Royal Enfield Self Tapping Torx Screw (T20) 4.0×10 White – DELTA PT – 148396/B (Often searched as 148396/C) – Genuine OEM

SOLD AS PACK OF 10 PCS 

Need the exact OEM screw your Royal Enfield uses on panels and assemblies? Royal Enfield 148396/B is a self-tapping Torx (T20) DELTA PT screw, size 4.0×10, white, used widely as an OE fastener where Royal Enfield fastens into plastics/thermoplastic parts and bodywork points that require a self-tapping thread. 

This is the correct choice when your original screws are missing, stripped, rusted, rounded, or replaced with incorrect “local” screws that damage plastic bosses or don’t seat properly—leading to rattles, cracked panels, and repeat loosening. DELTA PT-style screws are designed for reliable fastening into thermoplastics (better thread-forming behavior than random self-tappers).

Fitment note (returns control): Hardware part numbers can be used across many models and sub-assemblies. Royal Enfield doesn’t always publish an easy “model list” for generic fasteners—so order by part number + size/spec (4.0×10, Torx T20, white) to ensure correctness. The exact suffix /C is not verified publicly; the verified service part shown is 148396/B.

Compatibility Table 

Because this is a generic OEM fastener, trusted sources confirm the part identity/spec, but do not publish a reliable “model-year list”. Therefore compatibility is “order-by-part-number/spec”.

FAQs

1) Is 148396/B the same as “Torx self tapping screw”?
Yes. It’s listed as self-tapper / Torx (T20) / DELTA PT / 4.0×10 / white. 

2) Where is this screw used?
It’s a common OEM fastener used in multiple assemblies. Best practice is to match by part number or old screw spec, because RE may reuse the same fastener across models. 

3) What tool do I need?
A Torx T20 driver/bit. 

4) Why DELTA PT matters?
DELTA PT screws are designed for reliable direct assembly into thermoplastics and help reduce cracking/loosening versus random screws.

5) I searched 148396/C—will 148396/B work?
I can’t claim that without proof. If you share a photo of the box label / old invoice showing “148396/C”, I’ll confirm whether it supersedes to /B.
