Hobson WRMSYSM03 M3 Metric Spring Washer, Flat Section
Available
This page lists 10 items of the Hobson metric spring washer, flat section (mild steel, zinc yellow passivate): M3 to M24.
A spring washer is a split ring fitted under a nut or bolt head. In a flat section spring washer the ring is cut from flat strip, so its cross-section is a rectangle.
The supplier item description lists each size as the bolt or screw size followed by further figures without saying which is which. Those figures are shown as listed, and outside diameter and thickness are labelled only where the store option or the Hobson stock list states them.
Pack quantity varies by size and is shown for each item in the table.

Selecting the right option
