Washers are critical components in mechanical assemblies that prevent joint failure, extend equipment life, and ensure safety across industries. Beyond their simple appearance, these small discs distribute loads, dampen vibration, resist corrosion, and maintain fastener integrity. At G-Fast, we manufacture premium USA-made washers engineered to exacting standards. Whether you need wave washers for vibration control, Belleville washers for heavy loads, lock washers for anti-rotation, or flat washers for general-purpose applications, our comprehensive selection serves manufacturers, contractors, and maintenance teams nationwide.
Why Washers Matter in Industrial Applications
Washers serve multiple critical functions:
Load Distribution – Spreads force across a wider surface area, preventing fasteners from sinking into soft materials like aluminum or plastic.
Vibration Damping – Absorbs shock and oscillation, maintaining bolt tension in dynamic environments and preventing loosening over time.
Corrosion Protection – Stainless steel washers resist rust and chemical exposure in harsh environments.
Alignment & Spacing – Shim washers enable precise spacing in machinery requiring tight tolerances.
Choosing the correct washer type is essential for structural integrity, reliability, and safety.
Types of Industrial Washers
Flat Washers – The Foundation
The most widely used type, flat washers distribute load evenly and prevent fasteners from pulling through soft materials. Available in SAE, USS standards, and multiple materials (carbon steel, stainless, brass, bronze).
Best For: General construction, automotive manufacturing, plumbing, light to medium-load applications.
Lock Washers – Prevent Fastener Loosening
Featuring irregular tooth surfaces, lock washers create friction and mechanical resistance to prevent vibration-induced loosening without additional components.
Best For: Automotive engines, vibrating machinery, electrical assemblies, applications requiring frequent disassembly.
Wave Washers – Compact Vibration Control
Wave washers feature an undulating profile providing spring-like action in limited axial space. They compensate for small clearances while maintaining consistent clamping force.
Best For: Electric motors, medical devices, consumer electronics, space-constrained applications.
Belleville Washers – High-Load Spring Action
Conical-shaped Belleville washers (disc spring washers) act like springs when compressed, supporting exceptionally high loads with minimal deflection. Temperature range: -400°F to 1,100°F. Stackable in series or parallel for customized performance.
Best For: Automotive transmissions, heavy machinery, thermal cycling applications, high-vibration equipment.
Stainless Steel Washers – Corrosion Resistance
Available in 304 (general-purpose) and 316 (marine-grade, chemical-resistant) grades, stainless washers are essential for demanding environments.
Best For: Food processing, water treatment, marine equipment, medical devices, outdoor construction.
Structural Washers – Heavy-Duty Load Bearing
Thick, hardened washers designed for structural steel connections in bridges, high-rise buildings, and infrastructure projects. Meet ASTM F436 standards.
Best For: Bridge construction, structural fabrication, heavy equipment supports, transmission towers.
Shim Washers – Precision Spacing
Manufactured to tight tolerances, shim washers enable precise spacing and machinery alignment without modification.
Best For: Aerospace manufacturing, tool and die work, heavy machinery calibration, precision engineering.
Thrust Washers – Axial Load Support
Flat or tapered bearings designed to support axial loads and reduce friction between moving parts. Available in bronze, stainless steel, and nylon.
Best For: Gear systems, automotive transmissions, pumps, compressors, power tools.
Fender Washers – Large-Surface Distribution
Extra-large outside diameter relative to bolt size, preventing fasteners from pulling through thin materials or soft surfaces.
Best For: Automotive panels, thin sheet metal, composite panels, equipment mounting on delicate surfaces.
Industrial Washers Material Selection Guide
Carbon Steel & Hardened Steel – Cost-effective for indoor, dry environments. Good vibration resistance. Requires coating for outdoor use.
Stainless Steel (304 & 316) – Superior corrosion resistance for food, pharmaceutical, and marine industries. Higher cost justified by longevity.
Brass & Bronze – Non-magnetic, excellent corrosion resistance, ideal for electrical and marine applications.
Specialty Materials – Nylon and plastic for electrical insulation; rubber compounds for sealing; exotic alloys for extreme temperatures.
Standards & Specifications of Washers
Industry standards ensure proper fit, safety, and compatibility:
- SAE – Automotive and general applications
- ASTM F436 – Structural washers for heavy-duty applications
- ANSI – Metric and imperial fastener specifications
- DIN 9021 – European flat washer standards
- ISO 4759-1 – International metric specifications
G-Fast products conform to applicable industry standards, ensuring compatibility with your specifications and regulatory requirements.
How to Select the Right Washer
- Determine load type – Static vs. dynamic, magnitude, shock/vibration requirements
- Assess environment – Temperature range, chemical exposure, moisture, weathering
- Evaluate space – Axial constraints, bolt diameter, OD restrictions
- Consider assembly frequency – Permanent vs. frequent disassembly, thermal cycling
- Match material – Corrosion resistance, temperature needs, cost analysis
- Verify standards – Industry requirements, building codes, customer specifications
