3/8 X 3 Hex Lag Screws (C)

Engineered for robust fastening in wood and heavy timber applications, these 3/8 x 3 hex lag screws provide exceptional pull-out resistance. Their hex head allows for high-torque installation with standard wrenches, making them a reliable choice for demanding construction and framing projects in the Los Angeles area.

  • 3/8" Diameter x 3" Length
  • Low Carbon Steel Construction
  • Meets ASTM A307 Standards
  • Hex Head for High-Torque Driving
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

These industrial-grade hex lag screws are forged from low carbon steel, providing a balance of strength and durability for demanding wood construction tasks. Manufactured to meet the requirements of ASTM A307, these fasteners feature a minimum tensile strength of 60,000 psi. The coarse, deep threads are designed to bite securely into wood, creating a strong, lasting connection without the need for a nut. The hex head design facilitates easy installation with a socket wrench or impact driver, ensuring proper torque is applied for maximum holding power.

Primarily used in residential and commercial construction, our 3/8 x 3 hex lag screws are the go-to fastener for securing heavy materials to wood framing. They are essential for projects such as attaching ledger boards for decks, assembling landscape timbers, and fastening heavy equipment to wood floors. Their robust design also makes them suitable for various MRO (Maintenance, Repair, and Operations) tasks where a strong, removable wood fastener is required. This is a core industrial-grade product in our Los Angeles warehouse stock.

Specifications

  • Material: Low Carbon Steel
  • Standards: ASTM A307
  • Strength/Tensile: 60,000 psi minimum
  • Dimensions: 3/8" Diameter x 3" Length
  • Finish: Clear Zinc-Plated (ASTM B633)
  • Certifications: Mill Test Reports (MTR) available upon request

Applications

  • Construction: Securing ledger boards, framing members, and heavy timber connections.
  • Decking & Fencing: Attaching posts, rails, and support structures in outdoor projects.
  • MRO: Anchoring heavy machinery, shelving, and equipment to wood floors or supports.
  • Landscaping: Assembling retaining walls, large planters, and other outdoor wood structures.

Target Users

These commercial hex lag screws are widely used by general contractors, framing crews, deck builders, and maintenance professionals. They are essential for any project requiring a strong, reliable connection between wood components or for attaching hardware to wood.

Finish Options

Our 3/8 x 3 Hex Lag Screws are commonly available in a clear zinc-plated finish (as indicated by '(C)' in the product name) for moderate corrosion resistance in indoor or dry environments. For enhanced durability in outdoor or corrosive conditions, hot-dip galvanized options are also available. Please specify your required finish when requesting a quote.

How to Measure

Lag screws are specified by their nominal diameter and their length. The length is measured from directly underneath the flat bearing surface of the hex head to the tip of the screw. The diameter refers to the nominal diameter of the screw's body.

Example: 3/8" (Diameter) x 3" (Length) Hex Lag Screw
