Value Collection 02WI188 Internal Tooth Lock Washer

Product Description

The VALUE COLLECTION 02WI188 is a 2 screw internal tooth lock washer made from Grade 18-8 stainless steel. Designed to prevent fastener loosening under vibration and torque loads, the internal teeth bite into the bearing surface of the fastener head and the mating workpiece to maintain clamp force. With an inside diameter of 0.095 inches and an outside diameter of 0.2 inches, this washer is sized for small-fastener applications where space is limited. A thickness of 0.016 inches keeps the profile low while maintaining functional tooth engagement. Trade professionals and assembly technicians specify this style when corrosion resistance and reliable locking performance are both required in a single component.

This internal tooth lock washer is suited for light-duty fastening applications in HVAC, electrical, plumbing, and pool equipment assemblies where stainless steel is required for corrosion resistance. It is commonly installed beneath machine screws and pan-head fasteners in control panels, enclosures, brackets, and equipment frames. The 18-8 stainless steel grade makes it appropriate for environments with moisture exposure or mild chemical contact. These washers are sold in multiples of 100, making them a practical stock item for service vehicles and shop bins.

Key Features

• Internal tooth design grips both fastener head and workpiece surface to resist loosening from vibration
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Inside diameter of 0.095 inches fits 2 screw fasteners precisely
• Low-profile 0.016 inch thickness suits tight clearance assemblies
• Outside diameter of 0.2 inches keeps footprint compact for small-fastener applications

Compatibility

Designed as an OEM-style replacement or stock fastener component for 2 screw applications requiring an internal tooth lock washer in stainless steel.

Installation Notes

Installation is performed by general mechanics, electricians, and HVAC or plumbing technicians during equipment assembly or service. Always de-energize and lock out equipment before accessing fastened assemblies inside electrical enclosures or control panels. Place the washer flat against the workpiece surface with the teeth facing the fastener head before driving the screw. Do not reuse lock washers that show deformed or flattened teeth, as locking effectiveness will be reduced.
