Description
733 fender washer is a Chem-Set washer pack for sink fastening and light hardware assemblies where load needs to be spread under a nut or bolt head. The master product record lists a 1/4 x 0.75 inch size, extra-thick construction, corrosion resistance, and a 25 piece quantity for the CCH733 listing.
733 fender washer Applications
- Distributing clamp load under sink mounting hardware.
- Adding bearing area on countertop fabrication assemblies.
- Supporting light construction hardware where a standard washer is too small.
- Replacing worn washers in shop kits, install vans, and sink fastening bins.
- Helping reduce pull-through risk on thinner brackets or softer backing materials.
Fender washers have a larger outside diameter than many flat washers, so they are useful when the fastener head or nut needs more bearing area. Confirm the screw or bolt diameter, outside diameter, material stack, and clearance before installing. The washer should sit flat, without rocking on debris, burrs, or cured adhesive.
Keep this pack with the related sink clip, bracket, and insert inventory so installers do not mix mismatched hardware on site. If the assembly is exposed to water, cleaners, vibration, or repeated load cycles, confirm washer material and corrosion needs before final installation. Replace any washer that is bent, distorted, or gouged. Record the size and mating hardware on the job traveler for repeat crews.
