Stainless Steel Hex Slotted Castle Nuts DIN935
Hex Slotted Castle Nuts DIN935 are essential locking fasteners designed for high-strength assemblies requiring dependable and secure connections. They are primarily used in conjunction with a bolt or threaded rod and a cotter pin — forming a positive lock that resists vibration loosening, making them especially useful in dynamic applications. These nuts are crucial in both industrial and automotive environments for safety-critical joints.
Manufactured according to the DIN935 standard, these fasteners provide high precision in dimension, uniformity in mechanical properties, and consistent quality. Hex Slotted Castle Nuts DIN935 made of stainless steel offer exceptional corrosion resistance and long-lasting durability, ensuring optimal performance even in harsh environmental conditions.
At Flybear Fastener, we specialize in providing top-tier fastening solutions, offering a comprehensive range of DIN-standard fasteners including the Hex Slotted Castle Nuts for global clients across industries.
