Spanner & Drive for M16 Fender Washers

Drive geometry for M16 Fender Washers is given by the row above; match the tool to the listed values.

Common Applications for M16 Fender Washers

M16 Fender Washers are commonly specified for medium-duty structural joints.

Mating Parts for M16

A M16 flat washer pairs with a M16 bolt/screw and matching M16 nut.

When to Step Up or Down from M16

When the joint preload approaches the proof load of M16 class 8.8, step up to M20 class 8.8 (or move to M16 class 10.9). When the joint is over-specified, M12 often saves weight and cost without losing the safety margin.

Frequently Asked Questions

Which washer dimensions matter most for M16?

For a flat washer, the outside diameter (the bearing surface) and the thickness control how the load is spread under the head and how much elastic preload is preserved. The inside diameter must clear the bolt body but not be so large that the head bears mostly on the washer's outer rim.

What is the coarse-thread pitch of M16 for Fender Washers?

For M16 the standard coarse pitch is 2 mm — this is the value used for Fender Washers.

What clearance and tapping drill suit M16?

Use a 17.5 mm clearance hole (ISO 273 medium) for through-fixing, or a 14 mm tapping drill for a coarse M16 thread.
