Lock Rite Washers

Lock Rite Washers

Introduction of Lock Rite Washers :

Lock Rite Washers are used along with Bolts and offer resistance to self loosening during vibration and fluctuating loads. These washers wedge each other and lock themselves utilizing tension leading to a secure bolted joint. Using Lock Rite washers ensures a long term vibration proof locking devices. Applications Automotive, railways, marine, power plants, thermal energy, wind energy, construction, mining, marine, agriculture, off road, earthmoving equipments, onshore and offshore projects, process industries, switch gears, machineries, high voltage motors etc.

Our Disc Springs are AUSTEMPERED. This method of heat treatment is particularly effective for springs, as it gives the maximum toughness and therefore considerable durability.
