Top Plate Screw 1234170 - No 8 X 9/16 Inch (Short) Autotrol 255, 263, 268, 298, 367, 368 Valves

This is the genuine No.8 x 9/16 inch (short) top plate screw, part number 1234170, used to secure the top plate on Autotrol 255, 263, 268, 298, 367 and 368 valves. WrekinWater stocks it individually so you can replace a lost or stripped screw without buying a full fixing kit you don't need. It's a small part, but the correct length matters for a top plate that sits flush and seals properly.

Why you might need this

• A screw has been lost during a service or valve strip-down.
• You've stripped the head or thread on the original screw removing the top plate.
• You're missing hardware after buying a used or reconditioned valve.
• You want a spare on hand before starting a valve service.

The top plate screws hold the cover securely onto the valve body, keeping internal components correctly positioned and the assembly properly closed. Using the wrong length can either leave the plate not fully seated, or bind against internal parts if it's too long for this particular valve body. The short No.8 x 9/16 inch size is specific to these Autotrol models, so matching it exactly avoids either problem.

WrekinWater is a family run company based in Bettisfield, Shropshire, with more than 50,000 customers served over 15 years and an "Excellent" rating on Trustpilot. We stock genuine Autotrol parts down to the smallest fixings, so you can complete a repair properly rather than improvising with the wrong hardware.

How to fit it

1. Isolate the water supply and relieve pressure before opening the valve.
2. Remove any remaining old screws and lift away the top plate.
3. Position the new No.8 x 9/16in screw in the correct mounting hole.
4. Tighten by hand first, then snug with a screwdriver without overtightening into the plastic.
5. Repeat for any other screws being replaced at the same time.
6. Restore the water supply and check the top plate sits flush with no leaks.
