The Multiquip D2131500404 Set Bolt is a genuine OEM component designed for SGW-250SS and SDW-225SS series welders. As a direct OEM replacement, this set bolt is sourced and validated by Multiquip to meet the original build specification for these machines. Confirmed fitment covers the SGW-250SS and SDW-225SS, making it straightforward to verify compatibility before ordering. DHS Equipment supplies this part to keep your Multiquip welder operating as it was built to perform.
Key Features
- Genuine OEM Construction — Manufactured to the same specification as the original set bolt, ensuring correct thread engagement, shank diameter, and hardness grade for secure clamping performance.
- Drop-In Replacement — Matches the original mounting position and thread pattern, allowing straightforward installation without rework or modification to surrounding components.
- Confirmed Welder Fitment — Verified for the Multiquip SGW-250SS and SDW-225SS welder models using the OEM part number D2131500404.
- Secure Clamping and Positioning — A correctly installed set bolt maintains precise component alignment within the welder assembly; a worn or missing set bolt can allow critical components to shift, affecting output consistency and joint integrity.
- Electrical Safety Relevance — In welder assemblies, loose or failed set bolts in terminal and component mounting positions can introduce resistance at connection points, creating heat buildup and potential arc faults — proper seating of this part directly supports safe operation.
A set bolt is a fully threaded fastener used to lock or clamp a component firmly in place within an assembly, typically applying pressure against a shaft, housing, or mating surface rather than passing through a clearance hole. In welder assemblies such as the SGW-250SS and SDW-225SS, set bolts secure internal components against movement under load and vibration, maintaining the positional accuracy needed for consistent electrical output. When a set bolt loosens or fails, the component it retains can shift, leading to increased wear, loss of electrical contact, or structural instability within the unit.
