Multiquip 0021004040 Machine Screw

The Multiquip 0021004040 Machine Screw is a genuine OEM fastener designed for Multiquip DCA Super-Silent and Ultra-Silent diesel generator series, including DCA25, DCA36, DCA45, DCA56, DCA70, DCA85, DCA125, DCA150, DCA180, DCA220, DCA250, and MQP56 models. As an OEM part, the part is manufactured to the exact thread spec, head profile, and material grade used on the original assembly, ensuring a correct match every time. Sourced directly through authorized Multiquip distribution, this screw is the same component installed at the factory across the full range of compatible DCA generator platforms.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the exact thread pitch, head type, and material specification used in original DCA generator assemblies, eliminating the guesswork of cross-referencing aftermarket hardware.
• Direct-Installation Fit — Matches the original mounting point dimensions exactly, threading into existing tapped holes without rework or thread chasing.
• Broad DCA Series Coverage — Compatible with DCA25, DCA36, DCA45, DCA56, DCA70, DCA85, DCA125, DCA150, DCA180, DCA220, DCA250 Super-Silent and Ultra-Silent generator models, as well as MQP56.
• Structural Integrity at Every Service Point — Proper fastener torque and engagement depth are critical to panel security, component retention, and enclosure integrity on portable generator sets; using the correct OEM screw maintains these tolerances.
• Electrical Enclosure Safety — On generator equipment, correct fastener seating ensures enclosure panels close flush and remain secure, supporting rated ingress protection and safe operation around electrical components.

A machine screw is a threaded fastener used to join or secure components at fixed, tapped mounting points throughout the generator assembly — from enclosure panels and control board brackets to internal housings and access covers. On DCA series generators, maintaining correct fastener specs is essential because undersized or incorrect-grade screws can back out under vibration, compromise panel alignment, or allow enclosure gaps that affect both weather resistance and electrical safety. Replacing a worn, stripped, or missing screw with the correct OEM part restores the assembly to its original clamping specification and keeps every secured component firmly in place during operation and transport.
