The Multiquip 0021004020 is a genuine OEM Machine Screw designed for a wide range of Multiquip gasoline-powered generators, diesel-powered generators, and arc welders. As a direct factory replacement, this screw is produced to the exact dimensions and material specification of the original hardware, ensuring a flush, secure fit without modification. It is confirmed compatible with generator models including GA6HB, GA6HEB, GA3.6HR, GAC6HR, GAC6HRS, GAC3.6HR, GA6HR, GA6HRS, DA7000SSA2, and DA7000SSA2GH, as well as GAW180HE, GAW180HEA, and GAW180HE1 arc welder units. Sourcing this part directly through DHS Equipment means you receive the correct Multiquip OEM component — not a generic substitute.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's original material and thread specification, so torque values and clamp load match what the assembly was engineered for.
- Drop-In Installation — Thread pitch, head type, and length are identical to the original, allowing the screw to seat and tighten exactly as it did from the factory.
- Broad Generator and Welder Coverage — Fits GA6HB, GA6HEB, GA3.6HR, GAC6HR, GAC6HRS, GAC3.6HR, GA6HR, GA6HRS, GA6HRSNC2, DA7000SSA2, DA7000SSA2GH, GAW180HE, GAW180HEA, and GAW180HE1 equipment.
- Structural Integrity Restored — A correctly specified screw maintains panel, housing, and component alignment; an undersized or mismatched fastener can work loose under vibration, leading to component shift or damage.
- Electrical Safety Relevance — On generator and welder housings, properly torqued fasteners keep protective covers and grounding points secure, which is critical for safe electrical operation.
A machine screw is a precision fastener used to secure panels, brackets, covers, and internal components throughout a generator or welder assembly. Unlike a standard sheet-metal screw, a machine screw threads into a tapped hole or pairs with a nut, providing a controlled, repeatable clamp force that holds up under continuous vibration and heat cycling. When a machine screw strips, shears, or goes missing, the components it holds can shift or separate, creating misalignment, rattling, or exposed electrical contacts. Replacing it with the correct OEM-specified fastener — proper thread form, head style, and material — restores the assembly to its designed condition and prevents further wear on surrounding hardware.
