Type BK is particularly recommended when it is not possible to precisely determine the flange thickness or when the flange thickness varies within a structure.

Ideal for bridging slotted holes and for application at the open end of a C rail owing to wide rear section of clip.

The clips for screws Ø M8, M10 and M12 have an additional "nib" that fits into the opening of a C rail. This prevents the clip twisting on assembly.

Type BK features a flat surface, so that a nut or head of a bolt can be fully tightened.

Recommended tensile load

Values apply to a clamped connection (4 bolts), with loading in direction of screw axis.

Recommended transverse load

Values apply to a clamped connection (4 bolts) loaded at a right angle to the screw axis.
