Socket screws, also called Allen head screws or bolts, are screw types that feature hexagonal head drives designed to lose or tighten various materials using hex keys or Allen wrenches. These screws resist tightening using traditional screwdrivers and are ideal for hard-to-access areas where they are difficult to operate using standard sockets or wrenches.
Furthermore, these screws are distinguished due to their unique head drive from other screw types, including Phillips head screws, Pozidrive screws, and flathead screws. The Allen head screws offer robust performance, easy installation, and lower weight over the finished surface. Additionally, they come in distinct metric sizes and types and are made from durable materials.
Key Benefits of Socket Screws
Socket screws offer numerous benefits over common screws due to their higher clamping and torque force. Other benefits include:
- They are cost-effective with overall lightweight for finished pieces.
- They are timesaving with easy to install.
- Made from high-quality and durable materials.
- Reduced component damage.
- Take less space requiring fewer holes for drilling and tapping into surfaces.
- Available in several types with different head shapes and styles.
Socket Screw Materials and Sizes
Socket screws are made from varied materials, and the most common materials include steel, stainless steel, brass, chromium, black nickel, aluminium, and zinc-plated screws.
Moreover, they also come in different screw sizes that are ideal for specific tasks and applications. They are available in larger, extra-long, and heavier gauge screws with M8 to M20 ranges of width and up to 130 mm in length. In addition, electrical plug sockets often utilize extra-long socket screws and include sizes ranging from 40 mm to 100 mm.
Socket Screw Types/Designs
Socket screws come in distinct types, such as:
- Countersunk
- Low-head socket cap screws
- Flathead socket cap screws
- Socket set screw
- Hex socket shoulder screws
- Button head socket screws.
Typical Applications of Socket Screws
These durable screws are widely employed for machine parts, clamping, and die-fixturing applications, particularly in hard-to-reach spaces where it is not easy to maneuver devices such as sockets or wrenches. They are also ideal for heavy-duty applications, such as:
- Domestic and Commercial Applications
- Furniture Manufacturing Processes
- Steel Fabrication
- Automotive Sectors
- Aircraft Applications
- Mounting Hinges
- Electronic Applications
- Machine Tooling Applications.
