DIN316 Wing Screws

DIN 316 Wing Screws are made for fastening points where the convenience of hand operation matters. Their wing-shaped heads provide enough grip to tighten or loosen the screw directly by hand, eliminating the need for a screwdriver or wrench during routine access and adjustment. This makes them particularly useful for covers, guards, fixtures, panels, and other components that may need to be opened or repositioned without specialized tools.

The design is especially practical in equipment that requires frequent access, temporary fixing, or on-site adjustment. Instead of carrying a separate tool to release a conventional screw, an operator can grip the wings and make the adjustment directly. The screw is therefore better suited to moderate clamping requirements where speed, accessibility, and ease of operation are more important than applying high tightening torque. DIN 316 Wing Screws can be used in machine covers, equipment panels, inspection openings, fixtures, instrument housings, and general mechanical assemblies.

Specification:

DIN 316 Wing Screws use a machine-threaded shank with an integrated wing-shaped head, allowing the fastener to be tightened or released manually. The head dimensions provide the gripping area, while the threaded section determines compatibility with the mating nut or internally threaded component. Screw length is available according to the required clamping thickness and thread engagement.

For material and finish, carbon steel can be used for general mechanical assemblies, with zinc plating available when additional corrosion protection is required. Stainless steel versions are suitable for applications exposed to moisture or corrosive environments and can be supplied with a plain or passivated surface.

Dimension Chart of DIN316 Wing Screws:

The DIN 316 dimension chart covers the main measurements that define the screw and its hand-operated head. In addition to the thread diameter and screw length, the wing dimensions are important because they determine the available gripping area and the clearance required around the fastener. The thread dimensions should match the mating nut or internally threaded component, while the screw length should provide sufficient engagement for the intended connection.

For installation in compact equipment, the wing width and head height should be checked against the surrounding components to ensure that the screw can be comfortably accessed and rotated by hand. The dimensional drawing below provides the reference measurements for comparing different DIN 316 sizes.
