Description

During installation, the nose equipment of the placing tool slides over the collar and swages the collar into locking grooves on the fastener stem. Material from the collar flows into the grooves locking the stem in place and creating a virtually tamper proof joint. Additionally, as the nose piece moves futher along the collar, collar material flows toward the base of the collar and forms a flange on the surface of the application. This prevents tool contact and possible damage to the application and creates a load bearing surface, which absorbs the force of setting the fastener. Otherwise the setting force, or clamp load, might spread into the application and damage the material.

The Avbolt® fastener enlarges the wide range of Avdel® structural bolts by offering a high tensile and shear strength (normally only possible with non blind lockbolts) with the versatility of blind products. The Avbolt® fastener is ideal for areas with restricted access. It´s simple to use with fast, positive single sided installation requiring minimal operator skill. The locking feature creates a vibration resistant joint and prevents loosening stems. Ease of inspection for correct installation and excellent tamper resistance are further advantages.
