5MM Nut
$9.00 - $18.00
Designed to prevent your mouthpiece Backbore from coming unscrewed in the receiver, the Nut is available in .020" incremental lengths to reduce or completely fill External Visual Gap (EVG). This is the gap you see at the union of the mouthpiece Body and the Receiver. Measure your EVG with the Nut Measurement Tool, then order an extra Nut the same size as the largest tab to fit in the space between the Body and Receiver.
5MM Nut options: Trumpet, Cornet, Flugelhorn
The 5MM Nut locks the Backbore in place and fills the external space between the Body and Receiver. Two diameters to match various Body styles
Length options The 5MM Nut is available in every length variation. We do not offer exchanges on Nuts as you will very likely find that the Nut originally supplied with your 5MM Kit will fit receiver variations in the future. To order the correct size Nut to completely fill your external gap, measure the nut from the body and measure the space between the mouthpiece and receiver. Do not make any adjustments to this number. We will reduce the length by approximately .005" to allow for error and wear over time for a perfect fit. |
