What is a heavy hex nut used for?
A larger version of the commonly used finish hex nut, the heavy hex nut is used for large diameter and high strength threaded fastening. Hex Nuts are ideal for use in structural applications and cell tower modifications.
What is the difference between a hex nut and a heavy hex nut?
A finished hex nut, also known as a standard hex nut, has a smaller width across the flats and corners compared to a heavy hex nut. Heavy hex nuts are thicker and heavier in weight. The proof load strength is higher than a standard hex nut. Heavy hex nuts provide increased bearing surface area over finished nuts.
What is a heavy hex jam nut?
Heavy hex jam nuts are a six-sided internally threaded fastener which is only 2/3 the thickness of a heavy hex nut. The thinner pattern is sometimes used as a second nut to ‘jam’ another nut in place preventing loosening or when a low profile is needed.
What is the difference between a hex bolt and a heavy hex bolt?
The main difference between a heavy hex bolt and a regular (or finished) hex bolt is the distance across opposite flats of the hex. Heavy hex bolts are 1/8 of an inch larger than a finished hex bolt of the same diameter. The formula for determining hex size is one-and-a-half times the diameter plus 1/8″.
How heavy is a hex nut?
Pounds (lbs) per 100 pieces
| Size | Finished Hex | Heavy Hex Jam |
|---|---|---|
| 5/8″ | 7.330 | 6.960 |
| 3/4″ | 11.900 | 11.000 |
| 7/8″ | 19.000 | 16.700 |
| 1″ | 28.300 | 23.500 |
What is a heavy hex head?
Heavy hex bolts have a larger head than a standard hex bolt. They are used for bridges, highway, buildings and other construction projects. Heavy hex bolts work well with construction materials such as wood and steel.
When would you use a hex nut?
Hex Nuts. Hex nuts are a six‑sided nut and are the most commonly shaped nut today. They are used with anchor shackles, bolts, screws, and other externally threaded components. Hex nuts, in conjunction with these other fasteners, are used to connect both metal and wood components to prevent tension and movement.
How thick is a jam nut?
Jam nut size refers to its nominal thread diameter. Typically, sizes range from 1/4″ to about 2 1/2″.
What grade is a heavy hex bolt?
Heavy Hex Bolt Specifications General heavy hex bolts include ASTM A307 specifications, which covers carbon steel bolts and studs ranging from 1/4” through 4” in diameter. This is the most common heavy hex bolt and includes Grades A, B, and C which denote tensile strength, configuration, and its intended use.
How many grams is a hex nut?
Nut Weight Chart
| Hex Nuts | ||

| Nominal Size | G | |
| 1/4 | 0.2500 | 0.505 |
| 3/8 | 0.3750 | 0.650 |
| 1/2 | 0.5000 | 0.866 |
What is a Grade 5 nut?
Grade 5 Hex Nut, Plated. SAE J995 Grade 5 hex nuts are medium strength nuts manufactured from quenched and tempered medium carbon steel. Grade 5 hex nuts are available in diameters from 1/4″ through 1 1/2″ inclusive. Dimensional specifications are governed by ASME B18.
What is the difference between bronze and brass hex nuts?
About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength. These nuts tighten to the left and won’t loosen from counterclockwise motion. Bronze nuts are stronger and more resistant to salt water than brass nuts.
What are the properties of brass nuts?
These brass nuts resist rusting from water and have closely spaced threads to prevent loosening from vibration. These nuts are resistant to salt water, electrically conductive, and nonmagnetic. These metric nuts are resistant to salt water, electrically conductive, and nonmagnetic.
What is a thin hex nut made of?
Metric Brass Thin Hex Nuts Made from brass, these metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength. Bronze Thin Hex Nuts
What is the difference between standard hex nuts and half-hex nuts?
About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength. These nuts tighten to the left and won’t loosen from counterclockwise motion.
