External Tooth Lock Washer M16

Zoro Select M37302.160.0001 supplies one hundred external tooth lock washers sized for M16 fasteners. The spring steel construction rated at 350 to 425 HV10 resists vibration loosening in general purpose assemblies. Zinc plating provides corrosion protection for indoor and sheltered outdoor use. Each washer measures 17.0 mm inside diameter, 26.0 mm outside diameter and 1.20 mm thickness.

DIN 6797 A Compliance

The washers meet or exceed DIN 6797 A, confirming dimensional accuracy and mechanical performance for standard metric joints. This standard governs tooth geometry, hardness and coating quality so the parts behave predictably under clamp load. Buyers specifying to this norm can install without additional verification. The bulk pack simplifies inventory for maintenance crews and assembly lines.

M16 Fastener Fit

These washers fit bolt size M16 only; they will not seat correctly on smaller or larger metric threads. The 17.0 mm inside diameter matches the M16 shank while the 26.0 mm outside diameter distributes load across the joint face. Engineers needing a different screw size or an internal tooth pattern must select another part number.

Questions about this item

Will the zinc plating on these M16 washers wear off and require replacement?

The zinc-plated spring steel resists corrosion under normal conditions; replacement is only needed if the plating is mechanically damaged or the teeth lose their bite.

What stops these washers from working after repeated vibration cycles?

The external teeth are hardened to 350-425 HV10; they maintain grip until the teeth physically deform or the 1.20 mm thickness yields under extreme load.

Do these M16 lock washers generate heat or noise when used continuously in vibrating assemblies?

As passive steel components they produce no heat or noise; they simply maintain clamping force through their 17.0 mm inner and 26.0 mm outer diameter teeth.
