Master Sets

These are the professional-grade kits for setting up a new shop, outfitting a service truck, or standardizing tooling across a maintenance crew. Every set here is built by Wright Tool in Barberton, Ohio: hot forged alloy steel, built to ASME B107-series standards, and covered by the manufacturer's Limited Lifetime Warranty. Buying one master set instead of piecing tools together gets every mechanic the same sockets, wrenches, and drive tools, which matters when a crew shares a truck or a tool room signs tools in and out.

Which size master set fits the job

TierTypical piece countWho it fits
Apprentice and starter sets50 to 100 piecesFirst-year mechanics, single-trade service calls
Intermediate sets200 to 260 piecesGeneral maintenance techs, one loaded service truck
Master maintenance sets260 to 370 piecesPlant maintenance rooms, aircraft and fleet shops
Mega master sets425 to 556 piecesFull shop or tool-crib standardization in one purchase

Fractional (SAE) sets cover 1/4", 3/8", 1/2", and 3/4" drives; metric master sets and add-on sets extend the same drives in millimeter sizes. If your fleet mixes domestic and imported equipment, pair a fractional master set with a metric add-on set instead of doubling up on drive tools.

What comes with a set

Sets arrive tools-only in fitted metal boxes, so they drop straight into an existing tool room. If you are outfitting from scratch, browse tool storage for chests and utility carts sized to hold a master set, and torque tools to round out an engine or structural bay. Individual sockets and ratchets and wrenches are also available open-stock for fill-ins, so a lost socket never sidelines the whole set.
