FAQ:
Q1: What is the difference between a machine screw and a wood screw?
A: Machine screws, like the Cross Recessed Pan Head Machine Screw, are designed with finer, more precise threads intended for pre-tapped holes in metal or to be secured with a nut. Wood screws have coarser threads designed to bite directly into soft materials.
Q2: What are Cross Recessed Pan Head Machine Screws used for?
A: They are commonly used to fasten components in pre-threaded holes or with nuts in electronics, appliances, and general machinery assemblies.
Q3: Do I need specialized tools for installation?
A: No. These screws feature a standard Phillips cross-recess drive, which is compatible with most manual or powered Phillips-head screwdrivers.
Q4: Can these screws be used in a "flush" application?
A: While the pan head is rounded and sits slightly above the surface, it provides a very clean, low-profile finish that is suitable for most aesthetic applications where a completely flat countersunk head is not required.
Q5: Does the pan head sit flush after installation?
A: The pan head typically sits slightly above the surface, providing a smooth, rounded finish rather than a fully countersunk appearance.
