It's just nice when you get what you ordered, saving [me] time and a trip to my local Staples drop-off return. ## Frequently Bought Together - 1-1/4" x 2.5"OD Flat Washer, 18-8 (304) Stainless Steel Washers Flat, 2PCS - Instockbolt 3/8" x 0.68"OD Split Lock Washer, 18-8 (304) Stainless Steel Spring Lock Washer 50PCS - Vifmy Locknuts Assortment Kit,M3 M4 M5 M6 M8 M10 M12 140PCS Metric Nylon Insert Lock Nuts Set,304 Stainless Steel Lock Nuts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/733135410-1-1-4-x-2-5od-flat-washer-18-8](https://www.desertcart.be/products/733135410-1-1-4-x-2-5od-flat-washer-18-8) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-17*
