Wing bolt

Wing bolts, also known as thumb screws or butterfly bolts, are threaded fasteners designed for manual tightening and loosening without tools. These components feature two large, flat wings or tabs protruding from the head, providing a high-torque grip for hand operation. Typically manufactured from steel, stainless steel, or brass, wing bolts come in various thread sizes (e.g., M4, M5, M6, M8, M10) and lengths, with metric or imperial threads. They are commonly used in applications requiring frequent adjustment or temporary fastening, such as in machinery guards, electrical enclosures, or panel assemblies. The wing design allows for quick installation and removal, reducing downtime in maintenance tasks.

Wing bolts are widely applied in industrial sectors including electrical panel manufacturing, automation systems, HVAC installations, and general machinery assembly. They are ideal for securing covers, doors, or access panels in control cabinets, distribution boards, and electrical enclosures where tool-free access is needed. In automation, they facilitate rapid component changes in conveyor systems or robotic cells. Their use extends to automotive, aerospace, and furniture industries for adjustable fixtures and temporary supports.

Key subcategories include standard wing bolts, wing screws with captive washers, and wing nuts. Common article codes follow patterns like WB-M6-20 for a wing bolt with M6 thread and 20mm length, or SS-WB-M8-30 for stainless steel variants. Other codes may include WB-M5-12, WB-M10-25, and WB-1/4-20 for imperial threads. These codes typically combine material, thread size, and length identifiers.
