Our 5/8 concrete anchor with HDG coating meets DOT specifications for barrier rails, sign structures, and bridge retrofits.

1. What is the difference between a 5/8 concrete anchor and a 5/8 x 4 concrete anchor?

The 5/8 concrete anchor refers to the diameter (5/8″), while 5/8 x 4 concrete anchor specifies both diameter and length (4″). The 4″ length is the most common for structural anchorage in concrete slabs and columns. We stock both and can customize lengths from 2″ to 12″.

2. What grades and standards do your anchors meet?

Our 5/8 concrete anchor products comply with ASTM F1554 (Gr.36, Gr.55), SAE J429 Grade 5, and ISO 898-1. We also provide anchors to DIN 976 and BS 5950 upon request. Mill certificates and 3rd-party test reports are included.

3. What is the minimum order quantity (MOQ) for 5/8 x 4 concrete anchors?

For stock sizes (5/8 x 4 concrete anchor with HDG coating), MOQ is 500 pcs. For custom lengths, coatings, or special grades, MOQ starts at 1,500 pcs. We also offer sample kits (50 pcs) for qualification at cost + shipping.

4. How do you handle shipping to the USA and Europe?

We ship via FOB Tianjin / Shanghai or CIF to major ports (Los Angeles, Rotterdam, Hamburg, etc.). Average transit: 25–35 days sea freight. For urgent orders, we offer air freight (5–7 days). We handle all customs documentation and can provide DDP (Delivered Duty Paid) terms.

5. Can you provide OEM/ODM packaging and branding?

Yes. We offer custom packaging (poly bags, cartons, wooden crates, pallets) with your logo, part numbers, and barcodes. OEM/ODM is our core strength — we have served 40+ brands in Europe and North America. Just share your spec sheet, and we’ll match it exactly.

6. What is your quality control process for 5/8 concrete anchors?

Every production lot undergoes: ✅ Dimensional inspection (thread pitch, length, diameter) · ✅ Hardness test (Rockwell) · ✅ Tensile test (UTM) · ✅ Coating thickness (magnetic gauge) · ✅ Salt spray test (corrosion resistance). We keep full traceability from raw material to final pack.
