Professional Hex nut Solutions

Nuts and custom solutions for industrial applications

JF produces a wide range of heavy hex nuts designed for high-stress applications in industries such as oil&gas and petrochemical, marine, nuclear, rail, renewable and power generation. Our products, such as A194 7M heavy hex nuts and A194 8M heavy hex nuts, offer superior strength and reliability, particularly in demanding environments for structural applications.

These nuts are frequently used in conjunction with heavy-duty stud bolts to secure critical components, such as flanges, valves and pressure vessels. In recent years JF has focused on the constant increase in demand of exotic materials and is now the market leader in the supply of bolting in nickel-alloys, stainless and super-duplex such as nuts 625, nuts 660a and nuts 718.
