Trust a lock washer from Grainger to help create tight assemblies. Split lock washers feature a slight spiral design that creates pressure to provide a type of spring action. This allows the washer to grasp adjoining materials and help prevent loosening from vibration. The lock washer selection at Grainger offers a huge range of choices in materials, finish and bolt sizes.
