The Screw is an OEM part for Frigidaire ranges and ovens. This part is designed to securely fasten various parts of the appliance, ensuring stability and durability. 

Over time, screws can become loose due to the expansion and contraction of materials with temperature changes. Regular use and the occasional necessary removal for repairs or cleaning can also wear down the threads, making them less effective.  

Symptoms of a bad Screw (Chrome) include:

• Loose or wobbly components that should be securely fastened.
• Difficulty in securing parts due to stripped or damaged screw threads.
• Visible corrosion or deterioration of the screw.

This OEM Frigidaire part can also be used on Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore.

Size: 8-18 x 0.5 inch. Color: Chrome.
