Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

This hex head lag screw is manufactured from durable low carbon steel, providing the necessary strength for general-purpose fastening applications. It is designed to meet the performance requirements of ASTM A307, ensuring a minimum tensile strength of 60,000 psi for dependable connections. The screw features a coarse thread pitch for excellent grip in wood and a gimlet point for easy starting. A zinc coating applied per ASTM B633 standards provides a protective barrier against moisture and corrosion, extending the fastener's service life in various environments.

Ideal for light-duty framing, deck construction, and general repair, these lag screws are a staple for contractors and fabricators in Los Angeles. They are used to fasten wood members together, attach hardware to wood, or secure structural elements in residential and commercial projects. The hex head design facilitates high torque application for a secure, tight fit. Available for same-day pickup from our Los Angeles warehouse, these industrial-grade lag screws are a reliable choice for both new construction and maintenance, repair, and operations (MRO) tasks.

Specifications

  • Material: Low Carbon Steel
  • Standards: ASTM A307, ASTM B633 (Plating)
  • Strength/Tensile: 60,000 psi (Minimum)
  • Dimensions: 1/2" Diameter x 4" Length
  • Finish: Zinc Plated
  • Certifications: Mill Test Reports (MTR) available upon request.

Applications

  • Construction: Securing deck ledgers, framing members, outdoor structures, and landscape timbers.
  • Fabrication: Attaching metal brackets, flanges, or hardware to wooden posts or beams.
  • MRO & Repair: General repairs on wooden structures, machinery crating, and industrial shelving.
  • Architectural: Fastening ornamental ironwork or fixtures to wood substrates in commercial projects.

Target Users

This product is essential for general contractors, framing crews, deck builders, and maintenance professionals in the Los Angeles area requiring a strong, corrosion-resistant fastener for wood applications.

Finish Options

This hex lag screw comes with a standard zinc-plated finish (ASTM B633) for good corrosion resistance. For applications requiring superior weather protection, hot-dip galvanized and stainless steel options are also available by special order.

How to Measure

Lag screws are specified by their nominal diameter (the shank diameter) and their length, which is measured from directly under the head to the tip of the screw.

Example: A 1/2" x 4" Hex Lag Screw has a 1/2-inch shank diameter and is 4 inches long from the bearing surface of the head to the point.
