washers, shims & spacers
Built for controlled spacing, alignment, load distribution, and dimensional adjustment.
Gromax manufactures precision flat stampings used to control spacing, alignment, clearance, load distribution, tolerance stack-up, and component position within mechanical and electromechanical assemblies.
We review material, thickness, profile, hole geometry, flatness, edge condition, tolerances, finish, and assembly requirements to support consistent fit and repeatable production.
part examples
Flat Washers
Precision annular or shaped stampings used to distribute load, provide bearing surfaces, isolate components, or control spacing beneath fasteners and mating parts.
Precision Shims
Thin flat stampings used to adjust dimensional stack-up, alignment, preload, clearance, or component position within an assembly.
Custom Spacers
Flat stamped parts used to establish a controlled separation or stand-off distance between mating components.
Tab & Keyed Washers
Washers with tabs, flats, keys, slots, or other locating features used to control orientation, prevent rotation, or engage adjacent components.
Slotted & Profiled Shims
Non-round shims with slots, cutouts, notches, or custom profiles designed to fit around shafts, fasteners, housings, or other assembly features.
Bearing & Thrust Washers
Flat stamped components used as bearing surfaces or axial load interfaces where material, hardness, finish, lubrication, and mating conditions are appropriate for the application.
Not sure where your part fits?
part design essentials
Reliable washer, shim, and spacer performance depends on how thickness, flatness, profile, edge condition, and the mating assembly work together.
Thickness & Tolerance
Material thickness often directly controls spacing, preload, clearance, or stack height, making thickness consistency and tolerance especially important.
Flatness & Distortion
Residual strip stress, stamping forces, part geometry, and handling can affect flatness, bow, or dish, particularly on thin or large-diameter parts.
Hole & Profile Geometry
Inside diameter, outside profile, slots, notches, tabs, and keying features must match the functional interface and intended assembly method.
Load & Bearing Area
Washer diameter, thickness, material strength, and contact area should suit the applied load and mating surface to limit excessive deformation or localized bearing stress.
Edges & Burr Direction
Burr height and orientation can affect seating, stack-up, sliding interfaces, sealing surfaces, and contact with softer mating materials.
Material & Finish
Strength, hardness, corrosion resistance, conductivity, wear behavior, and environmental exposure influence material and plating or coating selection.
from DfM to Production
Gromax supports washer, shim, and spacer programs from drawing review through repeatable production.
Part & DfM Review
Review the drawing, function, material, thickness, flatness, profile, hole dimensions, tolerances, finish, assembly conditions, and production volume.
Progressive Die Design & Build
Develop tooling for the required piercing, blanking, notching, slotting, coining, embossing, and cutoff operations.
Precision Stamping
Establish a repeatable process around thickness-sensitive features, inside and outside profiles, hole location, concentricity where required, and dimensional consistency.
Finishing & Secondary Operations
Incorporate deburring, plating, coating, heat treatment where applicable, cleaning, sorting, or assembly into the production plan.
Production Support
Support ongoing programs with tool maintenance, dimensional review, material evaluation, process monitoring, root-cause analysis, and corrective action.
quality & assembly fit
Inspection should verify the characteristics that determine whether the part seats, spaces, aligns, and functions correctly in the finished assembly.
Material Thickness
Material thickness and finished stack contribution where dimensionally critical.
Flatness & Form
Flatness, bow, dish, and distortion where specified.
Hole & Profile Dimensions
Inside diameter, outside diameter or profile, slot width, notch geometry, and feature location.
Edges & Surface Condition
Burr direction, edge quality, scratches, dents, plating or coating coverage, and cleanliness.
Assembly Fit
Seating condition, clearance, alignment, stack-up contribution, and fit with fasteners, shafts, housings, bearings, or adjacent components.
Gromax checks critical dimensions using standard measurement, optical inspection, fixtures, custom gaging, or functional inspection methods and reviews your certification, traceability, and inspection documentation needs.
