Oglaend offer a wide range of nuts, bolts and fasteners. Our unique all metal anti-vibration flange nuts stay securely tightened without the need for washers, nylon nuts or thread locking compounds. The key to the anti-vibration system is advanced technology in the thread design, which restricts movement between the nut and bolt during vibration, thus preventing loosening. Installation time is reduced as the flange nuts are free running onto bolts with no resistance, and are then tightened with one hand and one tool.
