Heavy Duty Wing Nut — High-Strength Steel Fastener with Large Wings for Hand Tightening

This Heavy Duty Wing Nut is engineered for durability and ease of use in demanding applications. Crafted from premium-grade steel (or stainless steel, depending on variant), it features oversized “wings” that allow rapid hand tightening and loosening—no tools required. Ideal for machinery, equipment panels, jigs, fixtures, and anywhere repeated assembly/disassembly is needed under load.

Its robust construction resists wear and deformation under torque, while anti-corrosive finishes (zinc plated, black oxide, or stainless) provide long service life even in humid or outdoor settings. Whether you’re securing molds, clamps, or panels, this wing nut delivers reliable, heavy duty performance.
