What the 1/4 in Plain Washer does

Sized for the machine’s 1/4-inch fasteners, this plain washer sits under a bolt head or nut and distributes the point load over a wider area. At the CM-WAV’s structural 1/4-20 joints that protects softer molded or sheet parts from being crushed or pulled through and gives the fastener a smooth, flat bearing surface so it torques evenly.

Signs the 1/4 in Plain Washer needs replacing

Replace the 1/4-inch plain washer if it is dished, corroded, or worn so it no longer sits flat, or if it is missing and a 1/4-20 fastener is now bearing directly on a soft part. A cupped washer, or a bolt head that has begun to sink into the plastic, means the washer has failed or was lost and should be renewed.

Installation and fit

Place the new 00851 washer under the 1/4-20 fastener head or nut against the part surface, then tighten so the load spreads evenly. Ensure the washer sits flat and fully under the head.
