Advantages of Socket Cap Screws
Benefits of Socket Cap Screws
The screw keeps the modern world together. Socket cap screws are the latest improvement on an invention that's been around since 400 BC. An inventor first created the screw thread in ancient Greece to raise water and olive oil from casks and containers. It was later used to irrigate fields and rid leaky ships of water in their bilges.
It wasn’t until 1568 that the screw concept was perfected and used to bind two surfaces together. A French inventor named Jacques Besson invented a nut and bolt manufacturing machine. With the surge in availability, the use of nuts, bolts, and screws as fasteners began to gain widespread popularity.
Today, it may seem like the modern world is held together by these small but crucial fasteners. There are many adaptations of the screw used, depending on the fastener’s intended applications.
Evolution of the Common Screw
The type of screw that most people are familiar with is the slotted screw. These were quickly, easily, and cheaply produced in mass quantities during the industrial revolution when they became popular, so they’re commonly seen in every type of application, from household appliances and automobiles to building construction.
Slotted screwdrivers used to install and remove the screws are also relatively cheap tools to make. Almost every household has one.
However, this type of screw is not the best at its primary job. As the world's engineers became more knowledgeable about fasteners, they began to experiment to improve the amount of torque that could be applied to the screw. Washers were also often included in the application of screws as they provided more grip on smooth surfaces.
The engineers and inventors knew that the more surface area where the driving tool fit into the end of the screw, the more torque it could handle. The screwdriver was also less likely to slip with this more solid connection.
The next most popular evolution in the design of screw heads was the Phillips head screw. These are easily identified by the cross-shape indentation in the head that corresponds to the pointed cross-shape at the end of the screwdriver.
The concept was designed to lessen the tendency of the screwdriver to slip laterally out of the slot by making two perpendicular slots, thereby increasing the stability of the screwdriver. It performed as promised. The Phillips head screw was also able to be tightened with more torque because of the added surface area of the perpendicular slots.
The Next Step
Allen screws were the next step in creating a fastener that could handle increased torque. This concept was the first use of the hexagonal shape to secure fasteners and was the precursor to the socket cap screw.
Allen screws were installed with corresponding Allen wrenches. They were hexagonal-shaped steel bars that were bent at a 90-degree angle to provide a handle the installer could use to screw in the fastener.
The improvement in torque came from the fact that Allen keys could be made deeper than slotted or Phillips head screws and thus allowed much greater surface area on the inside face of the screws. The hexagonal shape also effectively eliminated any slipping of the Allen wrench.
The hexagonal shape was adopted into socket cap screws that could be manufactured to almost any depth required. These screws transmitted a tremendous amount of torque for their size. The fact that their drivers could use the same 90-degree bend as Allen wrenches meant the screws were ideal for applications in tight quarters. These screws could easily be placed in machines with a limited amount of room over the top of the screw and still be tightened easily. Socket cap screws should not be confused with hex head bolts that use the hexagon-shape on the outside to tighten the bolt with a crescent or slotted wrench.
