Product Description

Eye Bolt High Strength Forged Lifting Bolt for Industrial Projects

Forged high-strength Eye Bolts manufactured in accordance with DIN 580 standard are made from premium carbon steel or stainless steel to ensure reliable load capacity and safe lifting performance. Precision machined metric threads provide smooth installation and secure tightening during hoisting operations.

Available with zinc plated, black oxide, or plain surface finish for enhanced corrosion resistance in various industrial environments. Designed mainly for vertical lifting applications, widely used in machinery, steel structures, construction, marine, oil & gas, and EPC projects.

Quality Control & Certifications

Quality control is applied throughout the entire production process. From raw material inspection to in-process checks and final inspection before shipment, defined procedures ensure dimensional accuracy, mechanical performance, and product consistency. Material traceability by heat number and mechanical testing are standard practices.

Production & Testing Equipment

Comprehensive production facilities include forming, machining, heat treatment, and surface treatment processes. Professional testing equipment is used for tensile strength, hardness, thread inspection, and dimensional checks to support technical verification and project documentation.

Packaging & Logistics

Products are packed according to characteristics and customer requirements. Common methods include cartons, wooden cases, and pallets. Flexible export solutions support various delivery terms and logistics arrangements for international shipments.

Frequently Asked Questions

Can you produce customized fasteners based on drawings?

Yes. We support customized production based on drawings (PDF/DWG/STEP), samples, or specific technical requirements, confirming the process route and providing detailed quotations.

What information is needed for an accurate quotation?

Please provide the product type, standard (ASTM/DIN/ISO), size (diameter x length), material grade, surface treatment, and quantity to ensure a fast and precise response.

What materials are available for these fasteners?

We offer fasteners in stainless steel, carbon steel, alloy steel, aluminum alloy, copper, and other special alloys based on your project's strength and corrosion requirements.

What surface treatments can be provided?

Available treatments include zinc plating, hot dip galvanizing (HDG), black oxide, phosphate coating, and other customized finishes to meet specific corrosion resistance needs.

Do you provide samples before mass production?

Yes. Samples can be provided for confirmation. Standard items are usually available quickly, while customized items are arranged after confirming technical specifications.

How is product quality controlled?

Quality is maintained through raw material verification, in-process inspection during forming and machining, and a final rigorous check before packing and shipment.
