Grover F-Style 309 Mandolin Tuning Machines

About This Item

Grover F-style mandolin tuners are available in two different gear configurations, with engraved die-cast baseplates and 18:1 gear ratio.

Standard 29/32" (23mm) string post spacing.
11/32"-diameter (8.73mm) pegholes required.

Each set includes:
• Pair of 4-left, 4-right tuning machines
• Removable pearloid plastic knobs
• Press-fit peghead bushings
• Mounting screws

Available in two different gear configurations:
#5675 with worm gear under string post (turn the the knob counterclockwise to tighten the string)
#5674 with worm gear over string post (turn the knob clockwise to tighten the string)
Important: These two styles may not be interchangeable on the same peghead. See Specs before ordering.

Installation Tips

Peghole spacing: Plate-mounted tuners can't work efficiently if the pegholes are improperly drilled. Our Mandolin Peghead Drill Jig ensures precise 29/32" spacing for accurate alignment for these tuning machines.

Bushings: We recommend the Standard Peghole Reamer to cut smooth, perfectly round holes.

Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1711 Depth-stop Drill Bit (No.50 bit) for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.

Great tuners!

By

Verified Buyer


The old tuners on my mandolin were starting to slip. These tuners are very smooth and were easy to install. I have Grover tuners on my Dobro as well and they always look good and are very smooth.

great tuners - fit well on eastman md-415 mandolin

By

Verified Buyer


great tuners - 3 inner screws line up perfectly on the Eastman md-415 mandolin outer 2 do not line up - Eastman makes great mandolins but their tuners are not so good - too tight - these work better to tune your instrument - highly recommended

New keys for my mandolin

By

Verified Buyer


I purchased a new set of Grover keys for my mandolin a few years back and they worked great but one late night at a campfire picking session I notice one of the G strings hard to turn next morning I seen I had lost a small screw out of the worm gear shaft. When I got home I called StewMac, explains my dilemma and asking if I could get a replacement screw to my surprise they said I had a full warenty and I was sent a new set. This is the kind of support that says so much about this company. Thank you so much!

I got these to replace the stock tuners on my Eastman 515. Much, much smoother and more precise and stable. Would heartily recommend.
