  • 【Durable Material】These star lock washers are made of 65Mn metal steel with black oxide finish superior rust and oxidation resistance. Our star lock washers are designed for long-term use in harsh environments such as high temperatures, cold weather, and high humidity areas. Our star lock gaskets offer greater tensile strength and heat resistance, as well as longer service life than other common carbon steels.
  • 【Great for Screws & Bolts】Designed with sharp internal teeth, the push on locking washer effectively bite into surfaces and adds a spring force between the fastener and the base plate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, preventing fasteners from rotating or loosening, especially in vibration-prone environments.
  • 【Simple to Use】 The star lock washers have a variety of roles in fixing, supporting and damping, which is used to tighten and loosen threaded fittings. Simply put the locking washers into the screw or bolt. The teeth on the outside of the washer bite down on the screw head and joint to hold it tight. Easy to install and remove and can be reused.
  • 【Wide Application】The star lock washer is one of the indispensable elements in most mechanical equipment, which tighten and loosen threaded fittings, parallel bars or ring gaps to make them stronger. Widely applied in electrical equipment, industrial machinery, automotive and marine, residential construction and housing and other threaded/bolt-type connection.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
