Business

Screw-First Deck Upgrades

Offer a service converting aging deck connections from nails/lag bolts to modern structural screws for improved safety and longevity. Use auger bits to prep pilot holes and drive long screws quickly in Timber Screw mode. Price per ledger, joist-bay, or stair run; market as a safety and maintenance upgrade with before/after torque checks.


Rapid Bore Service for Trades

Provide an on-call hole-boring service to electricians and plumbers: fast, clean bores through studs/joists with 7/16 in. hex-shank ship augers and self-feed bits. Charge per hole or per linear foot, offer same-day rough-in support, and bundle with optional firestop marking and clean-up to save GCs schedule time.


Pergola and Shade Structure Installs

Design-build pergolas, carports, and shade frames using structural screws to reduce hardware costs and speed inspections. The lift ring and compact tool simplify overhead fastening. Sell tiered packages (standard, premium hardwood, integrated lighting) and upsell seasonal maintenance/tightening.


Playset/Shed Assembly and Anchoring

Assemble heavy wooden playsets and small sheds with robust screw fastening for families and HOAs. Pre-drill and anchor into posts or concrete with appropriate adapters. Offer flat-rate assembly with add-ons for ground anchors, safety checks, and annual re-tightening service.


Ranch and Fence Fastening Mobile Crew

Serve farms and large lots with on-site repairs: gate hardware, fence rails, barn bracing, and equipment racks. The cordless, high-torque wrench drives big lags in remote areas without power. Charge a call-out fee plus per-fastener/footage, and schedule route days to maximize coverage.

Lag-Joined Pergola

Build a backyard pergola from 6x6 posts and 2x10 beams using structural timber screws instead of traditional through-bolts. Use 7/16 in. hex-shank ship auger bits for pilot holes and quickly swap to a 7/16 in. socket adapter to drive long screws in Timber Screw mode. The lift ring helps when positioning and fastening overhead beams; the LED aids alignment in shaded patios.


Treehouse Platform

Create an 8x8 treehouse platform anchored to posts or a tree-friendly bracket system. Bore clean pilot holes with 7/16 in. augers through thick lumber and drive 10–12 in. structural screws with high torque. The compact length and belt hook make ladder work safer, and the LED helps sight screws in dappled canopy light.


Reclaimed Timber Garden Beds

Assemble raised beds from reclaimed ties or 6x6 timbers. Pre-drill drainage and stake holes with large augers, then use a 7/16 in. socket adapter to sink long lags that won’t back out. Timber Screw mode speeds assembly, and the variable trigger lets you snug corners without splitting weathered wood.


Live-Edge Bench with Exposed Fasteners

Build a rustic bench using a live-edge slab and chunky 4x4 legs. Use self-feed or auger bits (7/16 in. hex shank) to create through-holes and shallow counterbores, then drive washer-head structural screws for an industrial look. The tool’s compact size helps in tight joinery spaces under the slab.


Backyard Climbing Wall

Frame and anchor a small outdoor bouldering wall. Drill clean holes for carriage bolts and anchor hardware, then secure the ledger and diagonal bracing with long timber screws. The lift ring assists when aligning panels overhead; switch speeds to avoid overdriving near panel edges.
