Ten XZN Sizes With Three Security Pieces
10 XZN triple square bit sockets covering M4-M18. Match the fastener, tool connection and available clearance before applying force.

LX-145 supplies ten XZN triple-square bit sockets from M4 to M18 in a carry case. M14, M16 and M18 are the listed tamper-proof sizes; the other seven are solid. Choose it for the exact XZN fastener and square drive required by the service procedure.
10 XZN triple square bit sockets covering M4-M18. Match the fastener, tool connection and available clearance before applying force.

Only M14, M16 and M18 are listed as tamper-proof; the smaller sizes are solid.

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 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 service procedure calls for an included XZN triple-square M-size and the tool rating and access suit the job. A European vehicle make alone does not confirm every fastener's fit.
The set includes an M18 tamper-proof triple-square bit on a 1/2-inch square drive. Confirm the service-manual profile, engagement depth and tool rating; no generic wheel-bearing torque value is supplied.
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.
M4, M5 and M6 use 1/4-inch square drives in LX-145. The next size, M8, moves to a 3/8-inch connection, so the same ratchet does not directly fit every piece.
M14 is the largest listed XZN piece on a 3/8-inch square drive. M16 and M18 use 1/2 inch, even though all three are the tamper-proof versions.
Use LX-145 with suitable manual torque tools. Confirm a powered-impact rating for the exact XZN piece and tool before impact use; the ten-piece count and steel type do not establish that rating.
No. The listed solid sizes are M4, M5, M6, M8, M9, M10 and M12. Only M14, M16 and M18 are identified as tamper-proof in this standard-format XZN inventory.
M7 is not listed. LX-145 moves from M6 on a 1/4-inch drive to M8 on a 3/8-inch drive; select another confirmed tool if the job actually specifies M7.
No 4-inch extra-long length is specified for this standard model. LX-145L carries that published format and the same ten nominal XZN sizes; compare working access rather than assuming the standard set has the long reach.
Follow the vehicle service procedure and use a tool rated for that job. M14 is a tamper-proof XZN piece on a 3/8-inch drive; neither its size nor a stuck bolt establishes a safe torque ceiling or extension length.
LX-145 and LX-145L list the same ten XZN sizes, M4 through M18, with tamper-proof M14, M16 and M18. LX-145L is described as extra long at 4 inches. Choose by access and clearance; no extra torque capacity is verified for the longer model.
The ten-piece inventory includes one M9 solid bit and one M14 tamper-proof bit, both on 3/8-inch drives. A carry case is included; duplicated M9 pieces do not replace the required M14.
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.
LX-145 includes M9 and M18, which are absent from LX-145S, and its M14, M16 and M18 are tamper-proof. LX-145S lists eight solid low-profile pieces on an aluminum rail; choose by the missing size and required profile.
LX-145 XZN bits are sold as a set, rather than as individual retail pieces. Contact Lexivon about an exact M-size replacement and identify the standard model; do not substitute M8 for M9 or assume the long and short versions match.
Use LX-145 as the model number in place of the missing serial number when completing registration. Keep your proof of purchase; contact Lexivon if the form still will not accept the details. Register within 90 days of purchase for lifetime coverage.
For a matching center-pin XZN fastener, the documented choices here are M14, M16 and M18. Check the exact M-size and the 3/8- or 1/2-inch drive, then seat the bit fully with a suitably rated manual tool.
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.
The LX-145 inventory calls for M14 tamper-proof, not a second solid M9. Photograph the two M9 markings and the missing position and ask support to correct the contents; use a confirmed M14 for an M14 fastener.
Use this standard set for matching XZN triple-square fasteners. Stop using damaged tips; choose a tool designed for the actual extraction task rather than forcing an XZN bit into a stripped hex bolt.
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.
