Fishtail bolts, also known as fish bolts, are a type of fastener designed with a specialized shape that includes a downward-facing end and no threads on the underside. This unique design ensures they can hold up under demanding conditions and reduces the chances of loosening.

Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.

Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.

Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.

Advantage:

Specialized Design: The downward-facing end and the lack of threads on the underside allow fishtail bolts to fit into tight spaces and provide a secure grip in applications where traditional bolts may not be suitable.Secure Fit: The fishtail shape helps maintain a tight grip even under extreme pressure or vibration.Versatility: They are used in various industries, including automotive manufacturing, medical equipment assembly, and aerospace engineering.Easy Installation: No additional tools or special hardware are required for installation—only a wrench or ratchet is needed.

Scope of 

application

Automotive Industry: Used in applications with limited space and high levels of vibration or stress.Machinery and Equipment: Secure components in industrial machinery that must remain stationary during operation.Construction: Employed in building structures where a secure connection is required.Aerospace Engineering: Utilized in applications where a compact and secure fastening solution is needed.
