ANTI-LOOSE WASHER

ANTl-LOOSE washer is composed of two parts. When the bolt is pre-tightened, the large tooth surface between the two parts is wedged to engage, thereby achieving the self-locking function.

ANTI-LOOSE Washer is designed with the big tooth bevel angle "α" greater than the thread lead angle "β". In this way, the two washers become staggered when the bot loosens due to the greater distance in lift distance than the thread lift distance of washer. This expansion behavior in the axial direction in return leads to an increase in clamping force, enabling an effective lock the device under conditions of vibration, stress changes, temperature fluctuations, and other states.

2.ANTI-LOOSE Washer specific Advantages

(1) The entire series of products ensures greater loosening torque than the tightening torque, and the long-term clamping force does not degrade significantly under impact, vibration and variable load, thus achieving effective long-term loosening prevention.

(2) The whole series of products can be bent more than 10 degrees to achieve excellent balance between hardness and ductility, without potential safety hazards of fragmentation in use.

(3) The ANTI-LOOSE stainless steel washer, featuring unique HLC4 technology, represents the leading solution worldwide for addressing the contradiction between hardening and corrosion of stainless steel.

(4) The ANTI-LOOSE alloy steel washer, utilising unique alloy catalytic technology, effectively addresses the issue of surface coating detachment. It passes the salt spray test for more than 600 hours and meets the environmental requirements of ROHS

(5) The whole series of products have been widely used in China's national railway, urban rail transit, aerospace, construction machinery and automobiles.
