Hardware for Export: Precision matters when sourcing washers for international construction projects. This comprehensive, authoritative guide helps UAE hardware shopkeepers and construction exporters understand the most popular washer types and sizes stocked locally.
✅ What Are Washers & Why They Matter in Construction
Washers are thin plates—typically round or square—with a central hole designed to evenly distribute the load of threaded fasteners (like bolts and nuts). In construction, they:
- Protect surfaces from damage due to torque.
- Distribute load to prevent material deformation.
- Prevent loosening from vibration (with lock-washer types).
- Serve as spacers, sealers, or wear pads. lktuae.com+15Wikipedia+15husainibrothers.com+15ACE UAE

- Include square washers (M8–M72) to cater to timber and civil works.
- Offer specialty metals (brass, stainless steel A2/A4, MS with coating).
- Bundle bulk packaging (e.g., 1,500-piece boxes for M20) to meet larger orders.
- Label by standard (DIN, ISO, ANSI) to help international procurement teams.
🛠️ Best Practices in Selection & Maintenance
- Match washer type to fastener and substrate—use thick or square washers for heavy-duty or expansive surface loads. exceltradinguae.com+2husainibrothers.com+2misar.ae+2Accu+2Monster Bolts+2mfindllc.com+2mfindllc.com
- Use hardened washers for high-preload bolting where brinelling is a concern. Wikipedia
- Inspect regularly for signs of wear—replace washers when dents or corrosion appear. husainibrothers.com
