Screws are indispensable for mounting and tightening applications. Therefore, they are an excellent option to consider if you are looking for something to hold objects together. However, like all fasteners, screws are available in many options. Socket screws are among the many types of screws you will find in the markets. Unlike traditional or standard screws, socket screws feature a hexagonal internal drive that's built into the screw's head. Generally, a hex key or wrench is needed to tighten or loosen screws. Typically, socket screws have a higher clamping force than conventional screws, making it a preferred choice for many people. Therefore, if you are in the market for a socket screw, here are a few tips to help you choose the right set.
Consider The Head Profile
Socket screws come with different head profiles designed for different applications. Therefore, it would be best to pay extra attention to the head profile when selecting these screws. Generally, the standard socket screw head profiles are standard, high-profile, low-profile, and ultra-low-profile. Standard head profiles are the most popular you will find. With standard socket head profiles, the thread diameter and head height are usually the same. Generally, these screws are perfect for fastening applications that require high strength or clamping force.
On the other hand, high-profile socket head screws have a head height that's slightly taller than conventional socket heads. They are ideal for hard-to-reach applications. If you have limited headspace, go for low-profile socket head screws. As the name implies, their head height is shorter than standard socket heads. And if you have very limited headspace, their ultra-low-profile counterparts would be the best alternative.
Consider The Material
Socket screws are mainly available in steel because of its strength. However, you can also find alternatives like aluminium and brass. Aluminium is ideal for lightweight applications like installing hardware on windows or doors. Despite its lightweight properties compared to steel, aluminium is equally strong, so you shouldn't worry about durability. In addition, it's corrosion-resistant.
If your application is in more challenging environments that require superior corrosion resistance, you can go for zinc and nickel-plated socket screws. And if you are after aesthetics, brass would be the best option. However, it is worth noting that zinc and nickel-plated socket screws can be quite expensive, while their brass counterparts don't perform as well when it comes to corrosion resistance.
Look At the Threading
Socket screws can be fully or partially threaded. As the name implies, fully threaded screws have the whole screw threaded up to the head. On the other hand, partially threaded screws have a portion under the head that's unthreaded. It's crucial to pay extra attention to the threading type because generally, the unthreaded sections of a screw tend to be stronger than the threaded part. Therefore, assess your application and choose fully threaded socket screws if you need more clamping or holding power.
