คุณลักษณะ

• This is a nut with pre-belling torque effect on general hex nuts and flange nuts fastened only by axial force.
• Even if the nut is in the middle position of the bolt, the anti-loosening effect is exerted.
• Even if you remove it once, you can use it again about 2~5 times.
• Can be used as is for the currently used portals.
• Compared to general use (hex nut + flat washer), one three-lock nut is fine, so workability is improved.
