What is heavy hex bolt?
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.
What is a double hex bolt?
Good for high-strength fastening, these screws are made from steel comparable in strength to Grade 9 steel. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw.
Are Hex bolts strong?
Stainless steel hex bolts aren’t just strong and resistant because of their finish. The entire body of the bolt is made from stainless steel. Stainless steel is corrosion resistant so can be used in high-saline locations where other fasteners would rust too quickly.
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 the difference between Hex and heavy hex?
A heavy hex nut is thicker and heavier in weight. The part has a larger diameter across the flats. They also require larger sockets and wrenches when being installed. The load strength is far higher than the standard hex nut, meaning it can bear more weight easily.
What is the difference between a hex bolt and a hex cap screw?
What is the difference between a hex bolt and a hex cap screw? A hex cap screw has tighter tolerances on the body dimensions and features a chamfered end and a washer face under the bolt head. A hex cap screw is often called a finished hex bolt. Hex bolts have a flat end and lack the washer face under the head.
What is the difference between hex bolt and hex screw?
Hex Bolts are bolts with external threading and a hex head designed to be driven by a wrench. Hex bolts may be partially threaded or fully threaded, and are available in hex cap (partially threaded after a certain length) and hex tap (always fully threaded). Hex caps and hex taps are both considered “hex bolts”.
What is a heavy hex jam nut?
Heavy hex jam nuts are thinner than a standard heavy hex nut but have the same dimension across the flats and corners. A heavy hex jam nut can be threaded onto a bolt and run tight against the standard heavy hex nut which will lock the nut in place and prevent it from backing off.
What is the difference between a hex nut and a heavy hex nut?
When would you use a hex bolt?
Hex bolts can be used in tight spaces to secure wood, metal, plastic and other materials. Hex bolts are commonly used in buildings, bridges, docks and highway structures, but you can find hex bolts in all industries and all homes. In most cases, you’ll use a wrench or a spanner to tighten or loosen hex bolts.
What is a Grade 2 hex bolt?
The grade 2 hex bolt is a low or medium carbon steel , externally threaded bolt used in economical applications where the bolt is not subject to extreme temperatures or stress beyond the limits of the diameter. The length of a hex bolt is determined by measuring from under the head of the bolt to the base of the threads.
What size are hex head bolts?
Typically, machine bolt sizes range from 1/4″ to 1 1/4″ for square heads and 3/8″ to 1 3/4″ in diameter for hex heads, and lengths span from about 3/4″ to 18″ for square and 6 1/2″ to 24″ for hex heads. Measure length from under the head to the threaded end of the bolt. Both square and hex heads are available.
What are heavy hex bolts?
Heavy Hex Bolts are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. They feature a thicker head than standard or regular hex bolts, and offer a greater bearing surface that distributes the clamping load over a wider area.
What size is a hex screw?
Steel hex cap screws range in diameter from 1/4 inch to 1 1/2 inches (0.6 to 3.8 centimeters) and from 3/8 inch to 24 inches (1 to 61 centimeters) in length; however, the very short sizes don’t come in wide diameters, and the very long sizes don’t come in thin sizes.
