Ultralok Collars

Ultralok Collars

Half collars increase the grip range to that of the next longest pin. Maximum grip increases by .062” for 3/16” and 1/4” fasteners and .125” for 5/16” and 3/8” fasteners. Flanged collars are used for applications where the collar side hole may be oversized or slotted.

When using half low profile collars the ultimate strength ratings are reduced by 45%.
