Wing Screws

What is a wing screw?

Wing screws have machine screw threads and a wing nut styled head. They are meant to permit the screw to be turned into a tapped hole by hand without the use of any tool. They are usually manufactured with a cold formed or stamped wing nut style head.

Wing Screw Applications
Often used when frequent tightening and loosening is required. Though a wing screw can be tightened more than a thumb screw, this is a fastener that is designed to be used manually, it is not suggested for applications where great torque is required. The shank of the Type A version of the screw is case hardened giving it a much greater resistance to abrasion than thumb screws and non case hardened versions.
