What it is

The Andrews Z291 is a socket head cap screw (SHCS) with a 10-32 thread and a 3/4 inch length. It is used across Andrews Water Heaters Ecoflo appliances and associated hot water spares. The hex-socket head allows the screw to be driven with an Allen key where access is restricted.

Signs this part needs replacing

  • Rounded or stripped hex socket, so the Allen key no longer grips
  • Corrosion or rust on the head or threads
  • Crossed or damaged threads
  • Screw missing from the assembly it secures
  • Screw will not hold torque and keeps working loose

Before you order

  • Confirm the thread size (10-32) and length (3/4 inch) match the fastener being replaced
  • Check your appliance model against the manufacturer's parts list
  • Inspect the mating thread in the component for damage before fitting a new screw
