Nickel M9 Metric Pedal/Amp/Guitar 1/4" Input Output Jack Replacement Nut Set - 100 Pack - Made In Japan - High Quality New Part

Here for sale we have a set of 100 high quality Made In Japan nickel M9 metric standard 1/4" Input/Output jack nuts. This metric standard is used on most pedals, amps, guitars, and other audio electronics made in Europe and Asia, such as Boss/Roland, Ibanez, and many other brands. If you've been looking for a metric standard replacement for a lost or broken jack nut for your input jack you have finally found it! These larger packs are great for people with large gear collections, music stores, or people who repair gear and want to keep a stock of commonly needed parts.

These jack nuts thread onto the input/output jack on the outside of your gear to help secure the jack in place so it doesn't wiggle around. This set includes 100 nickel plated high quality steel nuts.

These premium high quality Made In Japan nuts are manufactured from high grade steel with a fine nickel finish, which helps prevent corrosion as well as providing a nice decorative look which will patina with age. Unlike some cheap replacement nuts, these will not rust/corrode quickly, will not have a finish that flakes off after minimal use, and will not have issues threading onto the jack. These nuts are the correct metric threading (there is more than one standard size for jack nuts), and correct thickness for use on these jacks, and are made to last for a lifetime!

Whether you just want to get a workhorse piece of equipment back to working properly, or want to increase the resale value on a broken/aged piece of gear by getting it back in tip top shape, if you have gear that uses the metric jack nut size and want the jack to be securely held in place again these are the ones to get!

NOTES ON FITMENT: As mentioned above there is a 2nd standard size for jack nuts. Many pedals, guitars, and amps, especially those made in Europe, Japan, Taiwan, Korea, or other parts of Asia use the standard that these nuts use. Many American made pedals, guitars, and amps, use the other American standard. These will not fit MXR, Gibson USA, Fender USA, etc, although they will fit some gear made overseas by these companies on brands owned by them such as some Epiphone, Squire, etc products. There is also a newer style of jack that doesn't use an exposed jack with threads and an external nut like the traditional style, but is recessed; these will not work on that style. Newer MXR pedals and some other brands use these.

If your jack looks like the traditional jack style found on Boss pedals, and is manufactured in Asia or Europe there are good odds these will work, but we cannot guarantee fitment on anything based solely on brand name or place of manufacture. You need to verify if these nuts will work on your equipment yourself. The easiest way to see if you are not sure is to take a nut from a Boss pedal and swap it onto the pedal/guitar/amp you're not sure about. If it threads on correctly then it uses this style, if it doesn't it is probably the American standard. Feel free to message us with any questions and we will try to help if we can!
