Description
The 304 Stainless Steel Hex Slotted Nut is a high-quality locking fastener with a hexagonal shape and slotted top that allows for secure fastening through the use of a pin or cotter. This Hex Slotted Nut is made of 304 stainless steel, offering excellent corrosion resistance, and adheres to Chinese standards for dimensional accuracy and performance. Engineered to GB6178/GB6181 standards, these hexagonal nuts provide outstanding wear resistance, corrosion resistance, and long-lasting performance, even in harsh environments. Whether you’re working in automotive repair, industrial assembly, or heavy-duty construction, A2-70 stainless steel hex slotted nuts deliver reliable performance you can trust.
Features & Benefits
- Positive Locking Mechanism: The defining feature of a slotted nut is the slots on its top face. A cotter pin or wire is passed through these slots and a hole in the bolt's shank, effectively preventing the nut from rotating or backing off.
- Corrosion-Resistant Material: Made from 304 stainless steel (A2-70), offering superior corrosion resistance, oxidation resistance, and long-term reliability.
- High Strength and Hardness: The 304 stainless steel provides exceptional hardness and strength, resisting deformation under load and preventing the nut from stripping.
- Standardized Design: Manufactured to GB6178/GB6181 standards, this hexagonal nut has a standard shape and deep threads, ensuring a uniform force distribution and preventing slippage during installation.
