Button Head Screws

What are Button Head Screws?

Button Head Screws feature a low-profile domed head. Due to their unique head shape, these fasteners are sometimes called Dome Screws or Round Head Screws. Button Head Screws have a relatively large head diameter, which allows for a larger drive type to be used. A larger drive is capable of exerting more torque during installation, and is particularly useful on components such as Slotted Button Head Screws, where the drive spans the diameter of the head. The head of these components is also free from pointed edges, adding to their safety and aesthetic appeal.

Accu's range includes a number of varieties of Button Headed Screw, including Flanged Button Head Screws, Hexagon Socket Button Head Screws, Torx Button Head Screws, and Slotted Button Head Screws. Accu also stock a variety of Driver Bits for use with these fasteners.

Button Head Captive Screws.

Accu's range of high precision Button Captive Screws provide a safety fastener solution to help prevent fastener loss in assemblies with high safety standard requirements. They are designed to be used in conjunction with a Captive Washer, which locks to the unthreaded shank of the captive screw when fastened together, preventing the screw from being fully removed.
