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.

Why Choose?

• Precision Engineering: Manufactured with strict quality control to meet international standards.
• High Load-Bearing Capacity: Designed to withstand heavy loads in industrial applications.
• Corrosion-Resistant Coatings: HDG and GI finishes extend the lifespan of the bolts in outdoor and marine environments.
• Custom Manufacturing: Available in different sizes and finishes based on project requirements.
• Easy Installation: Designed for quick and hassle-free assembly with minimal tools.
