Multiquip 0015310045 Hex Socket Head Cap Screw

The Multiquip 0015310045 is a genuine OEM Hex Socket Head Cap Screw designed for DCA ultra-silent and super-silent series diesel generators and MQP standby generators. As a direct OEM replacement sourced from Multiquip, this fastener meets the original engineering specifications for thread pitch, head geometry, and material grade. Confirmed fitment includes DCA125SSIU4F, DCA125USI3CAN, DCA45SSIU4, DCA70SSIU2, DCA150SSI, DCA150SSIU, DCA180SSI, DCA180SSIU, DCA600SSK-GEER, DCA800SSK-GEER, and MQP56. When you need a fastener that installs correctly the first time, the part is the part to order.

Key Features

• OEM-Grade Fastener Integrity — Manufactured to the exact material grade, thread pitch, and torque specification called out in Multiquip's engineering drawings for these generator families.
• Direct Drop-In Installation — Internal hex drive head seats flush and engages precisely with the mating boss or bracket, eliminating fitment guesswork during reassembly.
• Broad DCA and MQP Compatibility — Fits DCA45SSIU4, DCA70SSIU2, DCA125SSIU4F, DCA150SSI/SSIU, DCA180SSI/SSIU, DCA600SSK-GEER, DCA800SSK-GEER, DCA125USI3CAN, and MQP56 generators.
• Structural Security Under Load — Correct clamping force on generator enclosure panels, engine mounts, and auxiliary components depends on using the right fastener — the wrong spec can lead to loosening under vibration.
• Genuine Multiquip OEM Part — Supplied as original equipment, not a generic substitute, so thread engagement and head drive dimensions match the assembly exactly as built.

A hex socket head cap screw — commonly called an Allen head bolt — uses an internal hexagonal recess to transmit drive torque during installation and removal. This design allows higher torque application in tight or recessed spaces where a standard hex head wrench cannot reach. On diesel generator sets like the DCA and MQP series, these screws secure critical structural and mechanical connections including enclosure panels, mounting brackets, and engine ancillaries. A fastener that is the wrong thread pitch, grade, or length can back out under the constant vibration of a running generator, compromising the integrity of the joint and potentially causing component damage or misalignment.
