3MSJ-3463Hook and Loop Fasteners

The SJ-3463 is a reclosable fastener manufactured by 3M. The SJ-3463 features Dual Lock technology, which utilizes mushroom-shaped stems that interlock with other surfaces also using the same head. This means that Dual Lock systems, unlike Velcro, only use a single contact surface type (i.e., both surfaces use the same material to form a bond). The shape of the SJ-3463 is circular with a hole in the middle for use with screws that require countersinking. The dimensions of the SJ-3463 are a 20.6-mm diameter with a 4.1-mm internal diameter hole.
