Internal Tooth Lock Washers

Good for use with small-headed fasteners, such as high-profile fillister and cheese head machine screws, the internal tooth lock washer is designed with internal teeth that digs into the screw head to resist vibrations and won’t snag objects. It also offers greater vibration resistance than split lock washers. Metric washers meet DIN 6767 specifications. AFT offers steel and stainless steel washers with black oxide, zinc and plain finish options.
