I had mentioned Harbor Freight a few months back when I purchased one of its mini toolboxes at a radio swap meet (https://luegra.design.blog/2026/02/21/buys-at-the-livonia-swap-meet/). However, I have never mentioned that the store is extremely useful for securing some tools to do basic stringed instrument repairs.
I joined the store’s Inside Track Club, which gets me unadvertised sales as well as additional discounts and occasional free stuff. While the store itself is geared more toward professional workers such as electricians, carpenters and auto mechanics, there are some items here that can prove priceless in the guitarist’s gigbag or on the luthier’s workbench.
Precision screwdrivers – try to use a regular screwdriver on those screws holding the tuning gears in place, and you will probably strip the head. The sets that I have purchased at the dollar stores are terrible to say the least. Harbor Freight’s Pittsburgh line of hand tools have a lifetime guarantee, and it has a few different sets of these screwdrivers for as low as $5.99.
Pliers/side cutters – the smaller-sized ones that are perfect for musicians. The small needle-nose pliers ($2.99) are great for getting in to tight spots as well as tightening an output jack nut or tuning gear nut when a small wrench won’t fit or isn’t available,. The side cutters ($2.99) are a must for cutting the cat whiskers on guitar strings.
Sandpaper – yes, you can get this just about anywhere, but not the selection that you can find at Harbor Freight. Most stores sell grit up to about 1200, but here you will find 2000 grit, which is great for final sanding on finishes.
Precision Files – while this set ($5.99) may still too wide for slots in nuts, they can still be good for getting into places that a larger files cannot, like tuning gear mounting holes and output jack holes.
Soft-face mallet – useful when you want to fit something into a tight hole and not leave scratches. This mallet ($7.99) has a rubber and plastic head for light tapping parts into place.
Ammo boxes – there are two sizes: .30 caliber ($5.99) and .50 caliber ($19.99). I use two for storign my guitar strings, and one serves as my traveling guitar repair kit, holding all the necessary tools that I may need if I have to handle a minor repair at a show for someone (it has happened).
Magnetic parts holder – this looks like a shiny metal ashtray ($4.99), but has a heavy magnet on the bottom. How many times have you taken the pickguard off of a Stratocaster and end up losing a screw or two when putting it back on? This holds those metal parts tight in the bowl until needed.
Rotary tool – Harbor carries a light-duty model ($9.99) that is a lot cheaper than a similar Dremel model, and will prove its worth when doing some small drilling/sanding/polishing jobs.
Mini toolbox – this item is perfect for keeping the small luthierie tools in one place. It usually goes for $19.99, but often go on sale for less.
Other items available are cable ties, shop towels, batteries in bulk, mini flashlights, and a lot of other stuff. Joining the Inside Track Club may be worth it at $30.00 for one year or $45.00 for two years. I use it to get plenty of other tools and accessories for home repairs plus it gets me some free stuff about once a month.
Chew on it and comment.
