Uxcell #10 Split Lock Washer, 200 Pack 4.9mm ID 8.2mm OD 304 Stainless Steel Spring Lock Washer Gasket, Silver Tone

Split lock washers are designed to split the load of a screwed fastening and prevent loose, and are widely used in industrial, bathroom, electronics, furniture, mechanics, and home appliances.

Advantage
Made of 304 stainless steel features wear-resistant, corrosion-resistant, rust resistance, and oxidation resistance. 304 stainless steel lock washers provide greater bolt tension for tighter installation and provide protection from loosening of vibration. Lock washers can be used with a standard washer to provide better effect.
Split lock washers are used with same-size screws, nuts, and bolts featuring tight connections to prevent the nut or bolt head from tearing through the material and providing a support surface for fasteners.

Instruction
Place the washer between the item to be fixed and the bolt, and tighten the bolt.

NOTE:
Please choose an appropriate diameter so as not to affect its fasten performance.
