Description
Overview:
These Metric Spring Washers have a 5 mm inner diameter and come in a bulk pack of 1000 for workshop and site use. Made from steel with a bright zinc-plated finish, they are split (helical) washers with a rectangular cross-section that provides a spring action to help keep bolted joints tight. Use them under a nut or bolt head to resist loosening from vibration and thermal cycling. They are suitable for M5 fasteners in construction equipment, garden machinery, small engines, pumps, brackets, and general fabrications. The zinc plating offers good corrosion resistance for indoor and outdoor service. Supplied under MPN 903 1050, these washers are a practical stock item for maintenance engineers, mechanics, and DIY users who need consistent, reliable fixings in quantity.
Key Features:
- 5 mm inner diameter to suit M5 bolts and set screws
- Split, rectangular-section design provides spring tension to resist loosening
- Zinc-plated steel for corrosion resistance and long service life
- Helps maintain clamping force in vibrating or dynamic assemblies
- Easy to fit: place between the nut/bolt head and the joint surface
- Works alongside plain (flat) washers to spread load while adding anti-rotation security
- Clean, consistent sizing for repeatable assembly results
- Bulk pack of 1000 for efficient stocking and reduced downtime
Typical Applications:
Used wherever bolted joints are exposed to vibration or movement, including machinery guards, engine covers, pump housings, generator frames, plate compactors, lawn mowers, strimmers, conveyors, metal fabrications, brackets, fixtures, racking, and panels. Suitable for workshop maintenance, plant repairs, and general assembly on steel or aluminium components.
