The Multiquip 0012312030 Hex Head Bolt is a genuine OEM fastener designed for DLW-series diesel light welder models including DLW300ES, DLW330X2, DLW400ESA4, DLW400ES, and DLW500ESA4. As a factory-sourced component, this bolt meets the exact dimensional and material specifications called out in the original Multiquip engineering documentation for these machines. Sourcing the correct OEM hardware ensures proper torque retention and long-term structural integrity in the assembly it secures. DHS Equipment stocks this part to keep your DLW-series welder running as Multiquip intended.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact tensile strength and thread specification required for the DLW-series welder application, ensuring the bolt holds under the vibration and load conditions these machines generate.
- Direct-Fit Hardware — Thread pitch, shank diameter, and head geometry match the original fastener, so installation is straightforward with standard tooling and no rework of mating components.
- Broad DLW-Series Compatibility — Confirmed fitment across DLW300ES, DLW330X2, DLW400ESA4, DLW400ES, and DLW500ESA4 diesel light welder models.
- Structural Integrity Under Load — A correctly torqued, properly spec'd bolt maintains clamping force on critical assemblies; an incorrect or worn fastener can allow loosening, misalignment, or component failure during operation.
- Sourced Through an Authorized Multiquip Dealer — Fulfilled by DHS Equipment, an authorized Multiquip parts distributor, so the part number, grade, and origin are verified before it ships.
A hex head bolt may be a small component, but it plays a critical role in securing structural and mechanical assemblies throughout a diesel light welder. These fasteners are engineered to a specific grade and thread specification so they maintain clamping force even when the machine is subject to engine vibration and repeated thermal cycling. Using a bolt of the wrong grade, thread pitch, or head size can result in insufficient clamping load, loosening over time, or damage to threaded bores — all of which can cause assembly failures that are far more costly to repair than replacing a single fastener.
