M20 x 21.0mm DIN 93 Long Tab Washer | A2 Stainless Steel
Manufactured for manufacturing equipment and fabricated frames, this M20 DIN 93 Locking Tab Washer uses A2 Stainless Steel with a 1.00mm washer thickness and 18mm tab width. Its long tab creates a positive mechanical restraint that helps hold nuts, bolts or machine screws against rotational movement.
What Are DIN 93 Long Tab Washers?
Long Tab Washers provide a mechanical anti-loosening method rather than relying on friction alone. The washer sits beneath the threaded fastener while the extended tab engages with the surrounding assembly to obstruct unwanted turning caused by vibration, shock or applied torque.
Common Applications
- Industrial Machinery: Helps lock nuts or bolts in position on equipment exposed to vibration and repeated mechanical movement.
- Electrical Equipment: Secures compatible threaded fasteners in control panels, switchgear and equipment housings.
- Construction Assemblies: Provides a mechanical locking washer for compatible structural and fabricated metalwork connections.
- Marine Equipment: Provides an anti-rotation washer for suitable marine and coastal assemblies when the appropriate stainless steel grade is selected.
