In this article John covers some basic tips and tricks when working with Flat Head Screws. He also explains some of the differences between the six different types of flat heads available, including:
Socket Cap Screw Heads – A style unique to socket drive screws, these are installed flush with the surrounding materials, providing a smooth appearance and easy access to the drive. Often used as finishing screws for carpentry and woodworking.
Trim Head – An option to a flat head, this provides a narrower head making the fastener less visible after installation. Frequently found in woodworking projects and carpentry.
Binding Undercut – Commonly found in electrical applications, this head design features an undercut channel which allows for the incorporation of wire connections underneath the head of the screw. This provides a stronger, more secure connection which increases electrical conductivity and reduces the potential for corrosion.
Oval Head – Similar to a flat head, this design has an oval dome section on top which sits proud of the workpiece when seated, giving it a more finished and aesthetic look. This head is commonly used in furniture and handles, and can be utilized with a variety of drives. Frequently abbreviated OVAL.
Whether you are installing new Fasteners or loosening and removing existing ones, the proper use of a screwdriver can make all the difference in ensuring you get the job done right. Be sure you have the correct size screwdriver for your application, and be sure to properly align the tip of the screwdriver with the slot in the fastener head. This will help to prevent slippage and stripping of the head or shaft. Flat Head Screws
