K Lock Nuts

K Lock nuts are distinguished by their integrated free-spinning external tooth lock washer, which provides increased grip and resistance to vibration. Ideal for use with a variety of fasteners (including low-carbon steel machine screws), they are versatile and easy to install – simply tighten the nut in place like normal with a standard wrench until the teeth lock against the mating surface. However, it is important not to over-tighten them, as this will cause the teeth to flatten and lose their locking capabilities. Huyett offers these locking fasteners in steel with zinc finishes to withstand the rigors of demanding and corrosive environments. Their unique construction makes them suitable for high-vibration applications where standard hex nuts may fail to maintain a secure hold.

The external tooth lock washer bites into the mating surface to provide resistance to vibration and loosening under movement or torque. This feature is particularly beneficial in industries like automotive and aerospace, where safety and reliability are paramount. Additionally, K Lock nuts offer increased torque capabilities, reducing maintenance costs and downtime associated with frequent re-tightening, replacement, or installation with multiple locking fasteners. Their ease of installation and removal adds to their appeal and makes them a practical choice for a wide range of mechanical systems.

K Lock nuts feature an integrated external tooth lock washer that bites into the mating component for extra holding power. Traditional hex nuts are well suited for general-purpose applications that do not require additional security.

This depends on how they were initially used. If they were used with a material that damaged the teeth, or if the nut was over-torqued and the teeth bent out of place, the locking power will significantly decrease. Carefully inspect the fastener to see if the teeth are in good enough condition to facilitate the appropriate locking mechanism.
