PRODUCT PARAMETER Thin nut Thin nuts (or jam nuts) have a reduced axial height compared to standard hex nuts, saving space in compact assemblies. Made from carbon steel (zinc - plated), stainless steel (304/316), or alloy steel, they follow standards like DIN 439 and ISO 4035, with sizes ranging from M4 to M36. Applications: Aerospace & Automotive: Secure parts in tight spaces such as engine bays and aircraft interiors where height is limited. Precision Machinery: Fasten shafts, bearings, or fixtures in CNC machines, robotics, and medical devices to avoid interference. Electronics & Enclosures: Connect thin metal or plastic panels in telecom racks, consumer electronics, or battery packs, supporting miniaturization. Mold & Tooling: Lock components in injection molds or jigs where clearance is restricted. Key Points: Often used as locking nuts (paired with a thicker nut) to prevent loosening. Their slim design is suitable for vibration - prone setups or applications needing frequent adjustments. Corrosion - resistant coatings ensure durability in harsh environments.
