Product Description

Royal Enfield 570198/C is a genuine OEM tappet door screw, officially listed as a CSK socket head screw M5 x 0.8 x 12. This is the small countersunk Allen screw used at the tappet door / tappet cover area on many older Royal Enfield UCE and GT 535 models.

SOLD AS A SET OF 4 PCS 

This is the correct OEM replacement when the original tappet door screw is rounded, stripped, rusted, missing, or damaged during tappet cover removal, oil leak repair, or engine-side service. Buyers may search for it as tappet door screw, tappet cover screw, Allen tappet screw, M5 countersunk screw, or Royal Enfield tappet screw.

Before you buy: match 570198/C, confirm your fastening point is the tappet door / tappet cover screw position, and check the countersunk Allen head style before ordering.

FAQs

What is 570198/C exactly?

It is the genuine Royal Enfield tappet door screw, officially a CSK socket head screw M5 x 0.8 x 12.

Is 570198/C used on the tappet door?

Yes. Multiple crankcase-right parts diagrams place 570198/C directly with the tappet door assembly.

Is 570198/B the old number for this screw?

Yes. Public parts pages show 570198/B replaced by 570198/C.

Will this fit Classic 350 and Classic 500?

Yes. Surfaced dealer fitment explicitly includes Classic 350 and Classic 500 EFI.

Can I use any M5 countersunk screw from a hardware shop?

Not ideal. OEM is safer for correct head shape, finish, and application match at the tappet door fastening point.

How do I avoid ordering the wrong screw?

Match 570198/C, confirm you need the tappet door / tappet cover screw, and check the countersunk Allen head style before ordering.
