This Quick-Release Failsafe Rod Nut replaces the original Wing Nut on Dillon Powder Measures. The Quick-Release feature lets you loosen it quickly when performing caliber changes.

Better than a Button
The Quick-Release Failsafe Rod Nut utilizes a double-ended collet with a total of eight fingers that grip the Failsafe Rod threads a full 360 degrees. So, the adjustment will not loosen after multiple cycles of the powder measure … unlike button-release nuts which engage the threads barely 180 degrees on just one side.

Large 3/4″ Diameter with Knurling for Easy Adjustment
Double-Ended Eight-Finger Collet Grips Failsafe Rod Securely
Releases with Just 1 Full Turn of Cap
Made from Durable Delrin®

Primer Follower Rod
Low Powder Sensor Rod

Primer Follower Rod
Fits the Primer Follower Rod … allowing you to adjust the level at which the Primer Early Warning System triggers. This can be used to give you a "Heads Up" that it is time to check your powder level. The Quick-Release Nut will grip the Primer Follower Rod at any level you desire, won't scar the plastic rod, and only adds 0.16oz (less than the weight of a .45 ACP case).

Low Powder Sensor
Fits the Low Powder Sensor follower rod … allowing you to adjust the powder level at which the Low Powder Sensor triggers. This can be handy for certain gunpowders that tend to meter less accurately when the powder level gets low. The Quick-Release Nut will grip the Follower Rod at any level you desire.

The stop nut that stays in placeWas really a little skeptical on this but after 7000 rounds it has not moved at all. I marked it on installation to see it lived up to the claims and it does. Just did a change over and removal and reset is quickand easy comaped to the wing nut. A little pricey but a set it and forget it item makes it's value go a long way in my opinion. Good value and recommended. Written by Dermako on Fri 27 Jan 2023 5:28:43 PM GMT
Quick Release Failsafe Rod NutThis is one of the best upgrades I’ve come across for the Dillon reloading press. This quick release nut should come with all Dillon presses. It’s easy and quick to install and remove.

It’s one of those parts which seems negligible, until you use it. I have them installed on all three of my Dillon presses.

Not just another wing nutI just installed the quick release fail safe rod nut item #T1753 on my Dillon 650. The design is great for aiding in quick caliber changes. It is very quick and easy to adjust.

It’s another innovative upgrade for your Dillon press.
