Four-Inch Format For XZN Access
10 extra-long XZN triple square bit sockets covering M4-M18. Match the fastener, tool connection and available clearance before applying force.

LX-145L is the extra-long 4-inch XZN set, with ten sizes from M4 to M18 and a carry case. M14, M16 and M18 are tamper-proof. Choose the long format for access that requires its published reach, then check surrounding clearance; longer bits do not establish a higher torque rating.
10 extra-long XZN triple square bit sockets covering M4-M18. Match the fastener, tool connection and available clearance before applying force.

The extra-long format is 4 inches. Confirm the separate exposed-bit length for each required size before choosing it for a depth-critical job.

Heat-treated S2 alloy steel bits. Chrome vanadium sockets connect them to manual drive tools.

Use only accessories rated for the tool in use. A material or finish claim does not establish an impact rating or a universal torque limit.

The package supplies 10 bit sockets and a storage case. Check every included size when unpacking. No ratchet or torque wrench is listed as included.

Match the profile, exact size, tool connection and available clearance. A vehicle name alone does not establish fit.
| Fastener or tool | Fit | What to check |
|---|---|---|
| Matching extra-long XZN triple square fasteners | Yes, in the listed sizes | Check the full size inventory below and seat the correct profile completely. |
| Other fastener profiles | No verified fit | Torx, external E-Torx and hex profiles require the matching tool. |
| Manual ratchets and torque tools | With matching connection | Match the square drive to each socket; fastener size and drive size are different. |
| Powered impact tools | No rating established here | Use only accessories explicitly rated for the powered tool and its torque. |
| A vehicle make or model | Conditional | Check the actual fastener profile, size and clearance; a vehicle name is not a fit guarantee. |
| High-torque or confined work | Requires verification | No per-size torque limit or guaranteed access dimension is verified; check the service procedure. |
Yes, when the fastener calls for one of the ten included XZN sizes and the 4-inch format fits the available access. A European vehicle make alone does not confirm the size, profile or clearance.
No. Match the required M-size to the ten included XZN sizes and check space for the long assembled bit and drive tool. The 4-inch format does not guarantee reach or clearance for every Volkswagen fastener.
1/4 inch: M4, M5, M6; 3/8 inch: M8, M9, M10, M12, M14 (tamper-proof); 1/2 inch: M16 (tamper-proof), M18 (tamper-proof).
No verified interchangeable fit is established. Use the XZN triple-square profile and exact specified M-size rather than a similar-looking Torx or hex tool.
No. M14, M16 and M18 are tamper-proof; M4, M5, M6, M8, M9, M10 and M12 are solid.
No. M6 is in the 1/4-inch drive group, while M8 starts the 3/8-inch group. The shared extra-long format does not make their ratchet connections the same.
LX-145L assigns M16 and M18 to 1/2-inch square drives. Both are tamper-proof pieces; use the matching drive and verify the equipment torque without inferring strength from the 4-inch format.
No impact rating is verified in the available specifications. Use only accessories expressly rated for the powered tool and its torque; steel type alone is not proof of suitability.
Its ten sizes include only three listed tamper-proof pieces: M14, M16 and M18. The seven smaller XZN sizes are solid, so long reach does not turn them into center-pin security tools.
LX-145L has a 4-inch extra-long format. Confirm each required M-size's exposed and assembled working length before a depth-critical job; the format alone does not give those separate measurements.
The extra-long format can meet a reach requirement but also needs space for the bit and drive tool. No specific vehicle-clearance guarantee is documented; compare the recess depth and surrounding space before choosing LX-145L over a shorter format.
LX-145L contains ten XZN bit sockets: M4, M5, M6, M8, M9, M10, M12, M14, M16 and M18. M14, M16 and M18 are tamper-proof; the other seven are solid.
LX-145L is described as extra long at 4 inches. LX-145 lists the same ten XZN sizes, M4 through M18, with tamper-proof M14, M16 and M18. Choose by reach and surrounding clearance; a longer bit does not establish a higher torque rating.
The package contains ten XZN bit sockets: M4, M5, M6, M8, M9, M10, M12, M14, M16 and M18, plus a carry case.
Lifetime coverage when you register online within 90 days of purchase; 12 months standard without registration. Commercial use has 12 months of coverage and cannot be extended; industrial use is not covered. Coverage is for defects in materials and workmanship, excluding normal wear, misuse, modification and non-original parts.
Do not assume so. LX-145L is the 4-inch format with ten XZN sizes; LX-145S is low-profile with eight solid pieces and an aluminum rail. Match the required reach and clearance, and note that the short set omits M9 and M18.
The models share nominal XZN sizes, but do not assume identical bit lengths or interchangeable replacements. Ask Lexivon for the exact LX-145L size and long-format component when confirming current ordering options.
No. 8.39 x 5.9 x 1.9 inches are package dimensions and 2.84 lb is package weight. They describe the packed long set, separately from its 4-inch extra-long tool format.
Match the specified M-size first. All three are listed as tamper-proof; M14 uses a 3/8-inch drive while M16 and M18 need 1/2 inch. Verify that the long format can seat fully before applying force.
Stop using the damaged piece and contact Lexivon with the model, issue description and clear photos. A break alone does not establish a covered defect; Lexivon assesses warranty eligibility.
Contact Lexivon with LX-145L, the affected XZN size and a clear description of the issue. Replacement handling depends on the assessment and available parts; do not assume an individual long bit is sold separately or substitute a shorter standard bit.
Reach and torque capacity are separate requirements. No higher torque rating is established for LX-145L relative to LX-145; avoid excessive force and use a drive tool and accessory confirmed for the fastener specification.
No. Use it for fastening with a suitable drive tool. Do not use a socket as a hammer, chisel or for other non-fastening tasks.
No. Coverage excludes normal wear, misuse, modification and damage from non-original parts. Commercial use is limited to 12 months without extension; industrial use is excluded. Torque-wrench recalibration is also excluded.
