Fin Neck Bolt / Round Head Bolt
Fin Neck Bolt Overview:
We manufacture Fin Neck Bolt in various grades, including 8.8, A307, and 4.8, with high-quality finishes such as Hot Dip Galvanized (HDG), Yellow Zinc Plated, and Galvanized Iron (GI). These bolts are commonly used in steel railings, timber/wood applications, and other structural installations.
Key Features
- Self-Locking Mechanism: The fin neck design locks into steel or wood surfaces, enabling single-person bolt tightening.
- Multiple Head Options: Available in Pan Head or Round Head configurations for versatile applications.
- Full-Length Threading: Threaded entirely to the base of the fins, ensuring a strong and secure connection.
- Durability & Strength: Made from high-quality low-carbon steel, providing excellent mechanical strength and resistance to wear.
- Corrosion Resistance: Various coatings available, including HDG and GI, to prevent rusting in harsh environments.
General Applications Primarily Used.
- Timber and Woodworking: Ensuring a secure fit in plywood and wooden structures.
- Steel Railing Installations: Providing structural integrity and stability.
- Metal Fabrication: Ideal for joining metal plates with wood or other materials.
- Construction & Infrastructure: Used in frameworks, securing beams, and industrial applications.
- Furniture Assembly: Common in assembling wooden furniture for a sturdy connection.
Technical Specifications
- Standard: ASME B18.
- Common Sizes: 1/2”x3/4”, M12x25, and M12x35 (other custom sizes available upon request).
- Head Type: Shallow Mushroom Head (Dome Head) with a smooth finish.
- Shank: Circular shank with a square section immediately below the head, allowing secure locking.
- Bearing Surface: Flat surface at a 90° angle with the shank for stable fastening.
How Fin Neck Bolts Work
Unlike traditional bolts, Fin Neck Bolts feature a square section beneath the head, which locks into a pre-drilled square hole in a steel strap or wood surface. This prevents the bolt from spinning during tightening, allowing for easy one-tool installation with a spanner or wrench from one side. This feature makes Fin Neck Bolts particularly efficient in applications where only one worker is available for tightening.
