About us

For nearly 100 years, Brewster Washers has been manufacturing flat washers, shims, discs, and more recently, specialty flat odd-shaped parts as well as parts with multiple holes. We typically work with material tolerances that are .0005" on thickness and +/- .005" to .001" on Inside Diameters (ID) and Outside Diameters (OD).

Our washers and specialty metal parts are made from a variety of materials: both pre-tempered and annealed Steel; Stainless Steel in all grades and hardness specifications; Copper; Brass; Aluminum; Phosphor Bronze annealed and hardened as well as semi-exotics such as Inconel, and Monel. We also manufacture parts from PTFE, Nylon, Nylatron, and plastics in a variety of colors to meet customer specifications.

Brewster Washers manages all aspects of the manufacturing process within its Fairfield, NJ facility: from receiving raw material and incoming inspection, to tool building, stamping, deburring, and final inspections. We work with local firms to perform specialty inspection processes such as Magnetic Particle Inspections, FPI, post-production plating, lapping and polishing to customer specific thicknesses. All operations are integrated into our manufacturing process and copies of all certifications are available when required.

Unlike traditional washer manufacturers who produce washers that conform to either USS, SAE, DIN or other standards, Brewster specializes in manufacturing custom parts while conforming to the customer's specifications or blueprints. We never charge for tooling on orders, or have any minimum quantity requirement.

Brewster Washers is proud to be an ISO9001:2008 Certified Quality Systems Company.
