Multiquip DM1640 Special Dome Head Bolt M8

The Multiquip DM1640 Special Dome Head Bolt M8 is a genuine OEM fastener designed for MQ Mixer equipment, including the MC3 MIX-N-GO Briggs Electric and MC3PBAT models. Sourced directly from Multiquip, this bolt delivers the exact thread specification, head profile, and material grade required by the original design. If you are servicing or rebuilding a compatible MQ Mixer, using the correct OEM fastener ensures the assembly torques properly and holds securely under operating loads.

Key Features

• OEM-Grade Fastener Material — Manufactured to the original M8 thread pitch and dome head geometry, ensuring correct clamp load and seating without distortion.
• Direct Drop-In Replacement — Matches the original bolt position and head clearance in the mixer assembly, allowing straightforward installation without reworking surrounding hardware.
• Confirmed Fitment — Genuine OEM replacement verified for MC3 MIX-N-GO Briggs Electric and MC3PBAT MQ Mixer models.
• Structural Integrity Under Continuous Load — The dome head profile distributes clamping force evenly across the mating surface, resisting loosening caused by the vibration and torque cycles typical of mixer operation.
• Correct Hardware Prevents Assembly Failures — Substituting an incorrect bolt size or head style can lead to stripped threads, cracked housings, or fastener backing out during use — OEM hardware eliminates that risk.

A dome head bolt is a structural fastener used to clamp and secure components within the mixer assembly. The rounded dome profile seats flush against curved or countered mating surfaces, spreading load and resisting pull-through better than a flat washer-face bolt in the same application. When a fastener of this type is missing, worn, or replaced with an incorrect substitute, the joint can work loose under the rotational and vibrational stresses of mixing, potentially causing component misalignment or mechanical failure.
