Hello.?? We have several fairly new adjustable benches.?? The seat lifting
jack is mounted to the side of the leg and stretcher frame.?? The heads
of the screws that mount the jack to the frame keep getting sheared
off.?? First, I got the old screws out and replaced them but still
happened.?? I'd find the seat collapsed and the screw heads on the floor.
I thought maybe small lag bolts would be strong enough, but I wanted to
check here to see if anyone had a better idea.
Thanks.
Robert
