China Hexagon Slotted Nut Manufacturer, Supplier, Factory
Hexagon slotted nuts are specialized fasteners designed for high-vibration applications, providing a secure mechanical lock when used with cotter pins. These nuts feature a hexagon shape for easy installation with standard wrenches and have slots cut into the top to accommodate a cotter pin, which prevents the nut from loosening under dynamic loads. This makes them essential in industries such as automotive, aerospace, and heavy machinery. If you require other fastener types, we also offer a range of products including Hexagon Nut, Square Nut, Hexagon Flange Nut, and Lock Nut, each designed to meet specific fastening needs with precision and durability.
The Hexagon Slotted Nut is engineered from high-grade materials to ensure longevity and performance. Common materials include carbon steel, stainless steel, and brass, each selected based on the application's corrosion resistance and strength requirements. Key parameters of the Hexagon Slotted Nut include precise thread sizes, slot dimensions, and hexagon widths, which are critical for compatibility and safety. Below is a detailed breakdown of the product specifications:
- Material Options: Carbon Steel, Stainless Steel, Brass
- Standards: DIN 935, ISO 7719, ANSI B18.2.2
- Thread Types: Metric (e.g., M6 to M24) and Imperial (e.g., 1/4" to 1")
- Slot Width: Designed to fit standard cotter pins (e.g., 1.5mm to 3mm)
- Surface Treatments: Zinc plating, hot-dip galvanizing, or natural finish for enhanced durability
| Size (Metric) | Across Flats (mm) | Thread Pitch (mm) | Slot Width (mm) | Material Grade |
|---|---|---|---|---|
| M6 | 10 | 1.0 | 1.5 | Grade 5/8.8 |
| M8 | 13 | 1.25 | 2.0 | Grade 5/8.8 |
| M10 | 17 | 1.5 | 2.5 | Grade 8/10.9 |
| M12 | 19 | 1.75 | 3.0 | Grade 8/10.9 |
| M16 | 24 | 2.0 | 3.0 | Grade 8/10.9 |
| M20 | 30 | 2.5 | 3.0 | Grade 8/10.9 |
For imperial sizes, common specifications include 1/4" with a 7/16" across flats and 1.5mm slot, up to 1" with 1-1/2" across flats and 3mm slot. The Hexagon Slotted Nut undergoes rigorous quality checks to meet industry standards, ensuring reliable performance in critical assemblies. Proper installation involves threading the nut onto a bolt, aligning the slot with a hole in the bolt, and inserting a cotter pin to lock it in place. This design is ideal for applications where safety and vibration resistance are paramount, such as in wheel hubs, steering systems, and industrial equipment.
