Most screws have the same basic design featuring a head and threaded shaft, but each style has a different use. There are drywall screws, deck screws, masonry & concrete screws, and machine screws, each with various features to provide the torque and hold strength required for the intended application.
Selection criteria for finding the right screw fastener include:
- Head style and driver style
- Material and coating requirements
- Size and length
- Thread style
Additional considerations include the need for self-drilling or self-tapping screws, and whether you need a permanent or temporary hold. View our Fastener Specs for additional dimensional and technical data for our screw fasteners and other products.
