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.

Why are hex heads used?

Hex head screws that tap their own hole are also known as lag or coach screws. They’re used to join heavy timber or heavy objects with timber. They can also attach heavy objects to masonry or light objects to steel.

What is the difference between hex head cap screw and a socket screw?

Socket head cap screws are not grade designated as are hex head cap screws. A standard inch series socket head cap screw is 20\% stronger than a Grade 8 hex head cap screw and 50\% stronger than a Grade 5 hex cap screw. The tensile strength is a minimum 180,000 psi for sizes 1�?

Why might you use a cap or socket headed machine screw over a hexagonal headed machine screw?

Technical equipment and electronics often use socket head cap screws, creating a visual association that may carry over to other products and applications. Others claim that socket head cap screws round out easily, while it takes extreme pressure with repeated use to round off hex head styles.

What is a hex nut used for?

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.

When did they start using hex head bolts?

NUTS & BOLTS The hex head was developed as far back as the very early 1830’s (James Nasmith) , and the square continued mainly in the production of agricultural implements.

What is a hex head bolt?

Hex bolts, or hex cap screws, are large bolts with a six-sided head (hexagonal!) used to fasten wood to wood, or metal to wood. Hex bolts have small threads and a smooth shank, and may be plain steel for interior projects or stainless steel or galvanized for exterior use.

What is hex socket head bolt?

Hexagon socket head cap screws (cap bolts) Bolts with a hexagonal hole on a cylindrical head that’s fastened with a hex wrench.

Is a hex same as a socket?

A “hex” socket—short for “hexagonal”—is a socket that fits around a hexagonal (six sided) nut or bolt head. There are two types of hex sockets – six point and twelve point. The twelve-point socket—also sometimes called a “double hex” or “bi-hex”—has twelve angles in the bolt end.

What is the difference between a hex nut and a lock nut?

Hexagon Nuts A hexagon nut is a standard fastener and one of the most basic fastening solutions. It’s not technically a locking nut, but by using two nuts together (typically one standard hexagon nut and a thin hexagon nut) they act as a type of locknut, but have limited resistance to loosening under vibration.

What is the difference between a hex nut and a jam nut?

The main differences between a jam nut and a regular hex nut is that they are tightened against each other instead of against a material, and that they are about half of the size of a regular nut.

Should you use socket head or hex head cap screws?

Some professionals choose to use the socket head style due to quality issues or repeated stripping with hex head cap screws. Others claim that socket head cap screws round out easily, while it takes extreme pressure with repeated use to round off hex head styles.

What is the difference between hex bolts and hex heads?

Hex Bolts 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”.

Are Socket screws stronger than hex screws?

Socket head screws are usually a better alloy than hex heads. You have to take this with a grain of salt in that, I believe, all inch SHCS are stronger than grade 8, while some metric SHCS are.

What is the difference between a tap bolt and hex cap screw?

Both are typically installed with a nut and designed to be driven by a wrench or socket driver. And last but not least, if a hex cap screw is small enough to lose its shoulder it can also be considered a tap bolt. In smaller sizes, they are the same but once a unthreaded shoulder starts, become different bolts.
