While most screws have the same basic design, different types provide different benefits. From drywall screws and deck screws to concrete screws and machine screws, each style is made with unique features to provide the torque and hold strength required for your intended application. Important considerations to keep in mind include:

• Head style and driver style
• Material and coating requirements
• Size and length
• Thread pitch
• Load bearing capabilities
• Temperature & corrosion resistance

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.
