Socket Head Screw

Socket Head Screw, also known as hex socket screws or Allen keys, are some of the strongest screws available. They can withstand a tremendous amount of torque and resist cam-out better than other types of fasteners.

They are made from alloy steel and scientifically heat treated to make them stronger than traditional screws of the same size.
High Strength

Also known as Allen head cap screws, these fasteners are used in applications with limited space for wrenches. They are usually a little stronger than standard hex head bolts and offer impressive clamping strength. The head diameter is about 1.5 times the thread diameter. This allows the fastener to be installed and tightened with a socket set.

These heavy duty fasteners are available in both fully and partially threaded styles. The fully-threaded fasteners have a tapped thread all the way to the head, while the partially-threaded types have a hex drive hole that extends only part of the way to the head.

These durable fasteners are often used in machine assembly and industrial applications where panel installation requires a smooth appearance and no protrusions that could catch on machinery. They are also highly resistant to corrosion and temperature extremes.
High Tensile Strength

Designed for heavy-duty applications, socket head cap screws (also known as Allen caps, Allen head bolts or Hex head cap screws) have a high tensile strength. This allows them to hold a great amount of pressure and resist rotational and lateral movement.

These fasteners are commonly used in construction, industrial production and other projects that require a high-strength connection. They can also withstand extreme temperatures and conditions, such as those found in oil and gas fields and power generation equipment.

These screw types are available in both fully and partially threaded styles. They’re also subject to a number of standards, which ensures that they’re produced and used consistently and safely. These requirements include the material and design of the fastener, as well as its dimensional specifications.
Easy To Tighten

Unlike screw heads like Phillips, slotted and flathead screws, Socket Head Screws have an internal hex drive built into their heads, making them easy to tighten or loosen with a wrench. This makes them ideal for heavy-duty projects where greater strength is needed.

Hex socket drive bolts and screws are ideal for confined spaces that do not leave room for wrenches or sockets, and they provide better clamping pressure than other types of bolts. They are also less likely to cam-out.

If you are dealing with a stripped or rusted socket cap screw, try using a screw extractor set that is made from hardened and heat-treated alloy steel to save yourself time and effort in the long run. A hex bit and channel-lock pliers are also useful tools to have in your tool kit to remove stubborn bolts and screws.
Easy To Loosen

Socket Head Screws are one of the strongest types of screws available. They are easy to tighten using a hex-shaped wrench and can withstand a great deal of torque.

These fasteners are commonly used in industrial applications and assembly lines. There are several different types of Socket Screws to choose from including Flat Head, Low Head and Allen Drive screws.

Socket screws have a small cylindrical head with tall vertical sides and a recessed hexagonal drive hole. The head is usually knurled. This type of screw is used when a greater bearing surface is required or when a more finished appearance is desired. They are also preferred when wrench clearance is limited. They can withstand a higher preload than other screw types but not as much as a bolt.
Easy To Install

Easily tightened or loosened with tools like an Allen wrench, socket head screws don’t require external torque to install. Instead, the built-in hex drive hole makes these fasteners a good choice for environments with limited access and tight spaces.

This is why you’ll find them in construction projects, furniture manufacturing and automotive applications. They can withstand high clamping forces and provide a secure connection.

These fasteners also work well for machine assembly and other applications that need a low-profile and flush installation. Some designs also feature a nylon pellet bonded on the threads that adds extra locking strength and resists loosening from vibration. This feature helps ensure your project stays strong and stable over time.
