These 201 stainless steel locking nuts are designed to resist loosening in vibratory or dynamic applications. Each nut features a nylon insert that creates a selflocking action, providing reliable antislip performance without the need for additional locking devices. Key benefits Prevents loosening under vibration: nylon insert increases friction between nut and bolt, reducing backoff and maintenance. Durable, corrosionresistant material: made from 201 stainless steel for reliable performance in indoor and outdoor environments. Easy to install and remove: standard hex nut shape fits common wrenches, enabling straightforward installation and removal when needed. Wide size range for versatility: available in multiple metric sizes to cover many common fastening needs, from M18 to M33 (including M24). Consistent locking performance: the nylon insert maintains its grip over time, helping keep assemblies secure even under dynamic loads. Key attributes Functionality: selflocking hex nuts with nylon inserts for antiloosening, antislip performance. Material: 201 stainless steel for corrosion resistance and durability. Finish: hexagonal geometry designed for reliable wrench engagement. Size range: M18, M20, M24, M27, M30, M33. Compatibility: metric threads compatible with corresponding bolt sizes; suitable for various standard assemblies. Performance: designed to resist loosening from vibration and cycling without requiring additional locking hardware. Specifications overview Material: 201 stainless steel Locking mechanism: nylon insert (antiloosening, antislip) Shape: hex nut Available sizes: M18, M20, M24, M27, M30, M33 (M24 included in the set) Applications: general mechanical assemblies where vibration may cause fastener loosening Applications and use cases Industrial machinery and equipment: secure mounting of components on vibrating machines, conveyors, and gear assemblies to reduce maintenance intervals. Automotive and motors: hold brackets, housings, and components subjected to engine vibration or dynamic loads. Outdoor equipment and construction: fastenings that endure exposure to weather and movement, such as power tools, garden machinery, and outdoor structural components. Installation and care notes Install with standard wrenches designed for hex nuts; select the size that matches the bolt used. Ensure mating bolts are clean and threads are in good condition for locking performance. Inspect nylon insert periodically; nuts if the insert shows wear or deformation. Store in a dry environment to preserve nylon integrity and prevent corrosion. This product line delivers a reliable locking solution with a durable stainless steel body and a nylon insert that helps prevent loosening in a range of M18 to M33 sized applications.
