The Shacman X5000 Tool Box Lock Bracket Assembly is a genuine OEM component designed to mount the lock cylinder on the left toolbox of Shacman X5000 heavy trucks. This small but critical assembly ensures that the toolbox lid stays securely closed and opens only when intended. The kit includes one Tool Box Lock Bracket (DZ14251290040) and two Welded Hex Nuts (Q370C06). Every Shacman X5000 Tool Box Lock Bracket Assembly part is manufactured to original Shacman specifications for a direct, no-modification replacement. Below each component is described in detail.
The Shacman X5000 Tool Box Lock Bracket Assembly Tool Box Lock Bracket is a precision‑stamped steel bracket that holds the toolbox lock cylinder in place. It is manufactured from 2.0mm thick cold‑rolled steel with a zinc‑plated finish (720h salt spray resistance). The Shacman X5000 Tool Box Lock Bracket Assembly bracket features two square holes that accept the welded hex nuts, creating captive threaded mounting points. Its precise bend geometry ensures that the lock aligns perfectly with the toolbox latch mechanism, preventing binding or misalignment. This bracket is a direct replacement for the original part and eliminates the need to replace the entire toolbox body when only the lock mounting is damaged.
Two Shacman X5000 Tool Box Lock Bracket Assembly M6 welded hex nuts are included. These nuts are designed to be resistance‑welded into the square recesses of the lock bracket, creating permanent, non‑rotating threaded inserts. The nut is made from low‑carbon steel (C10C) and has a flange base that increases weld surface area. After welding, the nut provides a class 8 thread (M6 x 1.0) that accepts the lock assembly’s mounting screws. The Shacman X5000 Tool Box Lock Bracket Assembly zinc plating protects against corrosion even in high‑humidity environments. If the original nuts are stripped or missing, these welded nuts restore the bracket’s functionality without requiring bracket replacement.

Weldable square baseThe Tool Box Lock Bracket (DZ14251290040) is designed to be bolted to the inner wall of the left toolbox body. It has two 6.2mm square holes that exactly match the shape of the Welded Hex Nut. The nuts can be either spot‑welded or simply pressed into these holes; the square shape prevents rotation when the lock mounting screws are tightened.
The bracket also includes a raised embossment around the lock cylinder hole. This creates a recess that accepts the lock housing, centering it automatically during assembly. The overall dimensions are 80mm x 40mm x 20mm, with a weight of 85g.
The Q370C06 nut is a specialised weld nut with three small projections (pilot tips) on the flange face. When resistance welding is applied, these projections melt and fuse the nut to the steel bracket, creating a permanent bond. The nut’s flange diameter is 14mm, and the overall height is 7mm. Thread pitch is standard M6 coarse (1.0mm). The nut conforms to DIN 928 specification for weld nuts.
Step 1: Remove the toolbox lid and access the interior of the toolbox body where the lock is mounted.
Step 2: Unscrew the two M6 bolts holding the old lock bracket. Remove the old bracket and any loose or damaged nuts.
Step 3: If using a spot welder, place the two Welded Hex Nuts into the square holes of the new bracket and weld them in place. If no welder is available, press the nuts into the holes – they will remain captive under the lock’s bolts.
Step 4: Position the new bracket onto the toolbox body aligning the two mounting holes. Use the original M6 screws (or new ones, not included) to secure the bracket. Torque to 10 Nm.
Step 5: Install the lock cylinder onto the bracket using the two lock mounting screws (not included). Tighten evenly.
Step 6: Reattach the toolbox lid and test the lock operation. The key should turn smoothly and the latch should engage positively.
This lock bracket assembly is designed for the left side toolbox on Shacman X5000 series trucks (all years 2018‑2026). It is also compatible with the left toolbox of certain X3000 models that use the identical bracket. The bracket replaces original part numbers DZ14251290038 and DZ14251290039. The welded hex nuts supersede Q370C06A and are identical to those used in many other Shacman trim components. For the right side toolbox, a mirror‑image bracket (DZ14251290041) is available separately.
Reduce theft risk: A properly mounted lock bracket ensures the toolbox lock engages fully, preventing unauthorized opening. This small repair protects valuable tools and equipment.
Eliminate rattles: A loose lock bracket is a common source of toolbox rattles. Replacing it with a new, tight‑fitting bracket removes the annoyance.
Quick, standardised repair: One part number covers both bracket and nuts. No need to source separate hardware. Average repair time: 10 minutes.
Global availability: Stocked in regional warehouses. Same‑day dispatch for urgent fleet orders; bulk pricing for orders of 20+ kits.
Independent testing confirmed the bracket withstands 200N of pull force from the lock latch without deformation. The zinc plating showed no red rust after 720 hours of salt spray (ASTM B117). The welded hex nuts maintained thread integrity after 20 installation cycles with a torque of 10 Nm. The square profile prevented spinning even when the weld was not applied.
Do I need to weld the nuts? – No, welding is optional. The nuts are designed to be press‑fitted into the square holes; the square shape prevents rotation even without welding. Welding is only for original factory assembly.
What bolts are used to attach the lock to the bracket? – The lock cylinder uses two M6x16 bolts, which are not included. Reuse the original bolts or order Q1840616T1F31 separately.
Can this bracket be used on the right side toolbox? – No, the left and right brackets are mirror images. Order DZ14251290041 for the right side.
Does the bracket come pre‑welded with nuts? – No, the kit includes loose nuts. However, they can be pressed in without welding, or a local workshop can spot‑weld them in seconds.
What is the warranty coverage? – 24 months against bending, cracking, corrosion of the bracket, and thread stripping of the nuts.
The Shacman X5000 Tool Box Lock Bracket Assembly complies with EU ELV Directive 2000/53/EC and RoHS 2011/65/EU. The zinc plating uses trivalent chromium (no hexavalent chromium). The steel is 100% recyclable, and the cardboard packaging uses 90% recycled content. The nuts are free from cadmium and lead.
Quality assurance: Aftermarket brackets often use thinner gauge steel (1.5mm vs 2.0mm) and skip the zinc plating, leading to rust in 6 months. The genuine bracket uses HSLA steel and a multi‑layer coating.
Precision alignment: Aftermarket brackets frequently have misaligned lock cylinder holes, causing the key to bind. Genuine brackets are 100% dimensionally verified.
Full traceability: Each bracket is stamped with a production batch code, enabling quality tracking. Aftermarket parts have no such traceability.
