⚙️ 60,000 sqm smart factory — Handan, China
Every procurement manager we talk to in 2026 faces the same six headaches — do any of these sound familiar?
Raw material surcharges + freight spikes added 22% to average screw costs in 2025. Middlemen markup makes 3 inch concrete screws 40% more expensive than factory-direct.
Poorly rolled threads cause strip-out failures on job sites. A single rework due to a faulty 3 concrete screw costs $180–$350 in labor and delay penalties.
Waiting 8–12 weeks for standard 3 inch concrete screws? That’s lost revenue. Our clients report 3.5 days average downtime waiting for fastener restocks.
Missing CE, RoHS, or ICC-ES reports block project approvals. 63% of procurement teams reject suppliers who can’t provide full certification packages on day one.
New anti-dumping duties on certain Asian imports. Buyers need a supplier with diversified raw material sourcing and transparent Incoterms® 2026.
Manual PO processing adds 6–8 hours per week for your team. We offer EDI-ready ordering and real-time inventory API for seamless procurement.
From material chemistry to global logistics, every screw is engineered for zero-defect performance in the harshest environments.
Eliminate 2–3 layers of middlemen. Our 3 concrete screws start at $0.042/pc (FOB Tianjin) for volume orders of 50k+.
Case-hardened C1022 / 10B21 carbon steel with ZnNi plating — 1,200+ hrs salt spray resistance. Meets ASTM C1063 & SAE J429.
Standard 15–20 days for 3 inch concrete screws. Express 7-day air freight available for emergency orders. 98.3% on-time rate in 2025.
OEM/ODM — any length, head type (hex, flat, pan), drive (Phillips, Torx, hex), coating, and packaging. 3D CAD samples within 48h.
ISO 9001:2015 • CE • RoHS • FCC • ICC-ES (pending). We provide mill test reports and traceability docs with every batch.
From material selection → production → logistics tracking. Dedicated account manager + real-time WhatsApp support.

Structural columns, base plates, mezzanine rails — 3 inch concrete screws eliminate expansion anchor slippage.
Tractor attachments, harvester frames, irrigation supports — vibration-resistant thread design.
Engine mounts, chassis brackets, EV battery tray fastening — ZnNi 3 concrete screws with 1,200hr salt spray.
Highway guardrails, sound barriers, tunnel liners — 3 inch concrete screws with HDG coating for 50+ year service life.
The standard 3 concrete screw (C1022, case-hardened) is ideal for light-to-medium anchoring like conduit brackets or signage.
