Magnetic Retention
Six-Inch Reach For 5/8-Inch Plugs
Choose the 6-inch assembly when that reach and clearance fit the job. A magnetic core helps retain a matching 5/8-inch plug; check engagement before turning.

Overview
The 6-inch LX-121 gives a 5/8-inch magnetic spark plug socket a swivel joint and attached reach for confined access. Its 3/8-inch drive accepts a matching hand tool; compare the six-inch assembly with the plug well and space above it.
Key Advantages
Swivel Access
Position The Socket In Tight Spaces
The swivel joint and 6-inch overall reach help position the socket around confined access. Check clearance through the full path before turning.
In The Box
One Socket With Attached Reach
One 6-inch swivel magnetic spark plug socket is shown. It connects to a 3/8-inch drive hand tool supplied separately; spark plugs and a ratchet are not listed contents.
Will it reach your spark plugs?
Check plug hex size, plug-well clearance and working length. Socket opening, square drive and total length describe different dimensions.
| Plug or tool | Works | What to check |
|---|---|---|
| 5/8-inch hex spark plugs | With sufficient clearance | Check engagement depth and clearance along the entire socket and shaft. |
| 3/8-inch square-drive hand tools | Direct drive match | Use the correct fastening procedure and tool for the spark plug. |
| 1/2-inch drive ratchets | No direct drive match | Socket has a 3/8-inch drive; do not confuse it with the 5/8-inch plug opening. |
| 14 mm or 13/16-inch plug hex | No matching opening | Choose a socket with the specified opening instead. |
| Narrow or obstructed plug wells | Application dependent | Check socket outer clearance and the 6-inch total length; thin-wall marketing is not a universal fit guarantee. |
| Power impact tools | Not established | For manual torque tools; no impact rating is specified. |

Questions
When should I choose the 6-inch LX-121?
Choose its 6-inch total reach when that length can engage the plug while leaving room for your hand tool. LX-122 is 10 inches overall; more length is useful only if the working space accommodates it.
Does LX-121 fit a 5/8-inch spark plug?
Its six-point plug opening is marked 5/8 inch. Confirm that size on the actual plug, then verify full hex engagement before applying force.
Will the 6-inch length suit motorcycle plug access?
Motorcycle fit depends on the plug hex and space around the frame. Check the complete insertion path rather than assuming six inches is the right reach.
Will this short swivel reach every rear-bank automotive plug?
The joint can help position the socket, but the 6-inch assembly and surrounding parts still limit access. Confirm the particular engine layout and available working angle.
Can I connect a 3/8-inch torque wrench to LX-121?
The female drive accepts a matching 3/8-inch square tool. The product is described for manual torque tools; obtain the plug maker's torque and correct procedure separately.
Is six inches the shaft length before adding the socket?
Six inches is the listed length of the complete LX-121 assembly. Counting an extra socket length on top would overstate its documented reach.
How does the magnet differ from a rubber-insert socket?
LX-121 uses a magnetic core for retention. Buyers seeking to avoid a displaced rubber gasket can consider this design, but still need to check how their own plug seats and holds.
What if I need 14 mm rather than the marked 5/8 inch?
Select a socket whose opening matches the plug specification. The 5/8-inch opening is LX-121's fixed size; changing its length or drive tool does not convert it to 14 mm.
Does the thin wall extend along the full LX-121 assembly?
The socket is thin-walled, but no outer-diameter profile is specified. Confirm clearance along the full assembly, including any wider body sections.
Can I rely on an audible swivel angle or torque rating?
No numeric bend-angle or torque ceiling is provided for LX-121. Its 360-degree swivel claim identifies movement around the joint, without quantifying every working angle.
Does the magnet guarantee full-depth contact on every 5/8-inch plug?
Retention and engagement are separate checks. Confirm full seating on the plug hex and stop if the hex is only partly engaged.
Is LX-121's polished shaft equipped with a grip?
The shaft and socket have knurling alongside polished chrome plating. That grip feature does not establish a prescribed hand-tightening torque.
How do LX-121 and LX-122 differ in reach?
Both have a 5/8-inch opening and 3/8-inch drive. Choose LX-121 for the listed 6-inch overall assembly or LX-122 for 10 inches, after checking the plug well and room above it.
Is the 6-inch tool sold with loose universal-joint pieces?
LX-121 is a swivel socket-and-shaft assembly. Confirm separable-component capability before relying on loose extensions for your workflow.
Do I get a full socket set when I buy LX-121?
LX-121 contains a single 5/8-inch swivel magnetic socket. Other plug openings and the ratchet must be selected separately.
Are chrome vanadium and chrome plating the same specification?
For LX-121, chrome vanadium describes the listed steel alloy; chrome plating describes its polished finish. Neither supplies a numerical impact or torque rating.
Can the 6-inch socket remove plugs under impact power?
LX-121 is intended for manual torque tools; no impact-use approval is specified. Do not infer power-impact suitability from the steel alloy alone.
Is LX-121 lifetime coverage automatic?
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.
Can I use the socket if the magnetic ring is breaking apart?
Stop using the damaged socket and contact Lexivon. Loose fragments near a plug well need attention before work continues; no approved magnet repair is established.
What if the socket covers only part of the plug hex?
Stop and check the plug, socket seating and engagement before applying force. Do not use partial contact as confirmation of a suitable fit.
Should I keep using it if the socket cracks or the joint is damaged?
Stop using the damaged tool and contact Lexivon for assessment. No approved home repair or disassembly procedure is supplied.
Should I inspect the magnetic socket for loose debris before use?
Yes. Check that the tool and magnet are intact and free of loose material before working over the plug well. If material is shedding or a component is damaged, stop and contact Lexivon.
Can I treat a socket that slips as a correct fit?
No. Stop and verify opening size, full seating and the condition of the plug hex and socket. A magnetic grip alone does not establish secure hex engagement.
Does the warranty promise a free replacement for any wear?
No. Warranty covers defects in material and workmanship and excludes normal wear, misuse, modifications and non-original parts. Lexivon decides the resolution after assessment.
