custom washer manufacturer: Standard and Custom Washer Offerings
We provide a full spectrum of washer types to meet virtually any application requirement, covering standard, ANSI, and metric flat washers, as well as fully customized non-standard washers. Our standard round flat washers comply with ANSI B 18.21.1 (Type B) and ANSI B18.22M standards, available in narrow, regular, and wide series for screw sizes from 0 to 1” (imperial) and metric specifications with inner diameter (ID) ranging from 1.95 mm to 17.52 mm, outer diameter (OD) from 4.7 mm to 44 mm, and thickness from 0.5 mm to 4 mm. For imperial standard flat washers, we support ID from .020″ to 3.00″, OD from .050″ to 4.00″, and thickness from .010″ to .134″, with infinite combinations of ID, OD, thickness and materials for bespoke needs.
Our custom washer capabilities are unparalleled, with the ability to produce specialty-shaped washers and fasteners including C-shape, D-shape, hexagonal/square hole, off-center hole, rectangular, beveled, countersunk, lock/tab, and spring washers (Belleville, wave, spherical, etc.). We also offer custom precision parts such as dimpled washers, electrical contact washers, and spring retainers, with no tooling charges for non-standard flat washer sizes within our core imperial parameter range (ID .020″-3.00″, OD .050″-4.00″). Beyond washers, we manufacture slotted spring-pins complying with ASME B18.8.2 (diameters 3/32” to 3/8”, lengths ¼” to 3″) and a full line of spacers, gaskets, and plastic circuit board hardware.
Diverse Material Selection for Every Application
We source and process a comprehensive range of metallic and non-metallic materials, ensuring optimal performance for any industrial environment:
- Metallic materials: Aluminum, brass, beryllium copper, copper, phosphor bronze, cold rolled steel, stainless steel (316 included), titanium, with high-strength stainless steel washers featuring low magnetic permeability and corrosion resistance, and copper washers offering excellent sealing, thermal and electrical conductivity. Lightweight aluminum washers (1/3 the weight of steel) are available with color-coded finishes, and phosphor bronze washers can be customized as belleville, bowed, cup, spring, and tension fasteners.
- Non-metallic materials: Acetal, fiberglass, fibre, Kapton, mica, Mylar®, Neoprene, Nylatron®, Nylon, Delrin®, Phenolic, polyethylene, PTFE (Teflon), PVC, rubber, Nitrile, Viton®, SBR. Our plastic washers and fasteners support ultra-precise thickness ranges from .0005″ to .030″, with a full line of nylon washers, spacers, standoffs, and screw insulators available in standard, metric, and custom specifications.
We offer full material flexibility, allowing customers to mix and match any OD/ID, thickness with any material for fully bespoke washers and spacers, all using DFARS compliant materials for added reliability and regulatory adherence.
Advanced Manufacturing & Precision Tolerance Control
HLW leverages state-of-the-art manufacturing facilities and processes to deliver superior precision and quality. Our production capabilities include stamping (for standard thickness custom washers), CNC machining (for non-standard thickness requirements), EDM manufacturing (for specialty-shaped metal fasteners up to 12″ in length, thickness from .001″ to 9″, minimum diameter .050″), laser cutting, and vibratory finishing. We maintain thousands of stock tools for non-standard washers and can produce a custom tool within hours for unique requirements, enabling rapid prototyping and production.
We adhere to strict tolerance controls for all custom washers, with standard precision for key dimensions: OD 1.000 +/- 0.010, ID 0.500 +/- 0.010, and thickness 0.100 +/- 0.010. All manufacturing processes follow certified quality management systems, and we provide full product traceability for every order, ensuring accountability and compliance across the supply chain.
