BS EN 3721:1995 Nuts - The Ultimate Solution for High-Temperature Applications

Introducing the BS EN 3721:1995 Nuts, a premium standard in the world of fasteners, designed to meet the rigorous demands of high-temperature environments. These nuts are not just any ordinary fasteners; they are engineered to provide exceptional performance and reliability in the most challenging conditions.

Product Overview

The BS EN 3721:1995 standard specifies the requirements for bihexagonal, self-locking, deep counterbored nuts made from heat-resisting steel, specifically the FE-PA92HT (A 286) alloy. These nuts are further enhanced with a MoS₂ coating, ensuring superior performance in high-stress applications.

Key Features

• Bihexagonal Design: The unique bihexagonal shape provides enhanced grip and torque distribution, ensuring a secure fit even under extreme conditions.
• Self-Locking Mechanism: The self-locking feature prevents loosening due to vibration or thermal expansion, making these nuts ideal for dynamic applications.
• Deep Counterbored: The deep counterbored design allows for a flush fit, reducing the risk of snagging and improving the overall aesthetics of the assembly.
• Heat Resisting Steel: Made from FE-PA92HT (A 286), these nuts are capable of withstanding high temperatures, maintaining their integrity and performance up to 425°C.
• MoS₂ Coating: The molybdenum disulfide coating provides excellent lubrication, reducing friction and wear, and extending the lifespan of the nuts.
