Why choose a Serrated Flange Screw?
Serrated Flange Screws can provide cost saving during the installation process by using only one fastener to lock your product into place. With an increased contact area and strong holding power, there's no need for a separate washer.
The serrations located under the head, lock onto the surface once tightened, ensuring that the material being clamped to provides excellent resistance to loosening caused by vibration.
