Socket head cap screws are a special type of fastener that is typically used in machine parts, die fixturing, and clamping. These screws are ideal for applications in which there is not enough space to maneuver wrenches or sockets. Located in Canton, MA, Electronic Fasteners can help you select the correct screw to ensure that your project is completed correctly and securely. Otherwise, you may face issues with the strength and stability of your construction.
There are a few different types of socket head screws cap screws, available, each with its own benefits:
- Ones with nylon pellets typically feature an internal hexagon drive (Allen head) that offers extra locking strength in the form of a small nylon pellet that’s applied to the threads to prevent loosening through vibration. It features a tall head and high strength.
- Screws with a nylon patch perform the same function as the pellet. Like the previous screw, this one is tall-headed, internally driven, and high-strength.
- Screws with a full thread are another tall-headed, internally-driven high-strength fastener. The entire length of the shank is threaded, hence the name.
- Socket head screws with a drilled head feature a hole drilled in the head to accept a wire thread as a safety feature.
Socket head cap screws are also referred to as socket head bolts. Standard inch series socket head screws are 20 percent stronger than a Grade 8 hex head screw and 50 percent stronger than a Grade 5 hex screw. The tensile strength is a minimum of 180,000 psi for sizes 1/2′ diameter and smaller and 170,000 psi for 5/8′ diameter and above. Tensile strength may vary according to heat treatment and manufacturer, which means that when you are looking for the ideal screw, you want to factor in the environment the fastener will be placed in as well as the expected level of stress it will experience. Low head, flat head, and button head screws—unlike socket head screws—are rated 10,000 psi lower due to the head configuration and are seen more in lighter-duty applications. This makes socket head screws perfect for heavier-duty projects that require a higher level of strength and security.
