This listing is for the genuine Royal Enfield 574108/B – HEX SOC HEAD SCREW M6 × 20. In the official Himalayan 410 Euro-4 parts pages it appears in multiple groups (crankcase LH, starter system, and related engine covers) exactly as “574108B – hex socket head screw M6x20”, so we can confirm it for Himalayan 410 Euro 4 / BS4 without guesswork. 

SOLD AS FULL PACKET

This is the OE M6 flange-class fastener RE uses where they need a socket/Allen head and 20 mm length — typically on alloy engine covers and starter/case brackets. Using the correct OE screw matters because RE picks the length to engage the full thread but not bottom out in the crankcase. If a customer replaces it with a too-long hardware-shop bolt, the case can crack; too short and it won’t clamp. Keep a few of these on your product page as “OEM replacement case screws” for Himalayan owners doing engine/case work.

FAQs

Q1. What size is this exactly?
It’s M6 × 20 mm, socket (Allen) head, 1.0 pitch. That’s what the Himalayan Euro-4 parts page shows. 

Q2. Can I use a local M6 bolt instead?
Only if it’s the same length and head style. RE chose 20 mm for that hole — too long can bottom in the case, too short can strip. OEM is the safe option.

Q3. How many do I need?
Your microfiche will show the quantity — some case groups need 3–6 of these. Buy that exact number.

Q4. Will it fit BS6 Himalayan / Scram 411?
Check part number before purchase. 

Q5. Is this stainless?
No, it’s the standard OE plated/finished fastener RE supplies; match it to the rest of the engine screws.
