The Multiquip EM961045 Set Screw 5/16" NC x 3/4" is a genuine OEM fastener designed for MC44S, EM120SM, EM12M Series, and EM900SD concrete and mortar mixers. As a direct OEM replacement, this set screw is manufactured to the same material grade and thread specification as the original hardware, ensuring a secure, rattle-free fit right out of the box. Confirm your model code before ordering — this part is verified for the MQ Mixers and Essick Mixers families listed above. Keeping the correct fasteners in place is critical to maintaining proper component alignment and preventing costly drivetrain wear.
Key Features
- OEM Thread Accuracy: — Cut to 5/16" NC x 3/4" specification, matching the original thread pitch and engagement depth to prevent stripping or cross-threading on reinstallation.
- Drop-In Hardware Replacement: — Installs directly into the existing threaded bore with no rework needed — same hex drive size and seating geometry as the factory part.
- Broad Mixer Compatibility: — Fits MC44S, EM120SM, EM12M Series, and EM900SD models, covering both Multiquip MQ Mixer and Essick Mixer families.
- Secure Component Retention: — A properly torqued set screw locks rotating or sliding components in position; a worn or missing screw allows unwanted movement that accelerates wear on shafts, hubs, and adjacent parts.
- Genuine Multiquip OEM Part: — Sourced directly from Multiquip, so the alloy grade, surface treatment, and dimensional tolerances match what came off the assembly line — not a generic hardware-bin substitute.
A set screw is a headless fastener threaded fully through a collar, hub, or housing to bear directly against a shaft or mating surface, locking a component in a fixed rotational or axial position. In a concrete or mortar mixer, set screws are commonly used to secure agitator paddles, pulleys, and drum drive components to their respective shafts. When a set screw loosens or backs out, the secured component can shift under load, causing uneven mixing, accelerated shaft wear, and potential mechanical failure that sidelines the machine mid-pour.
