Hammond 1421E25W 25-Pack Nickel-Plated Steel Cup Washers

Hammond 1421E25W is a package of 25 metal cup washers — replacement finishing washers from the 1421 Series of 10-32 rack screw and washer kits. It is intended for installers, OEM assemblers, maintenance departments and service technicians who need to top up or replace the decorative washers used when mounting equipment to threaded rack rails.

The washers are constructed of nickel-plated steel and are designed for oval-head screws, seating the countersunk head of a 10-32 oval head rack screw for the clean, finished look traditionally used in audio, broadcast, telecommunications and industrial rack installations. Because the cup shape distributes tightening force evenly over a larger area, it helps reduce the chance of marking equipment faceplates during installation.

1421E25W supplies washers only. The complete 1421 Series kits pair heat-treated 10-32 nickel-plated machine screws with matching washers in 4, 25, 50 and 100-piece packages; this 25-piece washer pack is the metal-washer counterpart to the plastic cup washer replacement pack, so you can restock exactly the component you have run short of.

Each pack has a shipping weight of 0.05 lbs (0.02 kg). The part is RoHS and REACH compliant, USMCA compliant and TAA compliant, with country of origin CA, ECCN EAR99 and tariff code 7318.15.8085. Typical uses for 1421E25W include mounting amplifiers, processors and AV equipment, installing patch panels, switches and cable managers, and replacing worn or missing rack hardware in legacy rack systems.
