Round Head Nip Bolts Crane Mat Rod Hot-Dip Galvanized Timber Bolt

This bolt is designed for timber fastening, doubling as a crane mat rod to secure timber crane mats for stable construction crane support. Made from high-strength carbon steel, it delivers reliable tensile strength (≥600MPa) to hold timber joints tight and resist loosening from vibration or load shifts. Its hot-dip galvanized finish offers heavy-duty corrosion resistance, making it ideal for outdoor or industrial timber projects like docks or sheds. The round head provides a smooth, low-profile look on wood surfaces while preventing snagging, and its coarse thread ensures a strong grip in timber—suitable for both wood-to-wood and wood-to-metal connections.

Parameter Category	Specification Details
Material	carbon steel
Surface Treatment	Hot-dip galvanization (HDG)
Typical Thread Size	Metric: M10–M24; Imperial: 3/8"–1" (suitable for standard timber and crane mat thicknesses)
Shaft Length	80mm–300mm (varies by timber thickness; customizable for deep timber joints)
Tensile Strength	≥600MPa (meets timber fastening and crane mat load requirements)

Applications:

Fastening timber crane mats for construction crane support
Securing wooden structures (e.g., outdoor docks, storage sheds)
Creating wood-to-metal connections in outdoor infrastructure
Reinforcing timber joints in industrial wooden equipment
Assembling heavy-duty timber platforms for construction sites

Q & A

Q: Why is this bolt called a "nip bolt" and what does that feature do? A: It’s called a "nip bolt" because it’s designed to "nip" (tighten) timber joints firmly. This prevents the joints from loosening due to vibration (e.g., crane operation) or load shifts, keeping timber structures stable.
Q: What makes it suitable to be a "crane mat rod"? A: Its high-strength carbon steel (tensile strength ≥600MPa) and coarse thread let it fasten heavy timber crane mats securely. This creates a stable base for construction cranes, supporting the crane’s weight without bending or breaking.
Q: How does "hot-dip galvanization" benefit its use in timber projects? A: Hot-dip galvanization forms a thick, durable protective layer against rust. This is critical for timber projects (like outdoor docks or crane mats) that are exposed to moisture, ensuring the bolt doesn’t corrode and maintains its fastening strength long-term.
Q: Why choose a "round head" design for timber fastening? A: The round head has a smooth, low-profile shape. It avoids snagging on equipment or materials (common in construction sites) and leaves a neat finish on visible timber surfaces, unlike sharp or protruding head designs.
Q: Can this bolt be used for both wood-to-wood and wood-to-metal connections? A: Yes—its coarse thread grips tightly in timber for wood-to-wood joints, and its high strength also allows it to fasten timber to metal components (e.g., wooden docks to metal frames) in outdoor infrastructure.
