15 x 5″ 316 Stainless T-30 Lag Screw 25/Bkt

Description

Overview

The BIG TIMBER 15 x 5″ 316 Stainless T-30 Lag Screw (SCTX155-25) is designed for heavy-duty fastening applications in Home & Garden construction, outdoor structures, and environments where corrosion resistance is required.

Technical Features

• Heat-treated and hardened construction: Increases tensile strength and durability beyond standard lag screws, reducing the risk of fastener failure under load.
• 316 Stainless Steel material: Provides superior resistance to corrosion, rust, and chemical exposure, making these screws suitable for outdoor, marine, and high-moisture environments.
• Deep-cutting threads: Engineered for faster thread engagement into wood, reducing drive time and operator effort.
• Sharp notched point: Enables precise, self-starting insertion with minimal lateral movement, eliminating the need for a pilot hole in many applications and reducing material walking.
• T-30 Torx drive: Delivers improved torque transfer and reduced cam-out compared to standard hex or Phillips drives, supporting consistent, high-torque installation.
• Built-on round washer head with smooth edges: Distributes clamping load over a larger surface area while providing a clean, professional finish at the fastener seat.
• 25-count bucket packaging: Keeps fasteners organized and accessible on the job site, reducing handling time during high-volume installations.

Applications

• Deck construction and ledger board attachment where corrosion resistance is critical
• Outdoor structural framing, pergolas, and timber framing
• Dock and marina construction utilizing 316 stainless steel for saltwater environments
• Fence post and retaining wall fastening requiring long-term weather resistance
• Heavy timber joinery in landscape and garden structures
