Four Adjacent Square Drive Conversions
Use the included 1/4-inch female to 3/8-inch male increaser. The female end fits the tool and the male end enters the socket.

LX-112 supplies four square-drive adapters and reducers for adjacent 1/4, 3/8 and 1/2-inch drive changes. It has female square inputs rather than hex shanks, making it a connection-size kit for matching square-drive tools to sockets.
Use the included 1/4-inch female to 3/8-inch male increaser. The female end fits the tool and the male end enters the socket.

Heat-treated chrome molybdenum alloy steel. Manganese phosphate treatment is listed for corrosion resistance. Confirm the operating load for your application.

Four conversions: 1/4-inch female to 3/8-inch male; 3/8-inch female to 1/4-inch male; 3/8-inch female to 1/2-inch male; 1/2-inch female to 3/8-inch male, with organizer tray.

Choose by connection size, socket opening, reach and working clearance.
| Job or attachment | Works | What to check |
|---|---|---|
| Listed drive connections | Yes, when sizes match | 1/4, 3/8 and 1/2-inch square-drive conversions. Confirm secure seating. |
| Automotive and maintenance work | Application dependent | Match the socket opening, working space and tool capacity to the fastener. |
| Other drive sizes | No assumed direct fit | Check the input and output drive separately before buying. |
| Unidentified vehicle or tool model | Not a verified fit guarantee | Confirm the required fastener size and actual tool connection. |
| Unspecified high-torque work | Operating limit needs confirmation | Ask Lexivon for the size-specific operating limit before high-load use. |
Use the included 1/4-inch female to 3/8-inch male increaser. The female end fits the tool and the male end enters the socket.
Select the 3/8-inch female to 1/4-inch male reducer. Its smaller output remains a separate connection to check for your intended load.
Select the 3/8-inch female to 1/2-inch male increaser. The female end attaches to the wrench and the male end goes into the socket; seat both connections securely.
The included 1/2-inch female to 3/8-inch male reducer provides that connection. Verify the socket seats on the smaller output and that the setup suits the load.
No direct 1/2-to-1/4 conversion is in LX-112's four-piece list. Do not mistake adjacent conversions for that missing single piece.
It is a 1/4-inch square recess, not a hex shank. A compatible hex-to-square adapter is a separate type of accessory.
Two pieces increase and two reduce adjacent square-drive sizes. Identify the female input and male output rather than relying only on an adapter's larger marking.
LX-112's four square-drive adapters and reducers use heat-treated chrome molybdenum alloy steel and impact-grade construction.
Keep the 1/2-inch input to 3/8-inch output reducer within the conservative 2,000 in-lb (about 167 ft-lb) value. Do not transfer it to the other three conversions; confirm their limits for your application.
No. The reducer changes the connection size; it does not establish a higher load capacity for your smaller socket. Confirm the LX-112 operating limit for your selected conversion and tool before high-torque work.
They can provide matching square-drive connections, but follow the wrench maker's accessory guidance. The reducer neither measures torque nor establishes the wrench's usable range.
No. A matching drive size does not make damaged retention safe. Stop using a connection that will not hold securely and contact Lexivon.
LX-112 supplies four square converters. LX-109 combines those four conversions with three 1/4-inch hex-shank socket adapters, giving seven components total.
LX-112 lists manganese phosphate treatment for corrosion resistance. Do not infer the black phosphate wording of another kit as this set's coating.
The through-hole is a documented retention feature. The included-item list does not confirm supplied pins or O-rings, so check your tool's requirements separately.
The listed working contents are four adapters/reducers. An organizer tray is described, but fastener sockets and long extension bars are not listed as supplied.
The organizer holds two increasers and two reducers with laser-marked sizes. Read both input and output markings before selecting a conversion.
Register LX-112 online within 90 days for lifetime defects coverage. Standard unregistered coverage is 12 months; commercial use remains limited to 12 months.
Identify the female recess for the tool and male square for the socket. Check both markings, particularly when choosing between the opposing 3/8 and 1/2-inch conversions.
Stop using that reducer and contact support. Do not continue just because its larger input still fits the tool or because another conversion in the set works.
Inspect the correct drive fit and contact Lexivon if the retaining ball will not hold securely. Changing adapter size does not repair a faulty retention feature.
Compare the kit with the four listed female-to-male conversions. Ask the seller or Lexivon about any duplicate or missing conversion before attempting the job.
Commercial use has 12 months coverage and cannot be extended. Industrial use is excluded; lifetime registration does not override those usage terms.
No. Coverage is for material and workmanship defects. Normal wear, misuse, modification and damage from non-original parts are excluded; Lexivon determines the resolution under its policy.
