M3 Lock Washer Zinc

Ideal for situations where potential loosening from corrosion or vibration is a concern, split lock washers are used to prevent nuts and bolts from coming loose. These fasteners contain split ends that help "lock" into the mating material, thus providing a locking feature when tightened beneath a nut.

• Always use nuts, screws, and washers of a similar finish and screw size
• Parts made of high-strength, class 4.8 steel
• Split ends grip the material surface to prevent loosening during vibration
• Zinc finish for improved corrosion resistance
• This metric lock washer fits a coarse M3-0.50 screw thread
