15 x 6″ 316 Stainless T-30 Lag Screw 25/Bkt

Description

Overview

The BIG TIMBER 15 x 6″ 316 Stainless T-30 Lag Screw (SCTX156-25) is designed for heavy-duty fastening applications requiring corrosion-resistant hardware in demanding or exterior environments. Sold in a bucket of 25.

Technical Features

• Heat Treated and Hardened Construction: The manufacturing process increases tensile strength beyond that of standard lag screws, making these fasteners suitable for structural and load-bearing connections.
• 316 Stainless Steel Material: Grade 316 stainless steel provides superior resistance to corrosion, oxidation, and chloride exposure, making these screws appropriate for coastal, marine, and exterior applications.
• Deep Cutting Threads: Engineered thread geometry allows for quicker driving with reduced torque effort, increasing installation efficiency in dense or hard substrates.
• Sharp Notched Point: The precision-ground notched tip enables exact starting placement and minimizes lateral walking during initial drive, reducing pre-drilling requirements and improving accuracy.
• Built-On Round Washer Head with Smooth Edges: The integrated washer head distributes clamping load over a wider bearing surface while smooth edges provide a clean, professional finished appearance.
• T-30 Torx Drive: The six-lobe internal drive interface reduces cam-out under high torque, maintaining drive engagement throughout the full depth of installation.

Applications

• Structural timber framing and heavy wood-to-wood connections
• Exterior decking, docks, and boardwalk construction where corrosion resistance is critical
• Marine and coastal construction environments subject to salt air or moisture exposure
• Landscape structures including pergolas, retaining walls, and fencing
• Any application requiring a fastener stronger and more durable than a standard lag screw
