BeamClamp M20-BA-2

The types BA and BB are commonly used in pairs to clamp two steel sections together. The type BA has a recessed top to grip the head of a grade 8.8 setscrew or bolt, this allows a nut and washer to be tightened down on to the flat top of the BB using one tool only. Both clamps are available with three tail lengths 1,2 or 3 (dim E), this should be as near to the thickness of steel it is clamping on or slightly less if an exact match is not possible.
