Frequently asked questions

What is the 3/8 inch BSF lock nut used for?

The 3/8 inch BSF lock nut secures propshaft and drivetrain fasteners on Land Rover Series and Defender models, holding a joint tight against the vibration these vehicles generate. Its locking action resists loosening on the propshaft and driving member assemblies.

How many lock nuts are typically needed for a propshaft job?

Propshaft flanges typically use four bolts and nuts per joint, so a full flange usually needs four. These lock nuts are sold individually, so order the quantity your specific joint requires.

Can the 3/8 inch BSF lock nut be reused, or does it need replacing?

Lock nuts are typically single-use. The locking feature loses effectiveness once the nut has been torqued and removed, so fit new nuts whenever you disturb a propshaft or driving member joint on a Series or Defender.

Which Land Rover models does the 3/8 inch BSF lock nut fit?

This 3/8 inch BSF lock nut fits Land Rover Series 1, Series 2 and 3, and the Defender up to 2016. The BSF thread suits the imperial fasteners used across these drivetrain assemblies, so confirm your fastener thread before ordering.
