Washer Tab Locker

The Winters Washer Tab Locker (part number 1589) is a precision-engineered tab lock washer designed to prevent fastener rotation and loosening under vibration or thermal cycling. This cadmium-plated steel lock washer measures 0.062 inches in thickness and features a distinctive tab design that engages with the fastener head or surrounding surfaces to provide positive mechanical locking without relying on friction or spring tension alone.

Tab lock washers like this model excel in applications where vibration, shock, or temperature fluctuations would otherwise cause standard washers or spring locks to fail. The cadmium plating provides corrosion resistance suitable for harsh outdoor environments, including exposure to moisture and mild chemical exposure. The 0.062-inch thickness balances structural integrity with compatibility across a wide range of fastener sizes, making this washer adaptable to both light-duty assembly and demanding industrial or field applications where fastener security is non-negotiable.

This lock washer is ideal for users assembling equipment, machinery, or structural components where fastener failure could compromise safety or performance. Tactical and industrial professionals, maintenance teams, and equipment manufacturers rely on tab lock washers to secure critical bolted connections in vehicles, firearms platforms, machinery, and outdoor gear. The individual unit format allows exact quantities to be selected for specific projects without waste, and the cadmium plating ensures longevity in field conditions.

Winters is recognized for producing reliable fastening hardware and components built to withstand demanding applications. The Washer Tab Locker SKU WIN1589 represents the brand's commitment to precision fastening solutions. When fastener security matters, a properly sized and installed tab lock washer prevents costly equipment downtime and potential safety hazards associated with loose connections.
