15 x 6″ Black T-30 Wafer Head Lag Screw 25/Bucket

Description

Overview

The Big Timber 15 x 6″ Black T-30 Wafer Head Lag Screw (WTX156-25) is designed for heavy-duty structural fastening applications requiring compatibility with treated lumber.

Technical Features

• T-30 Torx Drive: The star-pattern drive recess provides increased bit engagement and reduced cam-out compared to standard hex or Phillips drives, improving installation control under high torque.
• Wafer Head Profile: The low-profile wafer head distributes clamping load over a broader surface area, reducing the risk of material pull-through in structural connections.
• 6″ Fastener Length: Extended length provides deep thread penetration into substrate material, supporting high withdrawal resistance in timber-to-timber and ledger-board applications.
• Black Finish: Provides a uniform, low-visibility appearance suited to applications where exposed fastener aesthetics matter.
• Treated Lumber Compatibility: Engineered for use with pressure-treated lumber, a common requirement in deck, framing, and outdoor structural builds.
• 25-Count Bucket Packaging: Bucket format protects fasteners during job-site transport and storage while keeping quantities manageable for focused structural tasks.

Applications

• Structural framing and ledger connections using pressure-treated lumber
• Deck construction and outdoor structural assemblies
• General heavy-duty lag fastening where a T-30 drive tool is available
