The Metal Lock Nut, engineered in compliance with the DIN6927 standard, is a high-performance, all-metal hex nut with an integrated flange. This specific design establishes the Metal Lock Nut as a prevailing-torque type fastener, renowned for its reliability in preventing self-loosening under vibratory conditions. Its full-metal construction distinguishes it from non-metallic insert alternatives, making it suitable for a broader range of demanding industrial applications where consistent clamping force is critical.
The core functionality of this Metal Lock Nut is derived from its innovative three-lobed locking element. This section features three precisely formed locking teeth that create a controlled interference fit with the mating bolt’s threads. As the nut is threaded on, these teeth elastically deform, generating a consistent frictional force and prevailing torque that effectively resists rotation caused by vibration and dynamic loads. This mechanism ensures a secure and durable lock without damaging the bolt threads.
A significant advantage of the all-metal Metal Lock Nut is its superior performance in high-temperature environments. Unlike nylon-insert lock nuts, whose effectiveness can diminish or fail when exposed to temperatures beyond the polymer’s limits, this nut retains its full locking capability. This characteristic makes it indispensable in applications such as automotive engines, industrial machinery, and energy systems where elevated operational temperatures are common.
The integrated flange at the base of the Metal Lock Nut serves a critical dual purpose. It acts as a built-in washer, distributing clamping force over a larger surface area. This reduces surface pressure, helps prevent damage to the fastening material, and minimizes the risk of stress relaxation. The use of corrosion-resistant stainless steel (201, 304, and 316) ensures long-term reliability in humid or corrosive environments (food processing, marine applications, and the chemical industry).
The Metal Lock Nut is a robust and versatile fastening solution designed for reliability under challenging conditions. Its combination of a three-lobed all-metal locking mechanism, an integral load-distributing flange, and high-temperature suitability makes it a preferred component across numerous sectors. Available in a range of sizes from M3 to M12 and various surface treatments, this nut provides a dependable answer to vibration-related loosening in automotive, agricultural, and clean energy applications.
