High-Quality Hex Head Lag Screws

What is a Hex Head Lag Screw?

A hex head lag screw (also widely referred to in the construction industry as a lag bolt) is a heavy-duty, full-bodied threaded fastener engineered specifically for high-strength framing and lumber applications. Designed with a sturdy six-sided hex head, deeply spaced threads, and a sharp gimlet point, these incredibly durable fasteners are the industry standard for securely connecting thick lumber and heavy, load-bearing materials.

Design Features and Structural Applications

Because of their tough exterior and exceptional structural strength, hex head lag screws provide maximum holding power and offer several key mechanical advantages for wood construction:

• Gimlet Point and Spaced Threads: The ultra-sharp gimlet point allows the fastener to bite immediately into the mating surface, while the deep, widely spaced threads aggressively grip the wood to prevent the fastener from pulling out under extreme structural loads.
• Hexagonal Head Design: The thick hex head provides a highly secure grip for wrenches and socket tools, allowing installers to apply maximum torque without the risk of the drive camming out or stripping during heavy-duty installations.
• Heavy Timber Construction: Due to their massive sheer strength, they are primarily utilized in heavy wood construction, including deck framing, retaining walls, timber trusses, and securely anchoring heavy machinery to wooden flooring.

Available Materials and Dimensions

To guarantee maximum holding power and long-term environmental durability, U-Bolt-It manufactures hex head lag screws in a comprehensive variety of dimensions, thread lengths, and industrial-grade materials.
