Performance FH Hex Socket Screw 2.6x6mm

This countersunk FH hex socket screw is intended for use as an input shaft replacement in RC models. The YOKSD303S fits MR-4TCSD gear trains and carries a lock-processed thread finish to reduce the chance of screws backing out during spirited driving. Replace worn fasteners with these to maintain reliable clamp under load without disturbing shaft setting.

Fitment advice: check head seating and thread engagement before full torque, avoid over-tightening to protect the fine thread form, and re-check after a brief run. Supplied as a multi-piece pack so you can address common service needs trackside.

Packing includes

  • Countersunk FH hex socket screw 2.6x6mm - 6 pcs

Will these screws stay tight during aggressive driving?

The lock-processed thread increases resistance to vibration and shock, making these screws less likely to loosen during aggressive use, though periodic checks are still recommended.

Can these affect drivetrain feel or tuning?

Properly tightened and seated screws do not change drivetrain geometry; they simply maintain consistent clamp, which helps keep handling predictable between runs.

Are these convenient for trackside repairs?

Yes, the six-piece pack provides spare fasteners for common input shaft repairs, making quick replacements straightforward during meetups or practice sessions.
