Till now, we’ve talked about different bolts and nuts. However, there is another type of fastener that holds great importance in the machinery and automobile industry.
They are called socket screw fasteners.
What are Socket Screw Fasteners?
Socket screws are preferred over other screws in industrial sectors. They have high tensile strength and torque specifications. They are inexpensive and easy to install.
Due to their design, they enhance the performance of the other fasteners.
Socket screws are of different categories, depending on the head design.
Socket Head Cap Screw
These are machine screws that have cylindrical barrel-shaped heads. It contains a hexagonal socket and internal drive. The head has a smaller diameter than the other screws.
Since it has no external clearance for the spanners, it is suitable for confined spaces. The cylindrical and hex head, along with internal wrenching features, can be turned using a hexagonal-shaped drive.
The screws are installed with a counterbore. They are also called Allen head screws. They are easier to tighten to higher torque than crossed-drive fasteners.
Socket head cap screws are used in machine parts, die fixturing, and clamping.
According to your industry, you should choose the best manufacturer of socket head cap screws.
Socket head cap screws are further of different types.
One with nylon pellets- It provides an extra locking strength.
One with a nylon patch- It has a similar function as nylon pellets.
One with full thread- The entire length of the screw is threaded.
One with drilled features- There is a hole in the thread for wire thread. It enhances the safety of the screws.
Button Head Socket Cap Screws
These are threaded fasteners with rounded heads. They are beneficial in higher torque applications and offer greater clamping force.
They provide a finished appearance. They are fully threaded and manufactured with either alloy steel or stainless steel.
The button head socket cap screws have a wider bearing surface head. This helps avoid the loosening of fasteners. Further, they have no sharp edges, thus providing added safety.
Flat Head Socket Screws
Flat head socket screws are also known as hex socket countersunk screws. They have a tapered head and a flat top.
The flat top helps the screw to sit flush on the mating surface. This socket screw is also tightened with a hex key.
The flathead socket screw is one of the strongest fasteners. It is employed in moving parts on a fastened area and close-tolerance machinery.
These screws are generally made of alloy steel and used where head screws cannot protrude. It offers maximum sidewall contact.
The close contact adds extra firmness to the setups. Thus, no slipping.
Socket Screw Materials
Steel and stainless steel are the most common materials used for producing socket screws. However, steel is an expensive option.
The alternate materials include brass, zinc plated, zinc and nickel plated, and chrome.
Zinc Screws
Rust resistance is the best feature of zinc screws. Screws with zinc and nickel plating provide a tougher coating and four times corrosion resistance than the zinc plated alone.
Brass Screws
Brass screws are stronger than copper. They are less rigid than other materials, which is an added advantage.
Brass-plated screws are less resistant to corrosion than zinc-plated ones. However, solid brass offers more corrosion than stainless steel. Thus, brass screws are the ideal choice for outdoor use.
Aluminium Screws
Aluminium socket screws are lightweight and thus beneficial in automobile industries. They make excellent corrosion-resistant fasteners.
Final Thoughts
The use of socket screws solely depends on the type of industry. Their design is their USP. Bhavya Industries offers the best socket head cap screw and the best socket head shoulder screw. We believe in quality and that is what we offer. We provide the best socket screws in Punjab.
