GB855 Tab Washers With Two Tabs – 304 Stainless Steel Locking Washer, M8 (50-Piece), Double Wing Design

About This Product

These GB855 tab washers are designed for locking applications where you need to keep nuts or bolts from backing out.

Each washer has two tabs (wings) that you bend up against the fastener after tightening – that provides a positive mechanical lock that won't loosen from vibration or movement.

The 304 stainless steel construction gives you excellent corrosion resistance, so they're good for indoor, outdoor, or even marine-adjacent environments.

This pack gives you 50 pieces, all M8 inner diameter.
They meet GB855 standards, which is a common Chinese national standard for tab washers.

DIY supplies category – they're often used in electrical equipment, mechanical assemblies, and general fastening applications where security matters.

Sturdy, reliable, and easy to use – just slide one on, torque the nut, then bend one or both tabs into place against a flat surface of the nut or bolt head.

No special tools needed beyond pliers.

Good to have on hand for maintenance, repairs, or assembly work.
