At nearly 32 inches in length with a fully threaded shank, this long timber screw delivers exceptional withdrawal resistance in wood-to-wood connections, beam reinforcement, and cross-laminated timber applications. The black e-coat electrocoating finish provides a construction-durable, nonmetallic coating suited for interior dry-service environments while keeping the installation looking clean whether the head is left exposed or countersunk. This package includes 50 screws plus a T50 6-lobe driver bit, making it a complete solution for professional timber framing crews and structural carpentry projects.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompact cylinder head design -
