What the 8-18 x 1/2 in Hi-Lo Screw does

A hi-lo screw has alternating tall and short thread crests designed to form and grip strong threads in plastic, so it holds far better in a molded boss than a standard machine screw. On the CM-WAV this #8 x 1/2-inch pan-head hi-lo screw fastens covers and housings into plastic bosses, and its black-zinc finish matches the machine and resists corrosion.

Signs the 8-18 x 1/2 in Hi-Lo Screw needs replacing

Replace this screw if the boss it threads into has stripped and it no longer holds, if the pan head or Phillips drive is chewed, or if the finish has corroded. Because hi-lo screws form their own thread, repeatedly reusing one in the same plastic boss can wear the hold; renew the screw (or the part with a fresh boss) if it spins free.

Installation and fit

Drive the new X8849 screw into its molded boss along the existing thread it formed, straight and without over-torquing, until the cover or housing is held snug. Do not overtighten, which strips the plastic boss. Twin City Vacuum has sold and serviced CleanMax equipment since 1956, and every part is sourced directly from Tacony.
