DIN975 Full Thread Rod 4.8 8.8 Grade Zinc Plate Threaded Rods Bar

Meta Description

High-quality DIN975 full thread rod in Grade 4.8 and Grade 8.8, zinc plated anti-rust finish. Metric coarse threaded bar for construction suspension, HVAC and mechanical fastening. Custom length & bulk OEM supply available.

1. Product Overview

Our DIN975 full thread rod, also named an all-threaded bar, is manufactured strictly in accordance with German DIN 975 industrial standards. We supply two mainstream carbon steel strength grades: Grade 4.8 and Grade 8.8, with standard electric zinc-plated surface treatment for indoor and mild outdoor corrosion resistance. Unlike headed bolts, this headless continuous threaded bar features full-length metric coarse threads with 6g external thread tolerance, ensuring seamless matching with standard DIN nuts and flat washers.

As one of the most widely used general fasteners in European and global industrial markets, DIN975 threaded rods replace customised bolt assemblies for long-distance connection, suspension and structural anchoring. All rods are supplied in stock lengths of 1m, 2m and 3m, and support free cutting to non-standard sizes for on-site installation demands.

2. Core Product Specifications

Standard Compliance: DIN 975 (equivalent to ISO 4032 matching standard, compatible with GB/T 15389)

Strength Grade Classification

• Grade 4.8 Zinc Plated Threaded Rod: Made of low-carbon Q235 steel without heat treatment. Tensile strength reaches 400MPa, low hardness for easy cutting, bending and secondary processing. It is the cost-effective option for static light-load fastening scenarios. The zinc coating thickness is 5-8μm, providing 6-12 months of indoor anti-rust performance.

• Grade 8.8 Zinc Plated Threaded Rod: Made of medium-carbon 45# steel with quenching and tempering heat treatment. Minimum tensile strength up to 800MPa, excellent anti-fatigue and shock resistance. Ideal for dynamic load, vibration and heavy structural connections. Zinc coating thickness is 8-12μm for enhanced moisture resistance in humid indoor environments.

Thread & Size Range: Right-hand metric coarse thread, mainstream diameters M6-M36. Stock hot-selling sizes: M8, M10, M12, M16, M20. The thread surface adopts rolling forming technology, no burrs, high thread engagement rate to avoid nut slipping.

Surface Treatment Options: Standard blue-white zinc plating; optional yellow zinc plating for better acid and alkali resistance. A hot-dip galvanised finish is available for heavy outdoor corrosion scenarios on request.

3. Key Advantages for Buyer Selection

1. Strict DIN 975 Dimensional Consistency: Every batch is inspected by thread gauges and dimensional callipers to eliminate thread mismatch, solving the common problem of poor matching between generic threaded rods and European standard fasteners.

2. Uniform Zinc Plating & No White Rust: Adopt acid pickling passivation process before galvanisation, avoiding coating peeling and early white rust in closed storage environments, reducing buyer after-sales return risks.

3. Bulk Stock & Fast Lead Time: Complete inventory of Grade 4.8 and 8.8 DIN975 threaded bars. Small MOQ for sample orders and full-container bulk export, delivery within 3-7 working days for stock goods.

4. Custom Processing Support: Provide end cutting, chamfering, thread trimming and custom packaging according to customer requirements, meeting Amazon warehouse, local distributor and engineering project procurement standards.

4. Widely Used Application Scenarios

DIN975 zinc-plated full-thread rods are universal fasteners across multiple industries, covering high-frequency search scenarios for Google users:

• Building construction: Ceiling suspension threaded rod, formwork tie rod, curtain wall structural anchoring, floor support connection

• HVAC & plumbing: Air duct hanger fixing, water pipe bracket installation, fire protection pipeline suspension

• Mechanical engineering: Equipment base levelling, conveyor bracket assembly, and industrial enclosure connection

• Electrical installation: Cable tray fixing, distribution box wall mounting, and connection

5. FAQ for Google User Intent Optimisation

Q1: What is the difference between DIN975 and DIN976 threaded rods?

DIN975 refers to a full-length threaded bar with both ends flat, while DIN976 is a double-ended threaded stud with an unthreaded middle section. DIN975 is more popular for flexible cutting and multi-scene suspension use.

Q2: Can a Grade 4.8 threaded rod be used outdoors?

Standard zinc-plated Grade 4.8 rod is only suitable for dry outdoor sheltered areas. For open, rainy outdoor environments, please choose Grade 8.8 hot-dip galvanised DIN975 threaded rods.

Q3: What is the standard length of DIN975 all-thread rod?

Global standard stock lengths are 1000mm, 2000mm, and 3000mm. We can cut to any custom length without extra processing fees for bulk orders.

6. Export Packaging & Shipping

Standard packaging: Plastic inner bag + carton outer packaging, fixed with strapping to prevent thread friction damage during sea transportation. Shipping ports include Ningbo, Zhoushan, and Shanghai, supporting FOB, CIF, and DDP international trade terms. All products provide factory inspection reports and material certificates for European customs clearance.
