GB6178/GB6781 M30 Hexagon Slotted Nuts

These nuts feature a hexagon shape for easy tightening with a wrench and a slotted opening for secure engagement with a screwdriver. They are commonly used in automotive, marine, and construction fields where high strength and reliability are paramount. The stainless steel composition (SS304) guarantees resistance to rust and other forms of corrosion, making them ideal for outdoor and wet environments. Additionally, their versatile design allows for use in various applications, from securing machinery parts to assembling furniture. SS304 hex slotted nuts are truly the go-to choice for professionals seeking a dependable and versatile fastening solution. 

These GB6178/GB6781 M30 hexagon slotted nuts are engineered with precise dimensions to meet the demands of high-performance fastening applications. The "M30" designation refers to the metric thread size, which has a nominal diameter of 30 millimeters, providing a robust connection point capable of withstanding substantial mechanical stress. The nuts typically feature a pitch of 3.5 mm, conforming to standard metric coarse threading. Their overall width across flats measures approximately 46 mm, making them compatible with standard-sized wrenches for efficient installation and removal. The thickness of the nut, or its height, usually ranges from 24 to 25 mm, providing ample surface contact for secure fastening.

Constructed from Stainless 304, these slotted hex nuts are not only strong but also highly resistant to environmental wear and corrosion. The slotted top is designed to allow for locking with a cotter pin, enhancing security in vibration-prone environments. Their size and build make them particularly well-suited for use in heavy-duty machinery, structural assemblies, and critical automotive connections where both strength and precision are required. The M30 size ensures compatibility with large bolts and threaded components, extending their usefulness across a wide range of industrial and mechanical contexts.
