Drive Conversion
Reduce A 3/4-Inch Drive To 1/2
Connect your 3/4-inch tool to a 1/2-inch drive socket with the fixed-direction reducer. It changes socket fit without limiting torque, so verify the smaller-drive component's rating.
3/4-Inch Impact Socket Adapter, 3/4" Female x 1/2" Male Reducer | Chrome-Molybdenum alloy steel = Fully Impact Rated (LX-402)

Overview
LX-402 reduces a 3/4-inch tool drive to a 1/2-inch socket drive through one impact-rated adapter. Its chrome-molybdenum body and detent retention provide the documented conversion, while the tool and smaller-drive socket still require appropriate application limits.
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
One 3/4-inch female to 1/2-inch male reducer. Tools, sockets and a verified pin-and-ring kit are not listed adapter 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 |
|---|---|---|
| 3/4-inch tool, 1/2-inch socket | Matching conversion | Female 3/4-inch input, male 1/2-inch output. |
| 1/2-inch tool, 3/4-inch socket | Wrong direction for this adapter | Choose the opposite drive conversion. |
| 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 connection does the LX-402 reducer make?
LX-402 accepts a 3/4-inch tool anvil and presents a smaller 1/2-inch male square for the socket. Check those two drive connections independently of the nut opening.
Can my 3/4-inch wrench drive an existing 1/2-inch socket with it?
The female 3/4-inch input and male 1/2-inch output are listed for that pairing. A drive match alone does not prove that the smaller socket or adapter can accept every load from the larger wrench.
Will this reducer lower torque to protect the 1/2-inch socket?
No torque-limiting feature is documented. The adapter changes connection size, so the tool setting and component ratings still determine the permissible work.
Can I use LX-402 in the opposite direction on a 1/2-inch wrench?
It does not reverse its fixed input and output. A 1/2-inch wrench feeding a 3/4-inch socket requires the LX-401 increaser rather than this 3/4-to-1/2 reducer.
Is the 1/2-inch male end the same as a 1/2-inch nut opening?
The male square enters the socket's drive recess. The socket's nut opening can be a different size entirely; select that opening for the actual fastener.
Does truck wheel use establish a fit or load guarantee?
Verify the 3/4-inch tool, 1/2-inch impact socket and job requirements before wheel work. Drive size alone does not confirm truck fit or a permissible torque.
How is the small male drive retained in the socket?
The design provides a spring-loaded detent ball, visible on the 1/2-inch output. Check proper engagement in your socket before loading the reducer.
What does fully impact rated mean for LX-402 here?
The chrome-molybdenum reducer is impact rated, with a standard torque value of 700 Nm. That value is not a documented tested maximum; follow the limits of the tool, socket and retention hardware.
Does a broken 1/2-inch end prove the wrench was too powerful?
A broken reducer needs Lexivon assessment. Confirm application limits rather than diagnosing overload from connection size alone.
Can I connect LX-402 to a hex bit holder without another part?
A hex bit holder is not its documented 3/4-inch female square input. No direct drill-hex attachment is established for this reducer.
Which body marking should I check before attaching it?
Check the reducer markings for the 3/4-inch input and 1/2-inch output, then compare the recess and projection with the tool and socket. Laser-etched sizes help identify the direction.
Is LX-402 sold as a chrome-plated socket?
It is a chrome-molybdenum adapter with manganese phosphate coating. Chrome in the alloy name does not establish a polished chrome-plated socket finish.
When would I choose LX-401 instead of LX-402?
Choose LX-401 when the tool is 1/2-inch drive and the socket is 3/4-inch drive. LX-402 serves the reverse combination, with a 3/4-inch tool and 1/2-inch socket.
Does the single reducer also include an increaser?
LX-402 lists one reducer. The separate LX-403 set lists both conversion directions; do not assume the second adapter comes with this individual SKU.
Are pins supplied for locking the reducer on every anvil?
A through-hole and retention illustration do not establish an included pin assortment or universal pin diameter. Confirm the hardware and anvil compatibility for the 3/4-inch input separately.
Can I use ordinary non-impact sockets because the adapter is impact rated?
The adapter's claim does not certify a socket added to it. For impact work, choose a socket and retention arrangement whose own documented rating suits that application.
Can a replacement be guaranteed to last at any tool setting?
No durability guarantee follows from drive size alone. If a replacement fractures, review the job and component limits with Lexivon before continuing.
What are LX-402's registration and use conditions?
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.
