$10.00

FORDIENUTA10M-10-40

Forster’s Lock Nut for Micrometer Seating Top is a small part that makes a big difference to your reloading setup. Purpose-built for Ultra Micrometer seater dies in .243 calibre and smaller, it locks your micrometer top down solid so your seating depth doesn’t walk under recoil, vibration, or long loading sessions. Set it once, snug the nut, and your settings stay put. Machined to Forster’s usual tight tolerances, this lock nut gives you repeatable, confidence-inspiring adjustments when you’re chasing tiny groups or consistent hunting ammo. It’s a clean, no-fuss upgrade for anyone running Forster Ultra seaters who wants rock-steady, repeatable seating depth without mucking around.

Key Features

Precision lock nut designed specifically for Forster Ultra Micrometer Seater Dies, ensuring secure retention of the micrometer seating top.
Fine 10-40 thread (DIENUTA10M-10-40) matches the original Forster specification, maintaining exact alignment and repeatable seating depth adjustments.
Purpose-built replacement part helps restore worn or damaged lock nuts, extending the service life of your existing Forster micrometer seater.
Compatible with small-calibre Ultra Seater bodies (243 and smaller), so you can keep multiple die setups correctly configured.
Machined to Forster’s tight tolerances to minimise play in the adjustment stack, supporting consistent, accurate cartridge assembly.
Simple, tool-friendly design allows quick installation or replacement, reducing downtime at the bench.
Genuine Forster factory spare ensures full compatibility and preserves the feel and function of the original die system.
