Overview
Self-drilling screws are fasteners designed with an integrated drill point that eliminates the need for pre-drilling. Engineered for fastening metal to metal or metal to wood, these screws reduce installation time while providing secure, high-strength connections.
Often referred to as TEK screws, self-drilling screws are widely used in construction, steel fabrication, HVAC systems, roofing, and industrial manufacturing.
Offshore Milling & Sourcing supports bulk and factory-direct sourcing programs for self-drilling screws, serving contractors, steel building suppliers, OEM manufacturers, and industrial distributors requiring dependable high-volume supply and competitive pricing.
We structure recurring import programs aligned with project schedules, container consolidation, and long-term sourcing strategies.
