Why Washers Matter in Your DIY Projects
Washers may seem like small, unassuming components, but they play a critical role in preventing leaks, reducing friction, and distributing load pressure in everything from plumbing systems to furniture assembly. At HomeDIYer, we stock over 50+ washer types to ensure your projects stand the test of time.
Pro Tip: Using the wrong washer (e.g., a flat washer instead of a lock washer) can lead to loose bolts and safety hazards.
Types of Washers We Offer
1. Flat Washers
- Best for: General-purpose use under bolts/nuts
- Materials: Stainless steel (rust-resistant), nylon (electrical insulation)
- Common Sizes: #8, 1/4", 3/8" (view size chart)
2. Lock Washers
- Split Lock Washers: Ideal for automotive engines or machinery with vibrations

How to Choose the Right Washer: 3 Key Factors
Factor 1: Material Compatibility
- Outdoor Projects: Stainless steel or galvanized steel washers resist corrosion
- Electrical Work: Non-conductive nylon washers
- High-Temperature Areas: Copper washers (e.g., BBQ grill repairs)
Factor 2: Size & Thickness
Always match the washer’s inner diameter to your bolt size. Example:
- 1/4" bolt → 1/4" ID washer
- Thicker washers (3mm+) handle heavier loads like garage shelving
Factor 3: Load Type
- Static Loads: Flat washers work well (e.g., bookshelves)
- Dynamic Loads: Lock washers prevent loosening (e.g., ceiling fans)
