FAQS
Q: What is a hex nut?
A: Hex nuts are a common, internally threaded fastening solution used in conjunction with bolts or screws. As the name implies, hex nuts possess a hexagonal shape whose faces serve as a wrenching surface. They are available in a variety of metric and imperial sizes and crafted in carbon and stainless steel as well as nylon. Hex nuts are used across nearly every industry from household appliances to aerospace.
Q: What is a jam nut?
A: Jam nuts are a hexagonal nut featuring a much thinner profile as compared to a standard hex nut. They are often used in pairs to prevent unwanted loosening of a bolted assembly. Jam nuts are often used in applications where tight clearances are present.
Q: How does a lock nut work?
A: Lock nuts, sometimes called prevailing torque nuts, are designed to prevent the loosening of bolted assemblies caused by vibration. When they are tightened down onto a threaded fastener, lock nuts apply added frictional force against the threads of the mating fastener. Different varieties of lock nuts provide added friction through a multitude of methods, ranging from nylon inserts to irregular threads.
Q: What is a Bolt and Nut Grade?
A: Bolt and nut grades are established by various standards organizations and are used to indicate the material and strength of a fastener. Strength requirements are typically based on the material's hardness—stronger fasteners are made from harder materials. Grading systems often include proof load or tensile strength requirements, which verify that the material can withstand the listed forces.
Q: How do I know what grade my bolt is?
A: Most bolts have head markings that indicate their grade. For SAE bolts, radial lines on the bolt head indicate the grade. For ISO bolts, raised or stamped numbers indicate the property class.
Q: What are Hex Nuts Used For?
A: Hex nuts are primarily used to fasten parts together by threading onto a bolt, creating a strong and reliable joint. They are found in countless applications, from assembling furniture and building structures to securing machinery and automotive parts. Their ease of use and availability in various materials and sizes make them suitable for both temporary and permanent connections in diverse environments.
Q: What is the Difference Between a Heavy Hex Nut and a Hex Nut?
A: The primary difference between a heavy hex nut and a standard hex nut is the size and strength. Heavy hex nuts have larger widths and thicker walls, providing greater strength and resistance to stress. This makes them ideal for high-pressure and heavy-duty applications where a standard hex nut might fail. They are commonly used in industrial and structural applications where additional durability is required.
Q: How to Remove a Stripped Hex Nut
A: 1. Use Pliers or a Vice Grip: These tools can often grip the nut tightly enough to turn it.
2 .Cut a Slot: Use a Dremel tool to cut a slot into the nut, then use a flat-head screwdriver to turn it.
3 .Nut Splitter: A specialized tool that splits the nut without damaging the bolt.
