Business

Mobile Brake Bleeding Pop-Up

Offer a quick-stop motorcycle and car brake-bleeding service at weekend meets and track days. The 8/9 mm wrench covers many bleeder sizes; pair it with a vacuum bleeder and a magnetic bottle. Price per wheel, upsell fluid and a post-service lever feel check. Fast, repeatable, and low-overhead.


M5 Field Fastener Rescue Kit

Sell a compact kit on Etsy/Amazon: the 8x9 wrench, assorted M5 stainless nuts/bolts/washers, blue threadlocker, and a mini ruler. Market it to cyclists, DIYers, and makers. Emphasize the wrench’s DirectTorque design to protect hardware. Include a branded 3D-printed wrench clip for easy storage.


RC Glow Plug Service Add-On

Partner with local RC tracks/shops to provide a pit-side glow plug check-and-replace service. Use the 8 mm end for quick swaps, include plug testing, fuel line inspection, and clutch nut checks where applicable. Sell a small upsell kit with spare plugs and a wrench holster.


Cafe Micro-Maintenance Rounds

Offer monthly preventative maintenance for small fasteners on cafe equipment: tightening brackets, clamps, and small fittings that commonly work loose. Bundle with descaling reminders. The polished chrome wrench wipes clean in food-service environments and the dual sizes reduce tool clutter on crowded counters.


One-Wrench Workshop Content Series

Create short-form videos demonstrating real-world fixes using only an 8x9 open-end (e.g., brake bleed demo, bike rack install, RC glow plug swap). Teach proper wrench technique, the 15° flip method, and avoiding rounding. Monetize via affiliate links for the wrench, fastener kits, and your downloadable checklists.

Brake Bleeder Buddy Kit

Build a compact brake-bleeding kit for motorcycles and cars. Pair the 8 mm/9 mm wrench with a clear silicone hose, a jar with a drilled cap, and a small magnet clip. The 8 mm and 9 mm sides fit many bleeder nipples; the 15° offset helps crack and tighten bleeders without knuckle-busting in tight wheel wells. Add a simple hanger and check valve to make a tidy, reusable kit.


Vintage Bike Tune-Up Roll

Sew a minimalist tool roll dedicated to on-the-road vintage bicycle fixes. Stock it with the 8x9 wrench (for common M5 nuts such as cable pinch bolts and rack/fender hardware), a small cable cutter, spare M5 nuts/bolts, and a mini lube vial. The dual-ended wrench saves space, the DirectTorque features protect older hardware, and the stamped markings make quick ID easy in low light.


Nitro RC Pit Caddy

Make a laser-cut or 3D-printed pit caddy for nitro RC cars that nests the 8x9 wrench alongside glow plugs, fuel line, and a small screwdriver. Many glow plugs use an 8 mm hex, and the 15° offset helps clear headers or cooling heads. Include foam cutouts, a magnetized parts tray, and a lanyard so the wrench is always at hand.


Scooter/Moped Side-Cover Service Kit

Assemble a glovebox-sized kit for common panel and clamp fasteners on scooters/mopeds. Pair the 8x9 wrench with spare M5 hardware, fuel line clamps, and a short length of hose. The polished finish cleans up easily after roadside fixes, and the dual sizes cover many small clamps and brackets without carrying a full set.


Espresso Steam-Wand Quick-Fix Pack

Put together a barista-friendly pouch for tightening small compression fittings and clamps often found around steam wands and drip trays. The 8 mm and 9 mm ends handle many small metric fasteners in tight cafe equipment cavities where the 15° offset gives extra swing. Add PTFE tape, food-safe lubricant, and spare M5 hardware.
