Access Matters

Most experts agree that a socket head cap screw is your best choice in applications with limited access. Available in a wide range of dimensions, this fastener can be efficiently adjusted with tools from a standard socket set, which require very little clearance around the fastener.

Socket head cap screws are also considered to have a more modern appearance, although this is subjective. Technical equipment and electronics often use socket head cap screws, creating a visual association that may carry over to other products and applications.

Some professionals choose to use the socket head style due to quality issues or repeated stripping with hex head cap screws. Others claim that socket head cap screws round out easily, while it takes extreme pressure with repeated use to round off hex head styles.

Watch For Debris

Debris presents a common problem when using socket head cap screws. Soft materials or tiny particles may clog up the socket, making it difficult to work with these fasteners and possibly resulting in premature wear for the joint.

Hex head cap screws present a solid head that can be easily adjusted using a variety of wrenches, including an adjustable, socket or box head wrench. Debris build up is less of an issue with this style of fastener.

Both the hex head cap screw and socket head cap screw create a strong, stable joint. Depending on the access in your application, your visual preferences, and the presence of debris, one may be better than the other.
