel: Grades 4.8 (light-duty), 8.8 (medium-duty), and 10.9/12.9 (heavy-duty)

√ Stainless Steel: A2-70 (304), A4-80 (316) for superior corrosion resistance

√ Specialty Materials: Left-hand thread options, non-ferrous materials upon request

Corrosion-Resistant Finishes: Choose from various surface treatments to match environmental conditions :

√ Electro-Zinc Plated (blue/white/yellow)

√ Hot-Dip Galvanized (HDG) for heavy-duty outdoor use

√ Plain/Bright (uncoated) for indoor applications

√ Geomet® / Dacromet® for enhanced corrosion protection

√ Stainless Steel (no additional coating required)

DIN 975 Standard Compliance: Manufactured strictly to DIN 975 dimensional specifications, ensuring:

√ Precise Thread Geometry: Consistent fit with standard metric nuts and washers

√ Interchangeability: Compatible with components from any compliant manufacturer

√ Quality Assurance: Predictable mechanical properties and performance 

Extended Length Options: Available in standard lengths of 1m, 2m, and 3m, with custom lengths up to 6m available upon request .

Cost-Effective Solution: Reduce inventory complexity by stocking standard lengths that can be cut to size as needed, eliminating the need to stock multiple pre-cut lengths.

Installation Guidelines & Best Practices

1. Selection & Preparation:

√ Choose the correct diameter, material, and property class for your specific load requirements

√ Select appropriate length based on application needs (allow for nut engagement and any required thread protrusion)

√ Inspect rods for thread damage or contamination before installation

√ Clean threads if necessary to ensure smooth nut engagement

2. Cutting to Length (If Required):

√ Use appropriate cutting tools: hacksaw, angle grinder with cutting wheel, or band saw

√ Deburr cut ends with a file or grinding wheel to prevent thread damage and injury

√ Apply anti-seize compound to cut threads if necessary (especially with stainless steel)

3. Assembly:

√ Always use properly graded nuts and washers compatible with the rod material and property class

√ For load-bearing applications, ensure minimum thread engagement of at least 1.5 × diameter

√ Use two wrenches when tightening—one to hold the rod (if not fixed) and one to turn the nut

√ Apply recommended torque values based on thread size, material grade, and lubrication condition

4. Multiple Nut Applications:

√ For locking applications, use a primary nut and a secondary jam nut (thin nut) tightened against it

√ For suspension systems, use a top nut above the support point and a bottom nut below

√ For tensioning systems, consider using two nuts locked together at each end

5. Environmental Considerations:

√ Select appropriate materials/finishes for the service environment

√ Avoid mixing dissimilar metals to prevent galvanic corrosion

√ In corrosive environments, consider stainless steel or appropriate protective coatings

√ For high-temperature applications, consult engineering data for material derating factors

6. Safety Precautions:

√ Always wear appropriate PPE when cutting or installing threaded rods

√ Never exceed rated load capacities

√ For critical applications, have designs reviewed by a qualified engineer

√ Inspect installed rods periodically in safety-critical applications
