    • High-Quality Stainless Steel Washers – Simple Yet Essential! ⭐⭐⭐⭐⭐
I purchased these 1/4" Stainless Flat Washers for a home project, and they truly exceeded my expectations. Despite being a simple component, washers play a crucial role in ensuring a secure and stable assembly. The 5/8" outside diameter and 18-8 (304) stainless steel construction provide excellent durability and corrosion resistance, making them perfect for both indoor and outdoor applications. The pack of 100 is a fantastic value, and I've found them to be reliable every time I use them. Whether you're working on a DIY project or professional installation, these washers are a must-have! ✅ Perfect size for secure assemblies ✅ Durable, corrosion-resistant stainless steel ✅ Great value with a 100-pack Highly recommend these washers for any project that demands reliability and quality! ... show more

    • Useful for support behind screws and bolts 1/4 diameter.
Should be good for extra backing for 1/4 inch screws and bolts in miscellaneous uses. Versatile. Thick enough for light work appear good size should be useful. Durable and hopefully rust resistant.
