Introducing the FastenMaster FMTLOK10-50A TimberLOK 10" fasteners—a 50-piece box built for speed, strength, and reliability on every project. Designed to power through wood with precision, these TimberLOK fasteners cut installation time dramatically while delivering superior holding power for long-lasting results.

TimberLOK’s sharp point and aggressive threads are engineered to penetrate even the densest woods without predrilling, so you can move from one joint to the next without interruption. The unique countersinking head sits flush for a clean, professional finish, making the TimberLOK ideal for visible decks and fencing as well as hidden connections. When you’re framing a deck, attaching a fence, or securing a post to a beam, these fasteners stay true to size and depth, reducing wood splitting and ensuring reliable shear strength.

• No predrilling required—save time and labor on every deck, fence, or framing job.
• Stronger shear values than 3/8" galvanized lag screws in many wood-to-wood applications.
• Countersinking head design for flush, smooth connections and a polished look.
• Versatile for deck framing, fencing, post-to-beam connections, raised beds, landscaping, and retaining walls.
• Includes a free 5/6 inch driver bit with every box—shop-ready out of the bag.
• American-made quality you can rely on for consistent performance and local support.
• 10" length provides robust bite for thick members while maintaining a clean finish.
• 50-piece box keeps your on-site supply ample for larger jobs or multiple projects.

The TimberLOK is an ideal choice for homeowners and professionals who want quicker installations without sacrificing hold and durability. Replace galvanized spikes in raised flower beds or landscaper-grade structures, secure heavy-duty fence lines, or build solid deck connections with confidence. This is a practical upgrade for anyone looking to streamline wood-to-wood connections and achieve a sturdy, lasting result with fewer tool changes and less downtime.

Whether you’re a contractor tackling a multi-day deck build, a gardener installing durable raised beds, or a DIYer upgrading an old fence, the TimberLOK 10" fasteners deliver reliable performance, job-site efficiency, and American-made assurance you can trust.
