Lag Screw
- UM: M
The Lag Screw is a high-strength threaded fastener engineered for secure anchoring into wood or lag anchors in structural applications. Designed to handle heavy loads, lag screws are commonly used where strong, vibration-resistant connections are required in both indoor and outdoor environments.
Tengco supplies lag screws in custom sizes, materials, and finishes to match specific structural and environmental requirements. Whether used in construction framing, equipment mounting, or infrastructure projects, these fasteners are built for dependable long-term performance.
Lag screws are typically manufactured through cold forming or hot forging processes using carbon or alloy steel. After forming, they are heat-treated to achieve the strength and hardness needed for demanding structural applications. Protective finishes such as zinc plating or hot-dip galvanizing are applied to improve corrosion resistance in exposed installations.
