Wedge Lock Washer: 0.401" OD, 0.208" ID, Steel, 1010, Zinc-Plated MPN:DL-M5-3/16L-25 - Pkg Qty 25

Wedge lock washers offer superior holding power and load distribution capabilities across various bolted joints compared to traditional flat washers due to their conical design that spreads pressure evenly against the material being fastened. They provide increased resistance to vibration or loosening, perfect for critical structural applications like bridges, heavy machinery, vehicles or any assembly requiring reliable retention of bolts in shear or tension loads. This particular 0.401-inch outside diameter steel wedge lock washer with an internal diameter of 0.208 inches, zinc-plated for enhanced corrosion protection is widely used by aerospace, automotive, marine or construction industries as well as maintenance shops for attaching fittings, brackets, covers or panels securely without the need for adhesives or additional hardware components.
