Overview
Lag screws, also known as lag bolts or lag wood screws, are heavy-duty fasteners designed for high-strength wood-to-wood and wood-to-structure applications. Featuring coarse threads and a hex head for wrench installation, lag screws provide exceptional holding power in structural assemblies.
Offshore Milling & Sourcing supports bulk and factory-direct sourcing programs for lag screws, serving construction suppliers, agricultural manufacturers, pole barn builders, industrial distributors, and OEM procurement teams requiring dependable volume supply and competitive pricing.
We structure recurring import programs aligned with project schedules, container consolidation, and long-term sourcing strategies.
