This product is a line of stainless steel antitooth hex nuts with lefthand thread, available in sizes M3 through M24, plus a separate M22 option in a 5piece pack. Offered in 5, 10, 50, or 100 pieces per lot, these nuts are designed for applications that require reversethread fasteners in durable, corrosionresistant hardware. Key benefits Lefthand thread for reverserotation applications: uses a lefthanded (reverse) thread to prevent loosening in systems exposed to loads or motions that tend to rotate in the opposite direction. Corrosionresistant stainless steel: suitable for challenging environments, including moisture and outdoor use, to extend fastener life. Antitooth design: engineered to improve grip and resist wear in demanding, torque or vibration settings. Standard hex geometry: compatible with common tools and provides reliable torque transmission. Wide size range for versatile use: supports bolts from M3 up to M24, with an additional M22 5piece option, enabling broad applicability across projects. Flexible quantity options: choose from 5, 10, 50, or 100 pieces per lot to fit budgeting and project scale. Key attributes Functionality: lefthand threaded hex nuts for secure fastening in reversethread assemblies. Compatibility: designed to work with corresponding lefthand threaded bolts in the M3–M24 range; M22 option available in a 5piece pack. Size range: M3, M4, M5, M6, M8, M10, M12, M14, M16, M20, M22, M24 (M3–M24 span); specific M22 variant offered as 5PCS. Material: stainless steel for corrosion resistance and durability. Performance: robust hex nut design with antitooth features intended to minimize wear and maintain clamping force in dynamic environments. What's included Available in bundles of 5, 10, 50, or 100 pieces per lot. M3–M24 sizes available; M22 size included as a separate 5piece option. Applications and use cases Counterrotating or vibrationprone machinery: lefthand threaded nuts help prevent loosening where rotation direction or vibration would otherwise loosen standard righthand fasteners. Marine, outdoor, or humid environments: stainless steel provides better resistance to corrosion, extending component life in challenging conditions. Gearboxes, winches, conveyors, and other equipment with lefthanded threaded components: ensures reliable fastening in assemblies that use reversethreaded hardware. DIY and projects requiring a mix of sizes and a lefthanded fastener option: the variety of pack sizes and the M3–M24 range support flexible sourcing for hobbyists and professionals. Notes Lefthand thread indicates a reverse rotation direction compared with standard righthand threaded fasteners. This description reflects the product's brand alignment, specifications, model, and features as listed in the title: stainless steel antitooth hex nuts with lefthand thread, covering M3–M24 sizes (and M22 5PCS), available in 5/10/50/100 piece lots.
