Drive Conversion
Both Directions In One Two-Piece Set
Choose the increaser for a 1/2-inch tool and 3/4-inch socket, or the reducer for a 3/4-inch tool and 1/2-inch socket. The pair contains two different fixed-direction adapters.
1/2" & 3/4" Impact Socket Adapter, 2-Piece Set | 1/2" ~ 3/4" Reducer and Increaser (LX-403)
Sale price
$25.97
Regular price
$29.97
Overview
LX-403 supplies two different impact adapters: a 1/2-inch female to 3/4-inch male increaser and a 3/4-inch female to 1/2-inch male reducer. This pair covers either drive mismatch, with chrome-molybdenum construction and detent retention for compatible tools and sockets.
Key Advantages
Impact Construction
Chrome-Molybdenum Steel For Impact Work
The set has chrome-molybdenum steel construction as fully impact rated, with manganese phosphate coating. Select matching impact-rated components and verify application limits.
In The Box
Adapters For The Listed Conversion
The package lists one 1/2-to-3/4-inch increaser, one 3/4-to-1/2-inch reducer and an organizing tray. Tools, sockets and a verified pin-and-ring kit are not listed contents.
Match the drive at both ends
The female end fits the tool anvil; the male end fits the socket drive recess. Socket drive size is separate from the fastener opening.
| Tool and socket | Works | What to check |
|---|---|---|
| 1/2-inch tool, 3/4-inch socket | With supplied increaser | Choose the 1/2-inch female to 3/4-inch male adapter. |
| 3/4-inch tool, 1/2-inch socket | With supplied reducer | Choose the 3/4-inch female to 1/2-inch male adapter. |
| 1/4-inch hex drill chuck | No direct square-drive connection | A hex chuck and square-drive anvil are different connections; no direct-fit promise is established. |
| Other square-drive sizes | No listed direct conversion | This product lists 1/2-inch and 3/4-inch connections. |
| Impact-rated sockets and matching anvils | Within component limits | Confirm retention, drive fit and limits for every component. |
| Pin and O-ring retention systems | Tool-specific verification needed | Check retention provisions; exact pin dimensions and compatibility are not specified. |

Questions
What are the two directions supplied in LX-403?
The pair combines a 1/2-inch female to 3/4-inch male increaser with a 3/4-inch female to 1/2-inch male reducer. Select one adapter according to the actual drive mismatch.
Which adapter do I choose for a 3/4-inch wrench and smaller-drive socket?
Choose the reducer marked 3/4 input and 1/2 output when the socket has a 1/2-inch drive recess. The other adapter in the pair serves a different input direction.
What is supplied for a 1/2-inch wrench driving a 3/4-inch socket?
Use the included increaser with its 1/2-inch female recess on the tool and 3/4-inch male square in the socket. Keep the unused reverse-direction adapter separate.
Can either adapter be flipped to do both conversions?
Each member has a fixed female recess and male projection. Two different adapters provide the two directions; turning one around does not exchange its square sizes.
Does LX-403 connect to a quick-change hex drill system by itself?
Neither included adapter is listed with a 1/4-inch hex shank. Both are square-drive conversions between 1/2 and 3/4 inch, so verify a compatible tool anvil.
Does the two-piece set include a fastener socket?
It supplies drive adapters rather than sockets that fit bolt or nut heads. Select the correctly sized impact socket separately for the fastener opening.
Are both pieces described as chrome-molybdenum impact adapters?
The design uses the set as chrome-molybdenum steel and fully impact rated. It does not give separate measured torque ceilings for the reducer and increaser.
Why are two different body sizes shown in the main image?
The pair contains two opposite square-drive conversions, rather than identical copies. Check the 1/2-to-3/4 and 3/4-to-1/2 markings when selecting from the pair.
Do the pair's detent balls lock every socket shape?
A spring-loaded ball retains a matched drive recess. Verify actual engagement for each socket; no all-socket retention test or compatibility chart is specified.
Does having both directions increase the load rating?
Set quantity does not establish higher load capacity. Choose one appropriate adapter and follow the limits of that tool/socket assembly; no added torque multiplier is documented.
Does the phosphate finish differ between the two adapters?
Both adapters have manganese phosphate corrosion protection. No separate coating performance or exposure rating is specified for either member.
Can I verify a retention pin diameter for both pieces?
No required pin diameter or ring dimensions are specified for the retention provisions. Confirm hardware fit separately rather than copying a pin from another tool.
How does LX-403 differ from buying LX-401 alone?
LX-401 is the one-way 1/2-to-3/4 increaser. LX-403 adds the separate 3/4-to-1/2 reducer, giving two adapters for workshops that need both directions.
Is LX-403 a multipack of the same reducer?
No. The listed base set contains one increaser and one reducer, with opposite female/male sizes. Its two-piece count refers to those different adapters.
Do the pictured pins and O-rings come in the two-piece package?
The set contains the two adapters; pin-and-ring supply is not confirmed. Check included retention hardware before planning an application that requires it.
Is an organizing tray mentioned for this pair?
The set includes a convenient tray. A hinged transport case or impact wrench is not confirmed as included.
Can I assume both pieces fit every high-torque driver?
Check the female drive size, retention and tool documentation for whichever member you use. Drive size alone does not confirm anvil fit or permissible load.
What warranty rules apply to the two-piece SKU?
Lifetime coverage when you register online within 90 days of purchase; 12 months standard without registration. Commercial use is covered for 12 months and cannot be extended; industrial use is not covered. Coverage is for defects in material and workmanship, excluding normal wear and tear, misuse, modification and non-original parts.
What should I check before the first use?
Check the marked drive sizes, complete seating and retention at both ends. Verify that all components suit the chosen tool and job.
Can I keep using an adapter with a cracked or rounded drive?
Stop using the damaged adapter and contact Lexivon for assessment. No approved home repair is specified.
What if the detent ball does not retain my socket?
Stop and check that the socket drive matches and seats correctly. If the retention feature is damaged or still does not engage, contact Lexivon before continuing.
Should I force an adapter that will not seat on the anvil?
No. Check drive size, retention design and condition before applying force. A generic quick-fit claim does not verify an incompatible or damaged connection.
Does normal wear qualify for automatic warranty replacement?
No. Warranty covers defects in material and workmanship and excludes normal wear and tear, misuse, modification and non-original parts. Lexivon decides the resolution after assessment.
Does heavy-duty truck use guarantee industrial warranty coverage?
No. Industrial use is excluded. Commercial use is covered for 12 months and cannot be extended, including heavy-duty applications.
